Preface of 0
Clustering of geological data information service is an important reform of mining administration management, a fundamental measure to solve the problems existing in geological data management, and a major change to the traditional service concept, service mode and service ability. It is also the focus of geological data management in Guangdong province in the next few years, and it is a huge system construction project. Over the past decades, various geological departments in Guangdong Province have carried out a lot of geological work and accumulated a large number of professional materials such as basic geology and mineral geology. Due to historical and technical reasons, some of these materials are scattered in various departments, and some are still paper materials. The management and application of geological data encounter information "islands", that is, various geological data can not be communicated, shared and comprehensively utilized, which leads to repeated investigations and waste of investment. The great potential value of geological data information has not been fully exerted.
With the rapid development of computer, network and other related technologies, the integration, management and visualization of massive information is no longer a difficult problem. Therefore, it is urgent to sort out the existing geological data, implement standardization, establish and store geological information database, deeply integrate massive geological information, realize its comprehensive integration and management, and promote the cluster construction of geological information service in Guangdong Province.
1 Present situation of geological data management and information service in Guangdong Province
1. 1 geological data information resources
Geological data include original geological data, achievement geological data and physical geological data. Geological data are classified by specialty, including basic geology, mineral geology, urban geology, hydrogeology, engineering geology, environmental geology, geological disasters, geophysics and geochemistry. The geological data of the above-mentioned majors in Guangdong Province are mainly received and kept by the Guangdong Provincial Land and Resources Archives in accordance with the Regulations on the Administration of Geological Data (the State Council Decree No.349), and provide utilization services to the whole society. At present, the submission of geological data in the whole province is not ideal, and there are still some cases of insufficient submission. Engineering geological data are basically not submitted in the whole province due to the lack of relevant supporting measures; Most of the hydrological and environmental geological data are in the provincial geological bureau, the provincial geological environment monitoring station and other related units; Most of the geological data of engineering geology and geophysical and geochemical exploration are in various geological teams under the Provincial Bureau of Geology. Geological data information resources are scattered.
1.2 network environment construction
At present, the Guangdong Provincial Land and Resources System has established a network system linking the Ministry of Land and Resources with the municipal and county land and resources bureaus, and the Provincial Land and Resources Archives has established a network resource environment of classified network, government network, internet separation and hierarchical management, which can be used as an integral part of the network environment of geological data information service clustering. However, there is no cross-industry and inter-departmental network environment for geological data management in the whole province, and geological data are scattered in the networks of various units, which is not interconnected and the construction level is different.
1.3 construction of geological data resources
The Provincial Archives of Land and Resources has completed the establishment of graphic database and catalogue database of all collected geological data, spatial database of reserves, spatial database of exploration and mining rights, and the establishment of geological data management and service system.
Based on the investigation of geological disasters in counties and cities of the province, the provincial geological environment monitoring station established the database of geological disasters in counties and cities of the province, and set about establishing a set of geological disaster early warning system in the province. Realize the dynamic management of geological disasters in the whole province, organically integrate geological environment background data, geological disaster data and real-time rainfall data through cooperation and data sharing with meteorological and hydrological departments, establish relevant early warning analysis models, realize the pre-disaster warning of geological disasters caused by meteorological factors, and provide effective time guarantee and regional focus for geological disaster prevention and emergency work in Guangdong Province.
The provincial geological bureau has a large number of original geological data. In recent years, the unit has basically completed the construction of1:200,000 digital geological map spatial database,1:200,000 hydrogeological map database, national mineral land database (Guangdong part) and1:200,000 heavy sand database. However, due to funds and other reasons, some aging or even seriously damaged geological data have not been effectively protected, and digital scanning and database building have not been carried out.
Guangzhou Urban Construction Archives has mastered almost all the engineering geological data in Guangzhou since the reform and opening up. The unit is rich in data resources and has a high level of information management, and several engineering geological databases have been built.
1.4 support services to the mining administration department
At present, the service support of geological data for mining administration mainly includes reserve management, mineral resources inquiry service covered by construction projects, verification of geological work degree in the early stage of geological exploration, geological disaster detection, groundwater monitoring and so on. Geological disaster database management system and groundwater database management system can only run on a single computer because of the limitation of their basic geographic information layer, and can not provide real-time and effective services for mining administration management. Mining right management information system and exploration right management information system of Mining Bureau use the system provided by the Ministry, but still do not use spatial database, and their functions are uneven, which can no longer meet the needs of daily administrative work. The query of mineral overburden still uses backward methods, which is inefficient.
1.5 service to the economic and social development of the whole province
Geological data are widely used in the planning and construction of construction projects, the development and utilization of mineral resources, disaster prevention and mitigation, scientific research and people's lives. The examination and approval of land for all construction projects, the development and utilization of mineral resources and the management of mining administration in the province are inseparable from the information service and support of geological data. Over the years, geological data have made outstanding achievements in serving the province's economic and social development and major engineering construction, especially in providing geological data information services for expanding domestic demand projects. In 20 10, the Provincial Archives of Land and Resources was rated as "the unit with remarkable achievements in maintaining growth and red line" by the Ministry of Land and Resources.
There is a problem
2. 1 The guarantee of geological data exchange system is weak and the exchange mechanism is not smooth.
Although "Regulations on Geological Data Management" clearly stipulates that geological data submitters must submit geological data to the competent department of land and resources, due to the lack of corresponding laws, regulations and administrative measures, submitters lack enthusiasm and initiative, and are still unable to "hand in all" at present, which brings great inconvenience to the construction of geological data information service cluster.
2.2 The degree of informatization of geological data is low, and the standards and specifications are not uniform.
Due to historical and technical reasons, geological data before 2002 were mostly managed in the form of paper maps, reports and statements. After 2002, according to the requirements of relevant laws and regulations, geological data have been submitted to the corresponding electronic data, but the data formats are mixed and the standards are not uniform, so it is difficult to manage directly under the same platform. Because the management of geological data formed in the past 60 years has not kept pace with the development of information technology, the management methods of geological data are backward, the service capacity is insufficient, and the utilization level is low, resulting in waste of resources and repeated investment in construction. Due to the lack of geological data information support, the informatization construction of mining administration can only be carried out according to a single business, and the management system construction on the information platform cannot be realized.
At present, in order to realize the cluster management and industrial application of historical data, it is necessary to break through the bottleneck of the disunity of standards and norms and build the geological data informatization standard for the industrialization of geological data clusters.
2.3 Difficulties in Multidimensional Geoscience Data Integration and * * * Service Platform Construction
Geological data involve many professional fields, including basic geology, mineral geology, hydrogeology, engineering geology, environmental geology, geological disasters, geophysics and geochemistry. , and has the characteristics of multi-time, multi-source, multi-format and massive heterogeneous data. In order to solve the professional problems of various industries, geological and mineral units have established many highly professional databases and application systems, such as geological disaster early warning and forecasting system, groundwater resources monitoring system, urban geological information system and so on. The contents of these database systems cross each other, but the management methods are quite different. How to integrate the existing geological data and establish a unified data sharing platform will be an urgent problem in the process of geological data clustering construction.
2.4 the lack of * * * to build a * * * enjoyment and benefit distribution mechanism
Geological data are divided into public welfare geological data and commercial geological data. Since the reform and opening up, all units have taken geological data as their own, and even need to rely on geological data to generate economic benefits to maintain the normal operation of the units. It is worried that the enjoyment of geological data will threaten the survival of the unit, so it is unwilling to submit or enjoy geological data. The cluster industrialization of geological data information service is a huge system engineering across departments and fields, which requires close cooperation and coordination among various departments. For example, coordination between provinces and localities, coordination between horizontal units and coordination between vertical units. It is necessary to establish an effective data sharing mechanism and benefit distribution mechanism, operate public welfare and commercial services on different platforms, develop different types of information products, and provide different levels of utilization services. It is necessary to open public welfare geological data, but also to protect commercial geological data and fully safeguard the interests of right holders. Let all the units involved in the construction of * * * * share the benefits of "industrialization and modernization" reasonably while undertaking their obligations. Therefore, it is the key to establish and improve the distribution mechanism of geological information data sharing and utilization.
2.5 Network interoperability and data security issues
The clustering construction of geological data will be interdisciplinary, cross-departmental and cross-administrative regions, but at present, inter-departmental and cross-administrative regional network interoperability has not been realized. The important content of cluster construction is to build geological data centers and realize the network interconnection between provincial geological data centers and horizontal and vertical data sub-centers. At the same time, it is necessary to establish data communication interfaces of various professional systems in a secure network environment to ensure the data flow between data centers and the safety of * * * *.
2.6 Lack of legal and administrative protection
The construction of geological data cluster project should first solve the problem of data integration and sharing between industries and departments. At present, the relevant units across departments are not bound by the Regulations on Geological Data Management, and data integration cannot be guaranteed. For example, urban engineering geological data are kept in urban construction archives, and urban construction archives have no obligation to enjoy urban engineering geological data. It is urgent to innovate geological data collection mechanism and establish geological data information service cluster system.
3 Guangdong geological data cluster construction ideas and methods
3. 1 construction concept
In view of the problems existing in the current geological data information clustering construction, combined with the actual situation of geological data management and application in Guangdong Province, and around the integration and service of geological information, two basic ideas of geological data clustering construction in Guangdong Province are put forward.
3. 1. 1 Realize the deep integration of geological information and geographic information resources.
The idea of geological data clustering construction is not only to realize the simple integration of traditional geological data management technology and GIS technology, but also to realize the seamless connection between geological data and other basic geographic information data. Make full use of the advantages of land and resources information data collected in Guangdong Province, and use the spatial platform constructed by basic geographic information data to realize the integration of multi-source information data resources under this platform, such as the superposition of image data and geological data, the geological data analysis of three-dimensional model, and the geographical relationship model between topography and geology and minerals.
3. 1.2 Theoretical Research on Realizing the Standard Specification of Geological Information System
Geological data clustering construction is not only the design of geological data clustering management system construction scheme, but also the theoretical research of geological information system standards and specifications. In the whole project research process, the standards and norms of classification, collection, collation and integration of geological data information are put forward.
3.2 Construction methods and working methods
3.2. 1 Establish and improve the sharing mechanism of geological data in the whole province.
Establish a geological data collection system under the background of clustering, innovate the data collection and sharing mechanism, initially form a long-term renewal mechanism of geological data center, and ensure the gradual advancement of clustering industrialization of geological data information services. The clustering and industrialization of geological data depend on the data exchange mechanism. On the basis of clustering, the system design of relevant geological data exchange is established, and the exchange relationship is straightened out to ensure the exchange of data and information. Taking the cluster project construction as an opportunity, we will build a multi-party win-win mechanism for geological data information resources, and form a benign mechanism in which the government builds a basic platform and geological units and enterprises participate extensively.
3.2.2 Cluster all kinds of geological data information to form a basic data management service support system.
Complete the clearing of achievements, original and physical geological data in Guangdong Province, digitize important geological data that should be digitized, and build relevant databases. Integrate existing geological data information and data resources, and cooperate with relevant departments and units to build Guangdong Geological Data Center system. Through the collection and integration of all kinds of geological data information, a provincial geological data center will be formed to realize a comprehensive grasp of Guangdong's geological resources and their development and utilization, laying a good foundation for building a "one map" database of land resources in the province. Guangdong Province Distributed Geological Data Center will be built to provide geological data information services for the utilization and development of governments at all levels and the geological industry by using geological data clustering results.
3.2.3 Establish geological data information service platform and network service system to realize diversification of geological data information service channels and modes.
There are two main aspects of geological data application service: one is to serve the government; The second is to serve the geological industry and the public, and build an application service platform for these two levels of service objects. Guided by application service, we will expand the application of clustered geological data in government departments and geological industries, and realize the diversification of geological data information service channels and service methods.
Based on the geological data center, typical application case studies are carried out, such as strengthening the supervision service of mining rights, building a service platform for evaluating the value of mineral resources reserves in the province, and a platform for analyzing and forecasting mineral resources based on WebGIS.
Focus on the development and utilization of information resources and * * * services, make full use of the existing foundation, take overall planning, integration, establishment of systems and exploration mechanisms as the guidance, meet the growing demand of economic and social development for geological information, cultivate and promote the formation of related information industries and the prosperous development of geological and mineral markets, build a multi-level and distributed geological information service cluster framework under a unified technical environment, and realize rich, diverse and extensive geological information services.
3.2.4 Deepen the development and utilization of geological data information resources, and gradually promote the industrialization of geological data information services.
Actively follow up, capture and explore the geological data requirements of government management support services and industrial and social application services. Based on the geological data information service platform, we will deepen the development and utilization of geological data information resources, enhance the pertinence and flexibility of participating in macro-control, provide geological data information service products that meet different needs, and gradually promote the industrial development of geological data information services.
4 conclusion
Clustering geological data information service is a huge system construction project. It is necessary to promote the integration and synthesis of geological data information with multi-unit, multi-department, multi-specialty and multi-level distribution, fully tap geological data information resources, and realize that geological data provides comprehensive, professional, convenient and efficient services for economic and social development, thereby improving the supporting ability of geological work for economic and social development.
