In order to fully understand the actual needs of geological survey information users and do a good job in the demand analysis of public welfare basic geological survey, the China Geological Survey and the Information Center of the Ministry of Land and Resources conducted a questionnaire survey on geological survey information demand in June 20001. A total of 527 questionnaires were sent out, and 252 were recovered, with a recovery rate of 48%. Among them, the geological prospecting units of land and resources system recovered 167, the scientific research institutes recovered 25, and the geological prospecting departments of industrial systems recovered 60. See table 8- 1 for the basic information of the respondents.
Table 8- 1 Basic Information Table of Respondents
After a comprehensive analysis of the questionnaire, the following basic conclusions are drawn:
(1) Generally speaking, geological survey results are important and credible, but their timeliness and popularity are poor. 98% of the respondents think that geological information is important, but 65% think that geological information is not timely. Although all the respondents in this questionnaire survey are geological professionals, there are still 18% people who think that geological maps are not readable. The expression of geological survey results is too specialized to be used by non-geological managers and decision makers. The slow updating speed of geological information does not meet the needs of national economic development, which is an important factor affecting the good application of geological survey results. Therefore, it has become an urgent problem to use modern high-tech exploration technology and information technology to update geological survey information as soon as possible, express geological survey results in an easy-to-understand form and provide services for the society.
(2) The socialized service level of geological survey results is low, so it is urgent to strengthen the informatization construction. The service scope of public welfare geological survey results is all industries and fields of the national economy, including the public. At this time, 39% of the respondents obtained geological information from geological survey institutions, followed by libraries (15%), scientific research institutes and institutions (14%), and only 5% of the respondents obtained geological information through the Internet, indicating that the popularization rate of information technology is still very low, and it is urgent to strengthen the informatization construction.
The investigation on the demand potential of digital geological products shows that 96% people need digital geological products, but only 3 1% of the respondents have used the website of China Geological Survey, indicating that 25% of them will not use it. Many interviewees suggested speeding up the pace of information system construction, enriching the content of the website, and releasing the results of digital geological survey in time.
(3) The demand for geological survey information is diversified, and the field of geological work services is constantly expanding. The survey shows that mineral resources and energy, regional geology, groundwater resources, geological disasters, geophysical and geochemical exploration and remote sensing technology, engineering geology, environment and ecological geology have the same demand for geological information, ranging from 12% to 15%, and coastal and marine geology is 6%, reflecting the diversified demand for geological information for national economic construction and social sustainable development. The service field of geological work is expanding from traditional prospecting to disaster reduction and prevention, land consolidation, environmental protection, sustainable development and planning of regional economy, major engineering construction, sustainable development of agriculture and human health.
In the basic geological survey, large and medium-scale geological maps are in great demand, with the scale of1∶ 50,000 being 31∶ 200,000 or1∶ 250,000 being 30%, while the small-scale geological maps are in weak demand, with the scale of1. The demand for geological maps with a scale greater than 654.38+100,000 is only 654.38+0%, which shows that large and medium-scale geological maps play an extremely important role in solving practical problems of regional social and economic development (Figure 8-2).
Figure 8-2 Comparison of Geological Information Demand Types
In the investigation, we can see that there are obvious changes by comparing the types of demand for geological information in the future with the geological information actually used. The demand for new technical methods, geophysical and geochemical profiles, geological prediction models, databases and geological maps has greatly increased. In fact, different geological information users will draw different conclusions and results from different angles and viewpoints, or use different processing methods. Therefore, the results provided by public welfare geological survey for social use should be based on objective, accurate and scientific raw data, and the reduction of demand for raw data in the future is related to the fact that the survey object is limited to geological technicians.
(4) In the questionnaire survey, the range of users of geological information is narrow. The geological information used by the respondents is mainly used for mineral resources planning, development and management (23%) and geological-related scientific research activities (20%), followed by regional economic development planning (12%), preliminary demonstration of basic engineering construction (12%) and environmental protection (1/kloc-0) The investigation shows that although there are many reasons, it is an indisputable fact that the geological survey results have not been fully utilized, which should be paid attention to by all parties and studied in depth.
It should be pointed out that the scope of this survey is limited to industries and departments engaged in geological survey, and the survey object is geological technicians. The survey results are inevitably limited and cannot fully reflect the demand intention and demand information of customers who use geological information.
