Zhecheng County 1 Overview of Irrigation and Water Conservancy Construction Projects
Zhecheng County is located in the east of Henan Province, which belongs to the Huaihe River basin and is the alluvial plain of the Yellow River. It is located in the southwest of Shangqiu City, with a total area of 1042km2 and cultivated land area of 71.500hm2.. The project area is located in the east of Zhecheng County, involving 3 townships ***5 1 administrative village. Seven drainage ditches are dredged in this project, with a total length of 5 1.85km and a total drainage area of 9500 hm2. Because of the staggered ditch network, the drainage area of each drainage ditch is repeated. Among them, the open trench is 22.20km, with a total drainage area of 0.7 1 10,000 hm2. Bazhang River is 7.30km, with a drainage area of 2000 hm2.
2 Zhecheng County Farmland Water Conservancy Construction Project Economic Benefit Analysis
2. 1 benefit calculation After the implementation of the farmland water conservancy capital construction project, the irrigation area can be increased by 2000 hm2, and the drainage area can be increased by 9500 hm2. After the completion of the project, the grain output will be greatly increased, and the agriculture and rural economy will continue to develop steadily, with an annual increase of 450,600 kilograms of grain and an annual per capita income of 27.23 yuan. The main crops in the project area are wheat in summer, corn in autumn, cotton, oilseeds and peanuts, among which grain crops account for 80% of the planting area, cash crops account for 20% of the planting area, and the multiple cropping index is 1.80. The benefit sharing coefficient of water conservancy production increase is 0.40.
2. 1. 1 After the completion of the irrigation efficiency calculation project, the irrigation area can be increased by 2000 hm2. Through the field investigation and statistical data analysis in 20 12 years, the yield of grain crops increased by about 150kg per hectare, the income of cash crops increased by 300 yuan /hm2, and the comprehensive price of grain was 1.80 yuan /kg. The annual yield increase benefit is: b1= (3.03×1.80× 80 %×1.80+3.03×1.80× 20 %× 0.40). The loss can be reduced after the completion of this project: B2 = (14.30×1.80× 80 %× 7×1.80+14.30×1.80× 20 %×/.
3 Zhecheng County farmland water conservancy construction project social benefit analysis
3. 1 The implementation of the farmland water conservancy capital construction project in Zhecheng County fully embodies the important spirit of the central government to solve the "three rural issues" and is a popular project for the government to do practical things for the people. Due to the long-term lack of construction funds, farmland water conservancy facilities are in disrepair, which seriously restricts agricultural production. Irrigation and water conservancy capital construction projects with the main goal of improving agricultural production and farmers' living conditions have become an important measure to increase farmers' income. Judging from the source and flow of project funds and the management and organization requirements after the implementation of the project, the capital construction of farmland water conservancy itself is an important means to narrow the gap between urban and rural areas and promote the economic and cultural development of the whole society. After the implementation of the project, the biggest beneficiaries are the farmers in the project area. Therefore, the project has been strongly supported and embraced by farmers.
3.2 It laid a foundation for agricultural mechanization, biological, intensive and intelligent production. The implementation of the project has important practical significance for introducing and adopting new agricultural technologies, changing traditional concepts, using modern agricultural management methods, building new rural communities, and promoting rural economic modernization and all-round development of rural society.
3.3 Improve the ability of agriculture to resist natural disasters. After the drainage ditch is dredged, the drainage capacity of farmland will be greatly improved, and agriculture will gradually develop into high-quality and efficient agriculture. Ensure a bumper harvest of crops, increase farmers' income and gradually improve farmers' living standards, so as to reduce the government's investment in poverty alleviation funds and reduce the financial burden.
4 Zhecheng County farmland water conservancy construction project eco-environmental benefits analysis
The implementation of the project has improved the agricultural drainage conditions in Zhecheng County, and the crops have been drained in time, which has enhanced the ability of crops to resist pests and diseases, improved the multiple cropping index of crops, and increased the planting area of forests, fruits and grasses, thus greatly improving the plant coverage rate, and effectively controlling soil erosion with supporting measures and land leveling. At the same time, the project construction period and operation period will not cause pollution to the environment, and ultimately protect the natural ecological environment. After the implementation of the project, it will promote the development of rural economy and the comprehensive development and utilization of water resources in the project area. Trees and grass can be planted along Dounonggou, which plays a great role in regulating climate, beautifying environment and protecting ecology, and the ecological and environmental benefits of the project are very remarkable. 5 Benefit Analysis and Summary After the implementation of the farmland water conservancy construction project in Zhecheng County, the irrigation area can be increased by 2000 hm2, the drainage area by 9500 hm2, the grain production capacity by 450600 kg, the total annual benefit is 94 1300 yuan, and the per capita annual income of farmers is 2,723 yuan.
At the same time, through the informatization construction of irrigation area, the management level of irrigation area has been improved, and the situation of neglecting management in the past irrigation area reconstruction has ended. After calculation, the economic internal rate of return of farmland water conservancy construction projects in Zhecheng County is 34.36%, which is greater than the social discount rate of 8%. The economic net present value is 3,285,600 yuan, greater than 0; The benefit-cost ratio is 2. 10, greater than 1.20, and all indicators meet the requirements of the specification, indicating that the project is economical and reasonable.
