| Water is one of the indispensable conditions of human survival. Watching the world,there is currently no alternative to the status of water resources in the human development process. It can be said that if there is no water in this world, The origin of life, the development of human civilization can not be inherited and carried forward,human production and life can not do without water, the growth of crops and water is closely related. Agricultural water resources have a damaging effect on food security,and an important guarantee for food production. Hebei Province is located in the south of central China, is a subtropical humid climate, abundant rainfall, coupled with the Yangtze River and the Hanjiang River through the territory, the Han River water quality is excellent,water resources in the country ranked the whole row. Hebei,despite the abundant water supply on the surface, but because of the uneven distribution of water resources, coupled with climate change and residents, agriculture and industrial water consumption and water demand continues to increase in different parts of Hubei Province,Serious, that is, when the rainfall is concentrated and abundant rainfall, it will cause floods, when a long time without precipitation or precipitation is very little climate,Hubei part of the city may be faced with livestock and poultry without adequate drinking water, crop drought Water problem.Based on the theory of sustainable development, the theory of ecological economy and the theory of water resources carrying capacity,this paper,combined with the sustainable evaluation methods and relevant effective experiences of agricultural water resources at home and abroad,choose to adapt to the sustainable development of agricultural water resources in Hubei Province The AHP method was used to evaluate the evaluation index system, and the relevant countermeasures and suggestions were put forward according to the evaluation results.The main content of the article is divided into five chapters:Chapter 1, the author briefly introduces the research background and significance,and summarizes the domestic and foreign research from three aspects: the evaluation index, the evaluation method and the model of the sustainable use of water resources, and then the theory of sustainable development , Eco-economic theory and the sustainable use of agricultural water resources to do a brief description. And briefly introduced the research objectives, content, methods and technical routes.Chapter 2, built on the development of agricultural water resources in Hubei Province, the three-tier hierarchical structure system is established: target layer, criterion layer and index layer. The first layer is the subject layer is a single indicator, the second layer is the standard layer, a total of four. The third layer is a specific indicator, a total of 16 indicators.Chapter 3,this chapter is the focus of this paper,according to the calculation formula of the previous chapter, calculate the membership degree of Hubei Province and its states, and combine the standard reference values From resource subsystem, economic subsystem,population subsystem and ecological subsystem of the four aspects of Hubei Province and its state to conduct analysis. And then depending on the fuzzy evaluation model to calculate the sustainable utilization of agricultural water resources in Hubei Province and its municipalities, and evaluate the eigenvalues.Chapter 4, according to the above analysis, countermeasures and suggestions are put forward to promote the sustainable development of agricultural water resources in Hubei Province.Chapter 5, the conclusion and the prospect of the research, and summarizes the shortcomings and shortcomings of this study. At the same time, it wishes to point out the shortcomings and shortcomings in this study. |
