Study on agricultural soil and water conservation based on analytic hierarchy process model

Abstract:
The water and soil environment of irrigation area plays a very important role in the regional ecological environment, especially the groundwater level, river ecological flow, water quality and total water consumption, which will cause a series of ecological environmental problems. Therefore, based on the research of ecological irrigation area, constructing an evaluation model of water and soil environment in irrigation area is of certain significance to explore the problems of water and soil environment in irrigation area. Combined with the actual situation of the irrigation area, this paper applies the fuzzy comprehensive evaluation method to comprehensively evaluate the water and soil environment of the irrigation area, uses the analytic hierarchy process to determine the weight of the evaluation index. The research content of this paper is helpful to the construction of water ecological health system in irrigation area. It can improve the utilization coefficient of irrigation water and the assurance rate of ecological water demand, reduce the exploitation of groundwater and the use of chemical fertilizer, supplement the short board of ecological environment in irrigation area, and make the water and soil environment in irrigation area more healthy.
