Establishment and Application of Evaluation Index System of Soil Salinization in Plain Reservoir: An Example for Shifosi Reservoir

Conference paper
Part of the Environmental Earth Sciences book series (EESCI)

Abstract

Plain reservoir surrounding soil salinization assessment method for the small scope of application, low evaluation precision of the common problems proposed for underground water level elevation, soil water salinity, evaporation and precipitation ratio were used as evaluation factors of the soil salinization assessment index system. Shifosi Reservoir, as an example, in the field water test obtained evaluation parameters based on using AHP fuzzy comprehensive evaluation method of the reservoir after impoundment and the degree of soil salinization was evaluated. The results show that the most serious salinization area is in the left bank of Shifosi Reservoir, after the impoundment of Shifosi reservoir; and closer to the main salinization is more serious, and away from the main dam area the salinization degree is gradually reduced. The right bank of the terrain is relatively low in soil salinization degree due to a serious problem in most parts; less parts presented mild salinization. According to the result of the evaluation, the measures of prevention and control of the salinization of precipitation and water supply were determined, and the rational development and utilization of water resources were realized. This study provides a new idea for the evaluation of soil salinization and provides a scientific basis for the control and prevention of environmental geological hazards in the reservoir area.
