Comprehensive Evaluation and Application Research on Water-Saving Engineering in Irrigation Areas in Southwestern China
In southwest China,water-saving projects in irrigated areas are of great significance for rational utilization of water resources and protection of ecological environment.Based on the analysis of irrigated areas in southwest China,this paper puts forward a comprehensive evaluation method for water-saving projects in irrigated areas.During the process,the general situation of the irrigation area was studied,the utilization coefficient of irrigation water was calculated,and then the evaluation system of water-saving engineering in the irrigation area was established and the grading standard of evaluation results was determined.In the experimental results,the 12 indexes of 5 irrigation districts were calculated without dimensionality.The 12 indexes of irrigation area were evaluated accurately.It shows that the research method has practical significance in the evaluation of irrigation area in southwest China.
