Comprehensive Benefit Evaluation of Water-saving Irrigation in Arid Farmland
Water resources in agricultural production are insufficient,leading to serious waste and low utilization efficiency.In response to this issue,this study proposes a comprehensive benefit evaluation model for water-saving irrigation in arid farmland,which is used to evaluate the comprehensive benefits of local water-saving irrigation.The experimental results indicate that in 2017,the comprehensive benefit scores for precipitation,evaporation,water use intensity and watershed area were 0.60,0.54,0.64 and 0.65,respectively.In 2021,the comprehensive benefit scores for precipitation,evaporation,water use intensity and watershed area were 0.78,0.75,0.82 and 0.86,respectively.The research results indicate that the evaluation of comprehensive benefits through the proposed game theory method can improve the comprehensive benefit evaluation of water-saving irrigation in arid farmland.
