摘要
由于农业生产中水资源不足,存在浪费严重、利用效率低下等问题,为此研究提出一种针对干旱农田的节水灌溉综合效益评价模型,并通过该模型对当地的节水灌溉进行综合效益评价。结果显示,2017年降水量、蒸发量、用水强度和流域面积的综合效益评分依次为0.60、0.54、0.64和0.65;2021年降水量、蒸发量、用水强度和流域面积的综合效益评分依次为0.78、0.75、0.82和0.86。研究表明,通过所提出的博弈论法对综合效益的评估,可以改善干旱农田节水灌溉的综合效益评价。
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.
