摘 要：
针对农田节水减污系统具有多属性、多指标的特点,选择总氮、氨氮、硝态氮、总磷、可溶磷等5项特征指标作为评价因子,引入熵值法来确定各评价指标的权重,建立了基于熵权的TOPSIS农田节水减污系统进行综合减污能力评价模型,并将该模型应用于桂林市青狮潭灌区及广西灌溉试验中心站农田节水减污系统进行减污能力的评价。应用结果表明:该模型计算简便、结果科学合理,为广西农业面源污染的削减与水肥高效利用提供理论和实践依据。

摘 要：
In this paper,based on Water saving and pollution reduction system of Irrigation and water conservancy has the characteristics of multi-attribute,multi-index,select 5 characteristic index evaluation and analysis,the TOPSIS comprehensive evaluation model was established,the weight of the evaluation index is determined to calculate the information entropy,comprehensive pollution reduction effect was evaluated using the optimal solution of Euclidean distance. The method is applied to Guilin city Qingshitan irrigation district and Guangxi irrigation experiment station,the result is reasonable,and calculation is simple; it was Provide theoretical and practical basis for the reduction of agricultural non-point source pollution and the efficient utilization of water and fertilizer in Guangxi.
