摘　　要：由于化肥和农药施用量的不断增加,以及农村生活污水的任意排放,导致辽河流域农田面源污染治理面临巨大挑战。如何因地制宜地合理选择农田面源污染治理技术,尚缺乏科学有效的评价方法。构建了辽河流域农田面源污染治理技术评价指标体系,基于层次分析-模糊综合评价法对10种典型的农田面源污染治理技术进行了综合量化评价。采用层次分析法结合Spyder软件计算指标权重值,结果表明:氨氮去除率、TP去除率、水质净化效率、工程运行维护管理费用、冬季净化稳定性、景观多样性指数的综合权重值最高,是辽河流域农田面源污染治理技术的重要评价指标。采用模糊综合评价法与Matlab软件相结合计算指标隶属度与模糊综合评价值,结果表明:生态拦截沟渠技术的模糊综合指标值为3.8872,可作为过程拦截技术中的优选技术;人工湿地技术的模糊综合评价值为3.9304,可作为末端治理技术中的最优技术。该评价结果可为选择适宜的辽河流域农田面源污染治理技术提供理论依据,也可为其他同类污染治理技术评价和制订相关政策提供有效的理论支撑。Due to the increasing application of chemical fertilizers and pesticides in farmland and the random discharge of rural domestic sewage,the treatment of farmland non-point source pollution in Liaohe River is facing great challenges.At present,there is still a lack of scientific and effective evaluation methods on the farmland non-point source pollution control.In this study,an evaluation index system of farmland non-point source pollution control technology was constructed with 1 target layer,3 criteria layers,5 indicator layers,and 14 sub-indicator layers.According to the expert rating,the analytic hierarchy process(AHP)and fuzzy comprehensive evaluation(FCE)method were applied to evaluate the 10 typical farmland non-point source pollution control technologies comprehensively and quantitatively.AHP method and Spyder Software were used to calculate the index weight value.The results showed that the comprehensive weight values of ammonia nitrogen removal rate,TP removal rate,water quality purification efficiency,project operation cost,winter purification stability and landscape diversity index were the highest,which were the most important evaluation indexes in selecting the farmland non-point source pollution treatment technology for Liaohe River.The FCE method and Matlab software were used to calculate the index subordination degree and fuzzy comprehensive evaluation value.The results showed that ecological interception ditch technology was the best technology among process interception technologies with a fuzzy comprehensive index value of 3.8872;the constructed wetland technology was the optimal technology of the terminal treatment technologies with a fuzzy comprehensive evaluation value of 3.9304.This study provides a theoretical basis for selecting suitable farmland non-point source pollution control technology in Liaohe River,and also provides effective support for the evaluation of other similar pollution control technology and formulation of relevant policies.
