摘　　要：农业面源污染是导致洱海富营养化的重要污染源,本文建立了考虑环境、经济和生态效益的面源污染控制技术评价指标体系,评价指标包括总磷、氨氮及化学需氧量去除率、建设及运行成本、技术稳定度、管理方便度和生态协调性等。同时,应用层次-灰色关联分析法,在洱海面源污染控制技术初筛的基础上,对备选技术进行综合关联度评判,获得最优方案。评价结果表明:生活污水污染控制备选方案中,土壤净化槽最优;在畜禽养殖污染控制备选方案中,基质化栽培最优;在农业径流污染控制方案中人工湿地最优。Agricultural non-point source pollution is probably the largest source of water pollution, contributing to eutrophication of Lake Erhai. In this paper, a non-point source pollution control technology evaluation index system considering environmental benefit, economic benefit and ecological benefit is established, and the indicators include TP removal efficiency, COD removal efficiency, ammonia removal efficiency, construction cost, operating cost, technology stability, management easiness degree and ecological coordination degree. At the same time, on the basis of non-point source pollution control technology choice in Lake Erhai, the hierarchy-grey correlation analysis method is used to evaluate the comprehensive correlation degrees of alternative technologies and obtain the optimal solution. The result shows that in the sewage pollution control alternatives, soil purification tank is the optimal scheme. In livestock and poultry breeding pollution control ahernatives, substrate cultivation technique is the optimal. In farmland pollution control schemes, constructed wetland is the optimal.
