摘　　要：农村生活污水处理工艺优选是农村生态环境保护的重要基础工作。针对农村生活污水处理方案多属性、多指标的特点,克服人为主观因素的影响,采用主观赋权法(AHP)和客观赋权法(熵权法)相结合确定组合权重,建立了改进的熵权TOPSIS模型。应用该模型对北京市农村生活污水的5种常用处理工艺进行优选。结果显示该模型计算简便,结果客观,为农村生活污水处理技术示范推广提供了决策分析工具。The optimization of rural sewage treatment technology is the basis for the protection of rural ecological environment. Ac cording to the multi-attributes and multi-indexes feature of rural sewage treatment technology, this paper uses subjective weight （AHP method） and objective weight （entropy value method） to determine combinatorial weights to overcome the influence of subjec tive factors, and sets up the improved entropy weight TOPSIS model, which is applied to the optimization of five common rural sew age treatment technologies. The results show that calculation of this model is simple, the results are objective, and the model can serve as the decision analysis tool for the demonstration and promotion of sewage treatment technology in rural areas.
