依据“源头—过程—末端”防控体系对13种常见的农村水资源保护措施进行分类,在此基础上,建立AHP评价模型,根据影响水资源保护措施适宜性的13个指标对各项措施进行适宜性评价.结果表明:污染物去除率、出水水质、建设成本及运行维护这4个因素具有较高权重值,应在实际运用中优先考虑.源头控制措施中保护性耕作与“一池三改”技术可以作为首选措施;在过程控制措施中,土地处理技术措施具有较好的适宜性;在选取末端处理措施的时候,必须优先考虑温度及建设成本的影响.

13kinds of common water resources conservancy measures were classified into three (source, process and terminal) control systems. In addition the measures of each category were evaluated by the Analytic Hierarchy Process method as well as 13 factors of the technical suitability and economic feasibility of water conservancy measures. The results indicated that pollutants removal rate, effluent water quality, cost of construction, operation, and maintenance should be given priority in real world applications they had the higher weight value than other indices. Conservation tillage and ‘One biogas pond with improvements of washroom, kitchen and sty’ could be used as the preferred methods in source control. Moreover, land treatment technology was more suitable than other process control methods. External temperature and construction costs must be considered when selecting terminal control methods.
