摘 要:以四川省绵阳市游仙区农村安全饮水工程为例,借助因子分析法与层次分析法构建了基于用户需求的农村安全饮水工程契合度评价模型。其中,二级指标对于一级指标的权重系数由因子分析提取公因子的贡献率确定,三级指标对于二级指标的权重系数由层次分析的主观权重和因子分析的客观权重最终确定。研究表明,水费定价收费标准的合理性、饮水资源获取的便捷性、工程建管质量的可靠性成为众多影响契合度因素中的主要因素。模型计算结果与实际调查结果大致吻合,这说明,考虑用户需求条件下的契合度评价模型对于指导农村安全饮水工程评价工作具有一定的适用性。According to the rural safe drinking water projects in Xianyou district of Mianyang city in Sichuan Province,a fitness evaluation model for the safe drinking water projects in the rural areas based on the user demand was established using the methods of factor analysis and analytic hierarchy process(AHP).The weight coefficients of the second-grade indexes with regard to the first-grade indexes were determined by the contribution rate of the common factor extracted from factor analysis,and the weight coefficients of the third-grade indexes with regard to the second-grade indexes were determined by the subjective weight from AHP and objective weight from factor analysis.The results showed that the reasonableness of water fee standard,the convenience of access to drinking water resource,and the reliability of quality of engineering construction management are the main factors affecting the fitness.The model results were similar to the actual survey results,which suggested that the fitness evaluation model based on the user demand is applicable to guide the evaluation of safe drinking water projects in the rural areas.
