Application of Fuzzy Comprehensive Evaluation Model Based on Analytic Hierarchy Process for Rural Drinking Water

Twelve evaluative indicators are selected in three aspects: water quality, water quantity as well as water supply. The weight of each indicator is determined by Analytic Hierarchy Process. The fuzzy comprehensive evaluation model is constructed on the basis of fuzzy evaluation theory and Analytic Hierarchy Process. The distribution maps of security condition about rural drinking water in Henan province are obtained by the way of Geographic Information System. All the researches indicate that the condition of water quality of rural drinking in Henan province is unsafe, water quantity is security, water supply and overall condition are basic security. They have reflected the actual condition of rural drinking water in Henan province to some degree. Therefore, we can make it clear that this method is reasonable even reliable, the results coming out of which are believable. After all, it has provided an inventive method for security evaluation on rural drinking water.
