Abstract: The paper aims to clarify the specific meaning of evaluation indicators for rural drinking water safety, and to discuss the existing quantitative evaluation methods. Rural drinking water safety problems are characterized by fuzziness, dynamics and extensiveness. In order to establish a complete evaluation index system which is consist with local reality, the four indicators such as water quantity, water quality, convenience and guarantee rate should be further elaborated and standardized, so to comprehensively evaluate the current situation of drinking water safety in rural areas. The determination of index weight is a key and difficult point in quantitative evaluation of rural drinking water safety. Weight determination methods can be divided into subjective weighting method, objective weighting method and subjective and objective combination weighting method. Both subjective and objective weighting methods have their own advantages and limitations in the multi-index comprehensive evaluation of rural drinking water safety. Optimizing the combination of subjective and objective weighting methods is one of the main research directions in determining the weights of evaluation indicators of rural drinking water safety.
