Study on Rural Environmental Quality Comprehensive Evaluation Model

Abstract

The rural environmental quality comprehensive evaluation index system is established from three aspects, the quality of rural living environment, the quality of rural ecological environment and the rural environmental resource availability. Analytic hierarchy process (AHP) is used to determine the weight of each index. Remote sensing(RS), geographical information system(GIS) and the composite index evaluation method are used to establish all levels of index evaluation model. And the quality of the environment in rural areas is divided into four categories. This paper takes a county as a case, and uses established models and the corresponding technology to conduct confirmation analysis and discussion with the county's environmental quality. The evaluation results are basically consistent with actual situation of the county, which indicating that the established index system and model for the comprehensive evaluation of environment quality in rural areas are feasible. The comprehensive evaluation model can provide a scientific basis for the rural environmental management and environment comprehensive improvement planning.
