Pollution Classification and Comprehensive Treatment of Environments in Villages and Towns in Multi-dimensional Perspective

On the basis of sorting out main sources of pollutants in villages and towns，pollutions were classified from different dimensions and main characteristics were analyzed.Pollution factors in villages were identified and classified，and a technical index system for environmental pollution classification was constructed.Combined with classification of water and soil relations in China and classification of villages and towns，classification method of environmental pollution in villages and towns was proposed.The main laws and policies for construction of livable villages in China were sorted out，and on this basis，technical paths and models of pollution control were analyzed.This research could provide decision-making reference for formulation of environmental governance policies and supporting measures.
