Study on Evaluation System of Green Landfill Based on Life Cycle —— Illustrated by the Case of Hangzhou Tianziling Landfill

Abstract Recently, the environmental problems of Hangzhou Tianziling Landfill have brought great troubles to the lives of nearby residents. Landfill is the main method of garbage disposal. The requirement of green environment protection about landfill is becoming higher and higher, and the way in which the important indicators affects the environmental of landfill has also followed by lots of interest. In this paper, on the basis of the whole life cycle evaluation index system of landfill, the evaluation index of green landfill is increased, and then the evaluation index system of green landfill based on the whole life cycle is constructed by using hierarchical analysis method. Using Hangzhou Tianziling Landfill as a case to establish the practical model; establishing the hierarchical index weight and calculating it. Comparing the weight of each index shows that the proportion of odor concentration in environmental protection index is largest, and finally the comprehensive evaluation score of Hangzhou Tianziling Landfill based on life cycle is obtained.
