Ecological cost assessment about different scales project

Abstract

Many project decision makers do not consider the value of ecosystem services in the decision-making process. This article addresses this issue which is to use the life cycle method to select relevant indicators. And use the Analytic Hierarchy Process (AHP) to establish an ecological cost assessment model by MATLAB, EXCEL and other software to calculate ecological costs of project. Finally, based on the results of the model, provide advice to project decision makers. The characteristics of this paper is monetizing the impact on the ecological environment and using the life cycle method to establish a complete and coordinated indicator system to make the model more accurate and easier to calculate. First, we conduct a full life cycle analysis of the project construction to obtain environmental impact indicators in each stage. Then use the AHP method to analyze the indicators, calculate indicator weights by MATLAB, and verify the validity of the AHP model; finally, we adopt different cost analysis methods according to the categories of indicators, including the energy analysis method, the virtual governance method, the market value method and so on. Finally, we calculate the ecological cost of the project. After the model is built, we collect data by understanding the land planning bureau report, the engineering design department plan, and then evaluate the ecological costs of large projects and small projects. According to the results of the model calculation, the land planner decision makers are proposed to rationally plan land resources and reduce the waste of ecological resources.
