Measurement and Analysis of Environmental Cost for Land

Abstract

We select the Qinghai-Tibet Railway Project and Qiong Ming Expressway Project in China to carry out environmental cost, real economic cost accounting and cost-benefit analysis, and then make a comparative analysis of the two land use projects. First, we get the construction cost and environmental protection input cost of the two projects by looking up the database. Then we use our model to calculate the environmental cost and get the ratio of the environmental cost to the total input cost. Finally, we concluded that compared with the total input cost, the loss caused by environmental damage is enormous and we must take environmental protection into account when carrying out land use projects. From the point of view of the project planners and managers, according to the principle of minimization of environmental costs to design three feasible solutions, the scheme is designed referring to the resource weights obtained by AHP and the grey relational analysis and the resilience of ecosystems. The curves, which can reflect the cost effectiveness of the three schemes over time, are plotted. According to the principle of cost-benefit maximization, we select an optimal scheme, and give project planning advice to project planners and managers. Then, considering the sustainability of environmental damage, especially some large projects, we analyze the Qinghai-Tibet Railway project. Based on the original model, we analyze the environmental cost caused by noise pollution and human activities, and give the curve of environmental cost with time. It is found that the fitting effect is very good when the curve trend is fitted with the actual situation, which also proves the validity of the model. Finally, we analyze the advantages and disadvantages of our model and the subsequent improvement work.
