Abstract

To some extent, land use project implementation influences ecosystem. Although these projects may seem inconsequential to the total ability of the biosphere’s functioning potential, cumulatively they are causing environmental degradation, thus imposing some environmental costs on land use projects. In order to take into account the impact of environmental degradation in land use project costs, our ecosystem service evaluation model is established to assess environmental costs and obtain the true economic costs of land use projects. The ecosystem of the land use project region is divided into 7 types. Furthermore, the ecosystem services are classified into 6 parts. We evaluate ecosystem services of various land use types and obtain the total value by adding these ecosystem services. The environmental costs of land use projects can be calculated as the absolute value that ecosystem services before and after the land use project implementation minus each other. The true economic costs is the sum of environmental costs and build costs.Last, we studied the effect of time on the model. Take the Three Gorges Reservoir Area (Chongqing Section) as an example. We find that the value of ecological services will decrease over time in a certain period of time, and will also increase the real economic cost of land use projects.
