考虑环境代价的土地利用价值评估

Land resource is finite and precious in the development of society .Environment costs which contribute to human welfare, both directly and indirectly, are often neglected in the evaluation of land use. This paper ，from the view of the land use，presents a study of value assessment including both environmental costs and economic value. By multiplying a set of ecosystem services with a set of corresponding shadow prices which are based on published studies and a few original calculations, the current environment costs (EC) can be estimated. Also the economic value (EV) produced by land use is calculated in this paper. Then functions assessing the real value of land use can be obtained by considering the environment costs and economic value. Application of this study on a land use example is shown lately. At last, how to achieve the sustainable development with the finite land resource is discussed.
