The Change Monitoring of Natural Capital of Beijing Based on Remote Sensing-a case study with water and green space

The economic value of natural resources and natural environment can be described by natural capital. Based on the example of the change of water and green space within the fourth ring road of Beijing from 1983 to 2002, this paper presents the quantitative research on the change of natural capital by the means of remote sensing. And this paper explores the dynamic change of water and green space as natural capital, and assesses the economic loss from the viewpoint of natural capital. Then this paper analyzes by each (City proper, Haidian, Fengtai and Chaoyang). Finally, conclusions are drawn that there is a decrease of 18.72% of water and a decrease of 23.33% of green space. The largest change happens in Haidian. Also the distribution, types and functions of natural capital have changed at different levels. Finally the factors which cause the change are presented. Also some solutions are put: forward.Geosciences, MultidisciplinaryRemote SensingImaging Science & Photographic TechnologyEICPCI-S(ISTP)
