Ecological Capital Assessment and Analyses of Dynamic Changes in Arid Area

Form the macroscopical-ecology point of view, base on remote sensing measure of region ecological capital evaluation's character, consider the possibility and reliability of acquire the data, we developed regional ecological capital assessment index in remote sensing measure. The paper calculate the total ecological capital from nine kind of ecological value. Base on the research achievements of the methodology of calculating per unit area ecological service value and the support of RS, GPS and GIS, the RS-based quantitative measurement of assessing the ecological capital developed by using the Landsat TM data, CBERS satellite data, meteorological data, MODIS satellite data and ecological data. We divided the study site to four ecological district and assess the ecological capital quantitative. A case study on the Spatial Analysis of the assessment of ecological capital in Changji Hui autonomous in 1990, 1995 and 2003 is carried out. Maps of the spatial distribution of ecological capital in the study area are charted, and the characteristics of the spatial distribution of ecological capital are analyzed.
