Measurement of Ecological Capital of the Ecosystem based on Remote Sensing Data

Comprehensive evaluation on the conditions of ecosystem is important to protect regional ecoenvironment. The paper is mainly based on the data set of remote sensing and climate factor to calculate the ecological capital of ecosystem in Yunnan province. The results showed that ecological capital of the province from 2005 to 2008 was 225.02 billon yuan RMB, 207.78 billon yuan RMB, 191.11 billon yuan RMB and 195.48 billon yuan RMB respectively. Total and unit ecological capital showed a decreasing trend. The spatial distribution of ecological capital per area took on a pattern that the west was higher than the east and the south was higher than the north, ecological capital of forest, shrub and grassland, which constituted the main body of ecological capital took up a percentage of 79.94%, 80.52%, 81.44% and 80.48% respectively to the total in the province from 2005 to 2008.
