Paper Abstract

Based on SPOT images and other geoscience data, this paper gets the land use and land cover information of Modern Agriculture Corridor from 2006 to 2008 by RS and GIS technology and makes analysis of land use changes in landscape ecology view. Then we build a quantitative evaluation model which select vegetation coverage as adjustment coefficient to monitor the changes of ecological services value. The results show that: In the aspect of landscape pattern index, the landscape heterogeneity of the region is increasing, the land use types become various, degree of landscape fragmentation has increased; woodland, farmland and construction land play a leading role in the dynamic changes of landscape. In the view of ecosystem service value, the total value of ecosystem services of Modern Agriculture Corridor from 2006 to 2008 are respectively 186, 188, 193 million Yuan, and the annual average rate is 2%; ecosystem qualities are different in different seasons, and quality in summer is best which has 33% contribution to the full-year value of ecosystem services; the average contribution rates of forest and waters ecosystems are the highest, respectively 37% and 33%; increase of woodland, grassland and water area is the main reason that enhancing ecosystem services.
