【 摘 要 】

Eastern Sichuan is an important ecological barrier in the upper reaches of the Yangtze River. Based on 1990, 1995, 2000, 2005, 2010 and 2015 Landsat TM / ETM image data, the dynamics change of land use is analysed by using remote sensing and GIS software. The trend of change measures the effect of the Grain to Green Projects in the study area. The results show that farmland was the main type of land, and building land had the most dynamic degree during the period of studying. Since the implementation of the Grain to Green Projects in 2000, the area of farmland has decreased and the patches have been fragmented. The area of forestland has increased and the connectivity of patches has increased. The shape of grass types has tended to be regular. At the same time, the overall landscape diversity has increased and the spatial layout has become increasingly regularized. This study provides a theoretical support for policy-making of environmental protection and management in Eastern Sichuan Region of Sichuan Province.
