Land cover change is an important part of ecosystem change and driving factors. In the impacts of the global change and the ecological construction in the 2000s,the land cover of China has changed significantly. Monitoring and analysis of this change not only can support China carbon source/sink evaluation and assessment of carbon budget, but also provide the basic data for the ecological environment evaluation. Supported by object-oriented classification technology, the land cover data of China ( ChinaCover) in 2000 and 2010 have been produced using Landsat TM/ETM and HJ-1 satellite data of 30m resolution, combined with a large number of data of field investigation. At the same time, vegetation coverage data has been produced using the dimidiate pixel model with resolution of 250m. This study has analyzed the change of China land cover changes based on the land cover data and vegetation coverage data of 2000 and 2010. Results have showed that: there have been a total of 19* 10~4km~2 land cover changes,accounting for about 2% of the China land area. The areas of woodland and artificial surface have been increased ; the areas of grassland, wetland and cultivated land have been decreased. The rapid increase of artificial surface and the mass reduction of cultivated land has been the main trend of land cover changes. The area of artificial surface has increased by 28. 7%,while the area of cultivated land has decreased by 4. 8x 10~4km~2, 2. 7% lower than in 2000. The conversion areas of cropland to artificial surface have been mainly concentrated in Eastern China; the conversion areas of cropland to forest and grassland have been mainly distributed in the areas where the Regulations on Restoring Farmland to Forest" has been carried out; Arable land expansion has been mainly occurred in the Sanjiang plain and the Xinjiang oasis. The vegetation coverage changes of forest, shrub and grassland have showed an overall upward trend in 2000s. There have been 47. 3%,58. 8% and 55. 6% of the forest, shrub and grassland vegetation cover has been improved. But forest quality has had the trend of degradation in the Wenchuan earthquake-stricken area, Hengduan Mountains and Wuyi Mountain areas; shrub vegetation coverage has declined around the Tarim basin, eastern Tibet Plateau, Taihang Mountain, and Luliang Mountain areas ; grassland has been deteriorated in central Inner Mongolia,southwestern Tibet Plateau,southern Tianshan and Hulun Buir.
