Abstract:: Land use/cover change is the main driving factor for the change of ecosystem carbon storage. In this paper, impacts of land use change on the vegetation carbon storage in Suiyang County from 2000 to 2005 and from 2005 to 2010 was stuided based on land use maps of 2000, 2005, 2010, which were interpreted from the ETM/SPOT images. The conclusions were drawn as follows: The area of forestland and grassland decreased by 15.78 hm² and 8.28 hm², respectively, during 2000-2005. The area of cropland increased by 22.87 hm² during 2000-2005, the vegetation carbon storage decreased by 2945.11 t during 2000-2005. The area of cropland and grassland decreased by 26.28 hm² and 4.09 hm², respectively, during 2005-2010. The area of forestland increased by 29.07 hm² during 2005-2010. The vegetation carbon storage increased by 1786.17 t during 2005-2010. The results showed that the total vegetation carbon storage was a decline trend. Returning farmland to forestland, natural forest protection and urban construction were important factors conntribution to the vegetation carbon storage in this region.
