The value of terrestrial ecosystem carbon sequestration services has been widely recognized. Forests, grasslands and other ecosystems can store large amounts of carbon, which is the key to mitigating global climate change. The eco鄄 environment of the western region of Sichuan Province was greatly destroyed by the earthquake which had occurred in Wenchuan on May 12, 2008. One of the direct impacts is that the landscape was seriously damaged and the disturbed eco鄄 system released a significant amount of carbon dioxide because of sudden changes inland utilization and vegetation cover. Our goal was to use the maps of land use and land cover types and data of carbon reserves stocks in four carbon pools to estimate the amount of carbon stored in a landscape currently and the pre鄄seismic amount of carbon in the earthquake鄄hit areas, and then we have got a series of maps which can help us to conduct carbon management. Based on the geographical information system software of ArcGIS, this paper presented the evaluation index system to assess the carbon storage function of the earthquake鄄hit area, by calculating the density of carbon storage for four carbon pools (aboveground biomass, underground biomass, soil carbon and dead organic matter) in each grid. In addition, this paper also analyzed the spatial pattern of carbon storage function in this area. The results showed that the total carbon storage volume of the earthquake鄄hit
