中文摘要：

土地利用/覆被变化（LUCC）是影响陆地植被碳循环的重要因子之一.基于GIS和RS技术，利用遥感和气象等数据，并采用CASA（Carnegie Ames Stanford Approach）模型和植被枯损模型估算了皖江城市带植被的固碳密度，分析了2001-2010年皖江城市带LUCC所引起的植被碳储量的变化，结果表明：近10年来，皖江城市带土地利用变化较明显，使得植被生态系统碳库储量减少了3.55＆#215;105 t.具体表现在：林地碳储量增加了1.42＆#215;105 t，耕地碳储量减少了4.87＆#215;105 t，草地碳储量减少了104 t.皖江城市带各种植被类型中，有林地的固碳潜力最大，为437 g/m2；其次是耕地，为326 g/m2；草地最小，为218 g/m2. LUCC导致的耕地和草地减少，是皖江城市带植被碳储量减少的主要原因.

英文摘要：

Land use/cover change is an important factor which affects the carbon cycle of terrestrial vegetation.Based on GIS and RS technology,remote sensing data and meteorological data,and CASA model and vegetation such as low loss model,this paper estimates the density of vegetation carbon sequestration of Wanjiang City Belt,and an-alyzes LUCC caused by the change of the vegetation carbon in Wanjiang City Belt from 2001 to 2010. The results show that land use change of Wanjiang City Belt is so obvious that the vegetation ecosystem carbon reserves reduces 3.55＆#237;105 t Over the past ten years. Particularly speaking,carbon of woodland forest increases 1.42＆#237;105 t,carbon of cultivated land reduces 4.87＆#237;105 t,and the grass carbon reduces 104 t. As far asthe carbon sequestration potential,the forest is largest for 437 g/m2,followed by 326 g/m2 for agricultural land;the smallest is 218 g/m2 for grass-land. LUCC results in a decrease of farmland and grassland is the main reason for reducing the number of vegetation car-bon in Wanjiang City Belt.
