LUCC是影响陆地植被碳循环的重要因子之一。采用2000、2005和2009年3期遥感影像解译及运用GIS技术提取芜湖市2000-2009年的土地利用变化数据，根据前人对植被NPP的研究成果，计算芜湖市土地利用变化对生态系统中植被碳储量的影响。结果表明：在2000-2005年，耕地大量转化为林地、草地大量转化为耕地等使其植被碳储量净增加了4．43×10^3-22．14×10^3t；2005年-2009年，林地大量的转移为耕地、建筑用地，耕地转为水域、建设用地等使其植被碳储量净减少了72．34×10^3-289．38×10^3t。研究结果显示，芜湖市植被碳储量总体呈减少趋势，且林地是影响芜湖市植被碳储量的主要因素。%Land use/cover change is an important factor which affects the carbon cycle of terrestrial vegetation. Using GIS technology to obtain data of land use change in Wuhu from 2000 to 2009 and based on data from remote sensing TM imageries in 1980,1990 and 2005, this paper calculates the change value of vegetation carbon storage caused by land use change with the meth- od supplied by the vegetation NPP research of predecessors. The main results are as follows： The vegetation carbon storage in- creased 4. 43×103 -22. 14×103t in 2000 -2005, because a lot of farmland transformed into forest land and grassland converted into farmland. The vegetation carbon storage decreased by 72. 34×103 -289. 38×103t, because of land use change during 2005 -2009. The results show that the total vegetation carbon storage presents a decreasing trend and the main factor affecting vegeta- tion carbon storage is woodland.
