| 摘 要： | 土地利用/覆被变化是影响陆地生态系统碳储量变化的重要驱动因素。利用绥阳县2000年、2005年、2010年3期ETM/SPOT影像解译获得的2000—2010年土地利用变化数据,估算了该县土地利用变化对生态系统中植被碳储量的影响。结果表明:2000—2005年研究区耕地面积增加了22.87hm2,林地、牧草地分别减少了15.78,8.28hm2,植被碳储量2005年比2000年减少了2 945.11t;2005—2010年研究区耕地、牧草地分别减少26.28,4.09hm2,林地增加29.07hm2,植被碳储量2010年比2005年增加了1 786.17t。综上,该县植被碳储量总体呈减少趋势,且退耕还林还草、天然林保护工程和城镇建设用地增加等是影响该地区植被碳储量变化的重要因素。 |

| 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 2 945.11 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 1 786.17 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. |
