摘要
基于北部湾经济区的EOS/MODIS卫星遥感资料和2000年、2006年土地利用遥感解译结果,利用GIS技术,获取区域土地利用转移信息图、土地利用类型转移矩阵及植被净初级生产力时空变化图,计算植被碳汇变化量;根据区域土地利用与植被碳汇的时空变化特征,构建区域土地利用变化对植被碳汇的生态风险影响评价流程,获取区域植被碳汇的生态风险指数空间分布。
Based on the MOD17A3 data of NASA EOS/MODIS（Terra）and land use remote sensing data of Beibu Gulf Eco- nomic Zone in 2000 and 2006, GIS technology was used to obtain land - use transfer information map, land use change matrix and the change of vegetation carbon sequestration. This paper constructed the ecological risk assessment method of vegetation carbon sequestration according to land use and vegetation carbon sequestration change structure characteristic. It was used to get ecologi- cal risk index of vegetation carbon sequestration distribution over Beibu Gulf Economic Zone.
