摘　　要：文章采用RS和GIS技术,通过构造北京市土地利用结构转换矩阵分析了1990-2010年的碳排放效应,得出结论是:第一,耕地的转出量最大,主要转向建设用地、林地和草地,导致的碳排放变化量也最大。第二,草地的转出量居第二位,主要转向林地和耕地,收支相抵最终使碳汇增加。第三,林地虽转出绝对量较大,但3/4以上没有发生转移,保持了北京市碳汇量的稳定。第四,水域转出的绝对面积最小,主要流向耕地和建设用地,也增加了碳源。第五,建设用地转出的面积较小,主要转向耕地、草地和林地,相应引起碳排放减少;但其转入面积最大,使其成为碳源增加的决定性地类。第六、未利用地主要转向建设用地和林地,导致碳源增加,其净碳排放功能却存在不确定性。By using the technique of RS and GIS based on the LUCC, this paper analyzed carbon emission effects after built the transition matrix of land use structure in Beijing in 1990-2010 year. The results show that： the roll-on areas of cultivated land were the biggest, this led that the variable quantity of carbon emission was also the biggest, while the roll-in of cultivated land derived from construction land, grassland and forest., the roll-on areas of grassland were the second place, this led lastly the growth of carbon emission after making ends meet, while the roll-in of grassland derived from cultivated land and forest. The roll-on absolute areas of forest were the bigger, but 3/4 of it had not shift, so this maintained the stability of carbon absorption. The roll-on absolute acreage of waters area were the smaller, this also led the growth of carbon emission. The roll-on areas of construction land were lesser, this corresponding led to decrease of carbon emission, but the area of its roll-in was the biggest, this led that it became the critical land types of carbon emission growth. The roll-on acreage of unutilized land, which led to growth of carbon source, and its function of net carbon emission yet existed uncertainty.
