摘　　要：针对密云县冯家峪镇9种典型森林类型,设置典型样地,开展乔木、灌木、草本、土壤和枯落物碳储量调查,并对增汇潜力进行分析。结果表明:1)冯家峪镇现有森林面积12 823.55hm2,总碳储量为692 141.73t;油松林的碳储量最高(195 806.52t),柞树林以144 831.77t次之,再次为落叶松人工林(74 597.60t)。2)冯家峪镇不同林分中,落叶松人工林的碳密度(72.02t/hm2)为最高,其次为油松人工林和刺槐人工林,分别为64.42t/hm2和62.87t/hm2,侧柏人工林的碳密度最低,为42.79t/hm2。在对总的碳密度的贡献中,乔木碳库和土壤碳库起着主要的作用。3)与全国森林植被碳储量平均水平(40.06t/hm2)相比,冯家峪镇森林通过合理经营其碳储量可增加潜力为166 400t。Based on field investigation,carbon storage and carbon sequestration were compared between nine different forest types in Fengjiayu Township,Beijing.As a result,the area of the forest in Fengjiayu township was 12823.55 ha and the total carbon storage was 692141.73t.The carbon storage for Pinus tabulaeformis forest was the greatest（195806.52t）,that of the oaks ranked the second（144831.77t）,and the Larix gmelini ranked the third（74597.60t）.The highest carbon storage per hectare was plantation of Larix gmelini（72.02 t/ha） and the lowest was plantation of Platycladus orientalis（42.79 t/ha）.The trees occupied high proportion of the gross carbon sink.Compared with the average of forest carbon storage in China,the forest carbon storage in Fengjiayu Township was 166400t.
