摘要
利用标准样方法研究毛竹林碳含量和碳储量以及空间分布。研究表明，毛竹地上部分各器官的含碳率波动范围为428．3730—480．0790∥kg，平均为459．5461g／kg，其中竹叶的含碳率最低，竹秆的含碳率最高。毛竹地上部分碳储量为28．98t／hm^2，地下部分碳储量为14．27t／hm^2。从各组分分布来看，竹秆占总碳储量的51．84％，竹枝占10．27％，竹叶占4．90％，地下部分占总碳储量的33．00％。毛竹林生态系统总碳储量为173．93t／hm^2，其中土壤层碳储量为91．95t／hm^2，占总碳储量的67．44％。毛竹林地上部分年固定碳量为8．28t／（hm2·a），相当于同化二氧化碳的量30．36L／（hm2·a）。
Content, storage and spatial distribution of carbon in Phyllostachys edulis stands were studied by means of sample plot. Carbon content of aboveground in different P. edulis organs were 428. 373 0 - 480.079 0 g/kg, average value was 459. 546 1 g/kg. Carbon content was the lowest in leaf, and was the highest in stem. Carbon storage of aboveground in P. edulis was 28.98 t/hm2, and that of underground was 14.27 t/hm2. Carbon storage in stem, branch, leaf and underground accounted for 51. 84%, 10.27%, 4.90%, 33.00%, respectively. The total carbon storage of P. edulis ecosystem was 173.93 t/hm2 , of which carbon storage of soil was 91.95 t/hm2 accounted for 67.44%. The total annual carbon fixation of aboveground in P. edulis forests was 8. 28 t/（ hm2 · a） , corresponding to CO2 30.36 t/（ hm2 ·a）.
