【摘要】 竹林是陆地生态系统中一个重要植被类型。中国是世界竹林分布中心,有39个属500多个竹种,竹林面积由20世纪50年代的2453900hm2增长到本世纪初的4842600hm2(未计入台湾数据),增加了97.34%。调研20世纪80年代以来有关中国(竹林)的面积、生物量、碳密度、土壤有机碳等要素的研究成果,经统计分析得出中国竹林的平均单位面积生物量、平均单株生物量、土壤有机质含量及碳密度。在此基础上,依据过去6次全国森林资源连续清查的相关数据资料,计算出过去50a中国竹林碳储量及其变化。结果表明,我国竹林碳储量在过去50a呈增加趋势,其中1950～1962期间为322.65TgC;1977～1981期间为431.15TgC;1984～1988期间为469.30TgC;1989～1993期间为499.25TgC;1994～1998期间为555.57TgC;1999～2003期间为639.32TgC。越到后期增加越快。预期随着中国森林面积的增加,竹林碳储量仍将继续增加。更多还原

【Abstract】 Bamboo stand is one of important vegetation types in terrestrial ecosystem. China is located in the central distribution region of the globe. There are more than 500 bamboo species of 39 genera. The area of bamboo stand in China has been increasing from 2453900 hm2 in 1950s to 4842600 hm2 in early this century,increased by 97.34%. Estimating the carbon stock change in bamboo stands is therefore meaningful. The data for area,biomass,carbon fraction and soil organic carbon (SOC) of bamboo stands in China were collected from published literatures. Carbon stock and carbon stock changes in living biomass and soil organic matter of bamboo stands in China in last 50 years were estimated based on the collected data and the area of bamboo stands and the number of bamboos derived from China’s National Forestry Inventory that were conducted once every five years. Our estimation indicates that the carbon stocks in both living biomass and soil organic matter in bamboo stands have been increasing since 1950s. The estimated carbon stock is 322.65 TgC for inventory period 1950-1962,431.15TgC for 1977-1981,469.30TgC for 1984-1988,499.25 TgC for 1989-1993,555.57TgC for 1994-1998 and 639.32TgC for 1999-2003. With the increasing forest area in China,carbon stock in China’s bamboo is expected to continuously increase.更多还原
