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2453900h m 2增长到本世纪初的4842600h m 2(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322.65T gC ;1977~1981期间为431.15T gC ;1984~1988期间为469.30T gC;1989~1993期间为499.25T gC ;1994~1998期间为555.57T gC ;1999~2003期间为639.32T gC 。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。关键词:竹林;生物量;碳密度;碳储量
