摘要
本文采用收获法对贵州中部喀斯特灌丛群落的生物量进行测定。喀斯特灌丛群落的总生物量在２４．５５９３ｔ／ｈａ至４５．６７４６ｔ／ｈａ之间，其中地上部分约１４．２３６７ｔ／ｈａ，地下部分约１３．３１７７ｔ／ｈａ。不同群落类型其生物量存在一定差异。生物量在群落的垂直空间上，集中分布于近地表空间；在器官分布上则主要集中于根和茎枝。文章还对生物量与环境因子的相关性进行了分析。
The authors determined the biomass of karst scrub community in the central region ofGuizhou Province,SW China using harvest method.The karst scrub community is found tohave a total biomass of from 24.5593t/ha to 45.6746t/ha,of which 14.2367t/ha are aboveground and 13.3177t/ha are under ground.There are some differences in biomass for vari-ous scrub community. In distribution biomass concentrates near ground surface in terms ofvertical space of community,and in roots and stems in terms of plant’s physical organ. Acorrelation between biomass and environmental factors is analysed.
