摘要
为了解喀斯特环境下的生物量,本文采用收获法对贵州南部茂兰喀斯特森林群落进行测定。结果表明:群落总生物量为146.319—190.918t/ha。其中乔木层地上部分89.198t/ha,灌木层5.747t/ha,草本层0.275t/ha,枯枝落叶层6.500t/ha。群落乔木层之胸径与其生物量,在树种间有较为显著的相关关系。与其它类型森林比较,喀斯特森林为低生物量森林。
To understand the biomass of forest in the karst envirnment, the harvest method has been used for determining the karst forest community in Maolan located in the south of Guizhou, China. The forest studied is a mixed evergreen and deciduous forest in the humid mid-subtropical climatic zone, It was found that the forest has a total biomass of about 146.319 to 190.918 t/ha and the oboveground plant biomasses of arborous layer, brush layer, herb layer and litter layer are 89.198, 5.747, 0.275 and 6.500 t/ha, respectively. The correlation coefficient (r) between DBH and biomass is over 0.900.
