为了研究滇中地区主要灌丛生物量空间分布的格局及特征,采用收获法,选择滇中地区10个县市共8种典型的灌丛植物进行分析,探究其地上生物量与地下生物量在空间分布上的关系。结果表明:滇中地区灌丛群落的地上生物量介于47.17~68.94g/m³之间,地下生物量介于49.67~72.10g/m³之间,根冠比(R/S)介于0.87~1.27之间。滇中地区灌丛群落与物种的地上和地下生物量的拟合的斜率分别呈异速分配关系,植被的根冠比较其它植被类型的根冠比更小,说明滇中灌丛植被将更多的生物量分配到地下部分,以实现对滇中地区环境的适应。

In order to explore the spatial distribution pattern and characteristics of the main shrub biomass in central Yunnan,we used the harvesting method,and more than 8 typical shrub plants in 10 counties and cities in central Yunnan were selected for analysis to explore the spatial distribution of above-ground biomass and under-ground biomass to infer the characteristics of the spatial distribution pattern.The results showed that the above-ground biomass of shrub communities in central Yunnan was between 47.17~68.94g/m³,the underground biomass was between 49.67~72.10g/m³,and the root-shoot ratio(R/S) was between 0.87~1.27.The slope of the above ground biomass and the below ground biomass of the shrub community and the species in central Yunnan area showed the relation of allometric biomass distribution,and the root-shoot ratio of root to compare other types of vegetation,therefore,the vegetation in this area will put more biomass into the underground part to achieve adaptation to the environment in central Yunnan.
