As the important terrestrial ecosystem, forest plays an important role in dealing with global warming. The forest carbon storage,which refers to the quantity and its ability to absorb or store C02, has a strong effect on reducing greenhouse gases density in the atmosphere and mitigating the global warming. Nowadays, in China there are mainly three measurement methods： Stand Volume Method,Biomass Method and Checklist based on the Biomass Method and Stand Volume Method. The conversion factor of biomass-carbon is the fixed value or experimental value. This paper mainly employs biomass measurements. Community biomass is not only an important index to evaluate the productivity and the potential productivity of forest plant community, but also a quantitative basis to study the organisms, structure and process functionality of the forest ecosystem. Based on the two study objects-Youhua and Zhubei natural secondary deciduous broad-leaved forest in Qingyang County of Anhui Province, the research selects two lands with different altitudes, exposures to measure the tree layer biomass with the mean tree method. On this base,it analyzes different deciduous broad-leaved biomass and calculates the forest car- bon storage.%森林是重要的陆地生态系统，在应对全球气候变化中扮演着重要的角色。森林碳汇指森林等吸收并储存CO：的多少，或者吸收并储存CO2的能力。森林碳汇对降低大气中温室气体浓度、减缓全球气候变暖具有十分重要的作用。目前国内有关森林碳汇的计量方法主要有蓄积量法、生物量法和基于蓄积量法、生物量法的生物清单法。对于生物量一碳储量转换因子多采取固定值或实验值。该文采用生物量法计算碳汇。群落生物量是评价森林植物群落生产力高低和潜在生产力大小的重要指标，也是研究森林生态系统生物群落、生产结构及功能过程的定量依据。此项研究以安徽省青阳县酉华和朱备2个研究地天然次生落叶阔叶林为研究对象，选择2块不同海拔和坡向的大样地，采用平均标准木法测定乔木层生物量。在此基础上，分析不同落叶阔叶林林分生物量，进而计算出其森林碳储量。
