摘　　要：气候变暖是人类面临的十大生态问题之首,而人类社会大量排放二氧化碳等温室气体形成的温室效应则是气候变暖的根源。因此,如何控制二氧化碳气体的排放量、降低大气中二氧化碳的浓度越来越成为国际社会关注的焦点。而森林在吸收、固定二氧化碳方面扮演着极其重要的角色。本文研究的初衷就是要对森林的这一作用做出评价。区域森林植被碳贮量的估算是研究全球碳贮量的基础,本研究基于湖南省森林资源清查资料,结合生物量测定数据,估算了湖南省针叶林乔木层的碳贮量和碳密度,探索森林碳汇价值评价方法。Climate warning ranks the top of ten ecological problems that human beings have to face. The over-emission of carbon dioxide （ CO2 ） and other heat-trapping gases is at the root of the greenhouse effect. Therefore, it has been becoming a focus that how to control the release of the carbon dioxide and decrease the density of the carbon dioxide in the atmosphere. Obviously, forests play an important role of absorbing and fixing carbon dioxide. The original intention of the research is just to evaluate the role of the forests. Research of carbon storage of regional forest vegetation is a foundational work to understand the carbon storage at global level. The carbon storage and density of conifer forest stratum in Hunan Province were estimated based on the data from the fourth forest resource inventory and the measured biomass equation of different forest categories, probing the method of the evaluation of the forest carbon sequestration
