基于GIS的森林植被碳储量、碳密度分布——以酉阳土家族苗族自治县为例

Distribution of Forest Carbon Storage and Carbon Density Based on GIS——A Case of Tujia and Miao Autonomous Counties in Youyang

结合酉阳林地资料和实地调查数据,利用生物量-蓄积量转化模型,运用ArcGIS9.3软件,对酉阳林地植被碳储量和碳密度分布进行研究,对县域内石漠化和非石漠化、碳酸盐岩和非碳酸盐岩的碳储量和碳密度的差异给出精确的数据,并对酉阳森林经营管理提出建议。

Combining the forest information with survey data of Youyang, using the localized model between biomass and volume, the distribution of forest vegetation＇s carbon storage and carbon density was studied with ArcGIS9.3. Data about the carbon storage and carbon density in carbonate and non-carbonate districts were provided, as well as the density rocky desertification and non-rocky desertification areas and suggestions on management in Youyang were also put forward.
