摘　　要：基于海南省五指山市2008年森林资源一类清查数据,利用空间误差模型(SEM)分析森林碳储量与林分因子、地形因子之间的关系和森林碳储量的空间分布,以期为五指山市森林管理规划提供相关信息。结果表明:五指山市森林碳储量的空间分布具有空间自相关性;文章所选的林分因子、地形因子都对森林碳储量的空间分布有显著影响,其中,郁闭度是最主要的因子。SEM可以很好地解决模型残差的空间自相关性。由模型的预估结果可以看出,森林碳储量的空间分布整体差异不大。Based on the data Wuzhishan Forest Resource Inventory collected in 2008, by using the SEM, the relationship between forest carbon storage, stand factors and topographic factors, the spatial distribution of forest carbon storage in Wuzhishan city were analyzed in order to provide useful information for forest management planning of the area. The results show that the distribution of forest carbon storage in Wuzhishan city had spatial autocorrelation; and the selected stand factors and topographic factors had appreciable impact to the spatial distribution of forest carbon stocks, of them the canopy density was the most important factor; SEM can solve the model residuals problem of spatial autocorrelation. The predication of model shows that there were not significant spatial differences in distribution of forest carbon storage.
