摘　　要：基于海南省尖峰岭林业局2014年遥感影像数据和2010年森林资源二类调查数据,对尖峰岭林业局天然林进行抽样随机布点,采用生物量转换因子连续函数法估算碳储量,并利用造林成本法计算其碳汇价值。结果表明:1碳汇价值的空间分布呈西北低东南高的趋势,主要受尖峰岭林业局西北高东南低的地势影响,海拔越低的区域林分的整体生长状况越好。2尖峰岭林业局天然林碳汇价值与郁闭度存在较高的相关性,即郁闭度高的区域其碳汇价值较大,反之则较小。3基于2010年森林资源二类调查数据估算出尖峰岭林业局天然林碳汇总价值约为3650万元与使用克里格插值法估算出的3850万元不存在显著差距,说明针对尖峰岭林业局天然林碳汇价值的克里格插值效果很好。4利用克里格插值法客观地预测森林碳汇价值,能直观地反映出森林碳汇的分布情况,具有准确、快速、无破坏且省时省力等优点。Based on remote sensing data of Jianfengling Forestry Bureau of Hainan Province in 2014 and combining with the investi- gation data of two types of forest resources in 2010, we will take random sampling distribution of natural forest in Jianfengling Forestry Bureau;we will estimate carbon storage by using the method of biomass conversion factor continuous function method and calculate the value of its carbon sink by using the method of afforestation cost. The results demonstrate that （~）the trend of spatial distribution of carbon sequestration value is low quantity in northwest and high quantity in southeast, which is mainly caused by topography effect of Jianfengling Forestry Bureau where altitude of northwest is high and altitude of southeast is low, so the lower altitude areas stand, the better the regional forest grow. （2）Jianfengling Forestry Bureau natural forest carbon sequestration value and canopy has a high correlation,which demonstrates that high canopy density region has larger carbon sequestration value and vice versa. （3）Based on 2010 forest resource second class survey data,we will estimate carbon natural forest in Jianfengling Forest Bureau summary worth about 36. 5 million yuan with the use of Kriging interpolation method to estimate the 38.5 million yuan does not exist significant gaps, aiming at Jianfengling forestry＇s good natural forest carbon sequestration value of Kriging interpolation effect. （4）Using GIS objectively to evaluate forest carbon sink value, it can reflect the distribution of forest carbon sink visually and the advantages of accurate ,fast, no damage and save time and effort.
