摘  要：
基于Moran’s I指数和GIS地统计插值方法研究浙江省森林土壤有机碳密度(SOCD)的空间自相关性及其分布特征,并采用线性回归方程分析影响因素对SOCD的作用。结果表明:浙江省森林土壤0～30 cm层次SOCD为71.2 t hm-2,较全国土壤平均碳密度低;全局Moran’s I=0.176,显示显著空间自相关性;浙江省森林SOCD呈现自西南向东北梯级递减趋势,表现为三条平行的带状分布;优势树种、坡位、龄组、海拔、灌木覆盖度、灌木平均高、平均年龄与SOCD呈极显著正相关关系,坡向与SOCD呈显著正相关关系,草本覆盖度与SOCD呈极显著负相关关系,草本平均高影响不显著;影响因素作用于SOCD14.9%的变异。

摘  要：
With the aid of the Moran's I index and GIS geostatistic interpolation methods,spatial autocorrelation and spatial distribution of organic carbon density( SOCD) in forest soils of Zhejiang Province were studied and effects of factors affecting SOCD were analyzed using the linear-regression equation. Results show that SOCD in the 0 ～ 30 cm layer of the forest soils of Zhejiang Province was 71. 2 t hm- 2,on average,lower than the country's. The overall Moran's I of the SOCD in Zhejiang Province was 0. 176,demonstrating significant spatial autocorrelation. SOCD in the forest soils of Zhejiang Province displayed in distribution a gradient declining from southwest to northeast and three parallel belts.Significantly positive relationships were found of SOCD with dominant tree species,slope position,slope aspect,age group,altitude,shrub coverage,shrubs average height and average age,and a significantly negative relationship was found with herb coverage. SOCD in the 0 ～ 30 cm soil layer was not much affected by herb average height. All these influencing factors explained 14. 9% of the variation of SOCD.
