摘  要：
运用地统计学分析方法,研究了2010年鼎湖山季风常绿阔叶林中土壤有机碳和全氮含量的空间分布特征.结果表明:在鼎湖山季风常绿阔叶林,土壤有机碳和全氮含量存在着较显著的空间自相关性,其空间异质性分别占总空间异质性的93.6%和53.7%,且土壤有机碳与土壤全氮空间分布特征的异质性一致.林地土壤碳、氮存在传统统计学上的线性相关,同时也具有景观层次上的空间自相关性.指数模型拟合结果表明,在17.4 m小尺度范围内,土壤有机碳存在空间自相关性.

摘  要：
Geostatistical techniques were used to quantify the spatial heterogeneity of soil organic carbon and total nitrogen of one monsoon evergreen broadleaf forest area in Dinghushan,Guangdong,China. The results demonstrated that a significant spatial autocorrelation existed between soil organic carbon and total nitrogen contents in the Dinghushan monsoon evergreen broadleaf forest, such that 93. 6% and 53. 7% of their total spatial heterogeneity originated from their spatial autocorrelation. This observation agreed with a traditional statistics analysis showing a significant linear correlation between soil organic carbon and total nitrogen,and also their spatial autocorrelation existed at a landscape level. The best fit from an exponential model showed that soil organic carbon had high degree of spatial heterogeneity at a scale of 17. 4 m.
