摘要：采用地统计学的方法,对海南岛尖峰岭热带山地雨林原始林土壤物理性质小尺度空间异质性进行了研究,结果表明:(1)土壤各物理性质空间异质性明显,其半方差函数可以用指数模型、高斯模型和球状模型拟合,变程变化范围为10.810 48.650 m,块金值与基台值比值范围为10.2%87.8%,表明各物理性质有不同程度的空间自相关性;土壤孔隙度和持水特性有较大的块金值,说明存在小尺度(<10 m)的空间异质性;(2)普通克里格插值及绘制物理性质空间分布轮廓图表明,土壤各物理性质在空间分布上具有斑块性,各物理性质在不同土壤深度的空间分布有一定的一致性,地形是影响土壤物理性质空间分布格局的一个主要原因。
The fine-scale（1 hm2） spatial heterogeneity of the soil physical properties in a primary tropical montane rainforest of Jianfengling,Hainan Island was investigated with geostatistics.The results demonstrated that：（1）the exponential,Gaussian and spherical models separately well fitted the soil data at different layers.The ranges of all the soil physical properties and the ratios of nugget versus sill at the different layers ranged from 10.810 to 48.650 m and 10.2%-87.8%,respectively.The soil porosity and water retention had a large nugget effect in a smaller scale（10 m）,indicating a strong spatial autocorrelation;（2）Both the ordinary Krige analysis and contour maps showed that there were several remarkable patches of all soil physical properties in the sample area.The spatial patterns of all the soil physical property at different sample depths were concordance with each other to a certain extent;（3）It was identified that the topography was a principal factor resulting the spatial patterns of all the soil physical properties of interests.In summary,it is concluded that all the soil physical properties were strongly spatial autocorrelated in the 1 hm2 primary tropical montane rainforest of Jianfengling,Hainan Island.
