| 摘 要： | 在华北山地典型天然次生阔叶混交林中选择研究样地,应用地统计学理论,定量分析林分土壤表层含水量空间异质性特征。研究结果表明:以白桦和山杨为优势树种的阔叶混交林,不同空间样点间土壤表层含水量差异不大。土壤表层含水量在较小尺度范围(13.10 m)空间异质性明显,空间自相关因素所占比重较大(71.9%)。空间格局强。

| Abstract: | By geostatistic, the heterogeneous spatial distribution of topsoil moisture in typical naturally-regenerated montane broad-leaved mixed forests of Northern China were analyzed quantitatively. The results showed that in Betula platyphylla-Populus davidiana dominated broad-leaved forests, the topsoil moisture did not differ greatly among different quadrats. The heterogeneous spatial distribution of topsoil moisture was obvious in a small range (13.10 m), the spatial auto-correlated factors accounted for a large proportion (71.9%). A great spatial pattern was observed. |
