| 摘 要： | 通过对山西省吉县蔡家川小流域坡面25个样点土壤水分的测定（烘干法），采用地统计学方法研究了晋西黄土区坡面土壤水分时空变异规律。研究结果表明，理论变异函数模型很好地反映了晋西黄土区坡面土壤水分的空间结构特性。不同坡向的土壤水分具有强烈和中等的空间自相关，这意味着土壤水分在坡面尺度上具有明显的空间自相关。这一点也可以从分维数的大小得到验证。通过运用地统计学方法对土壤水分的分布进行分析，为研究晋西黄土区土壤水分时空分布规律提出了新的研究思路。

| Abstract: | Temporal and spatial distribution of soil moisture in the loess area of West Shanxi Province is studied by using the geological statistics method.Results show that the variation function model can well describe the spatial features of soil moisture.Soil moisture on different slopes has strong and moderate spatial autocorrelation,which indicates that it has the significant spatial autocorrelation on slope scale.The result can be validated by the fractal dimension.The distribution of soil moisture is analyzed... |
