| 摘 要： | 本文对黄河三角洲的砂质壤土及砂质粘壤土的部分物理特性,在二维空间平面上的空间变异结构做了初步探讨。结果表明,近代黄河三角洲土壤物理特性的空间分布不是完全随机的,而是在一定的空间范围内具有相关性,当观测点间的距离超过某一范围,相关性则消失,此时才具备随机统计理论的条件。

| Abstract: | The two-dimensional space variability of some physical properties of sandy loam and sandy clay loam in the Yellow River Delta was investigated. The results showed that the spatial distribution of physical properties of soils in the Delta was not completely random, but had some correlation in a given spatial range. When the distance between sampling points was beyond this range, the correlation would disappear. |

| Keywords: | autocorrelation semivariance structure of spatialvariability spatial variability correlation range |
