通过室内土柱试验, 利用经典统计分析、地统计学分析和分形分析, 分别对比研究了黏粒含量对土壤含水率空 间变异规律的影响, 结果表明: 土壤中由于一定量黏粒的存在会影响土壤含水率空间变异的垂向距离, 从而改变土 壤含水率的空间结构, 也会影响土壤含水率垂向分布的均匀程度。

Based on the laborat ory so il column ex per iments, the effects of clay content o n the spatial va riation o f soil moistur e co ntent w ere investig ated using the classical statist ical analy sis, geo st atistical analy sis, and fr acta l analysis. The r esults indicated that the o ccurr ence of cla y in the so il can pr olong the vert ical distance of spatial var iation o f so il mo isture content and then change the spat ial str ucture o f so il moisture content, and can also affect the homo geneous deg ree of vert ical distr ibution of so il moisture content.
