Abstract:
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.
