| 摘 要： | 本研究在毕节关门山流域,选取乔木林地、灌木林地、荒地、果园及玉米地五种不同土地利用类型,研究了不同土地利用类型对土壤含水量和容重的影响,结果表明：1）在乔木林地和灌木林地表层土壤含水量随坡长增加变化不大,且乔木林地高于灌木林地;2）乔木林地和灌木林地坡脚土壤含水量高于坡中,坡中高于坡顶;3）五种土地利用条件下0-80cm深度内土壤含水量均随深度增加而递增;4）表土容重的变化次序为：乔木林地〉灌木林地〉果园地〉荒地〉玉米地。

| Abstract: | The paper studied the effect of different types of land use on soil moisture and bulk density, via choosing arbor land, shrub land, abandoned land, orchard and corn field at Guanmenshan valley in Bijie. Results showed that： 1） soil moisture contents of arbor land and shrub land changed slightly with increasing slope length in the surface soil, but soil moisture contents of arbor land were higher than shrub land. 2） soil moisture contents of slope toe were higher than slope middle in arbor land and shrub land, and slope middle higher than slope top.3） soil moisture contents increased with depth in 0-80 cm soil depth under five land-use types. 4）The densities of super soil layer were arranged in the following sequence： arbor landshrub landorchard abandoned landcornfield. |
