摘要

半干旱黄土区不同土地利用的土壤水分效应是农业生产、植被恢复和土地合理利用的重要依据。通过对孙家岔流域不同土地利用格局实测土壤水分资料分析

结果表明

梯田区阴坡的土壤含水率高于阳坡;梁峁顶区封闭荒地不同累积深度的土壤含水率均高于农地;缓坡区(<15°)农地土壤平均含水率高于荒地;灌木林地表层(0—80cm)土壤含水率高于荒地

而较深层(80—180cm)低于荒坡;松树林地平均土壤含水率高于杏树林地。说明在半干旱黄土区

梯田的保水效益最好;杏树林相对于松树林耗水量更大

不适宜在无灌溉条件的半干旱黄土区大面积种植;柠条灌木林改善地表土壤水分状况的效应明显

并且能充分利用较深层的土壤水分;缓坡区种植农作物比荒地更有助于土壤水分的改善。

Abstract

In the semiarid loess hilly region

the condition of soil moisture under different land use patterns is of importance to agricultural production

vegetation restoration and rational land use.Results from the analysis of soil moisture data under different land use patterns in Sunjiacha watershed show that soil water content on the north-facing slope was higher than the south-facing slope.Soil moisture contents at different depths in the enclosed land of the hill top zone were higher than farmland.The average moisture content in farmland of the gentle slope zone(<15°)was higher than the abandoned field.Soil moisture content of surface layer(0-80cm)in shrub land was higher than the abandoned field

but of the deeper layer(80-180cm)

was lower than barren slope.The average soil water content in pine woodland was higher than apricot forest.These indicated that in the semiarid loess hilly region

terrace's water conservation benefit is the best;apricot forest has higher water consumption than pine woodland and thus

is not suitable for the large scale planting without irrigation conditions;Caragana microphylla can significantly improve surface soil water status and sufficiently use the deeper soil moisture;and in the gentle slope zone

planting crops can enhance soil moisture better than the abandonment.
