摘  要：
用土钻法连续5年对荒坡地不同坡向、坡位的土壤水分进行了定位测定,表明不同坡向土壤水分差异显著,南坡和北坡相比,0～2m土层北坡含水量高,但1～2m土层南坡比北坡土壤含水量高。荒坡地耗水深度南坡2.3m,北坡1.3m。坡地蒸散平均305～335mm,其中90%来自大气降水。

摘  要：
This paper has studied the soil moisture content of the slope land(for the different direction slopes,the different site of the slope).The data has been gotten by the soil auger method at the same pinpoint for 5 years(1985—1989). The soil moisture content of the different slopes are obvious difference.The soil moisture content of northern slope is more than the southern slope's in the 0—20cm soil layer.but the northern slope's is less than the southern slo- pe's in the 100—200cm layer.The main depth of the consumed soil water is 2.3m at the southern slope and about 1.7m at the northern slope.The mean evaporation in the slope land are about 305—335mm,the ninety percent of the sum evaporation comes from rainfall.
