摘　　要：在吕梁山南段对不同林地的土壤持水力进行了测定:结果表明:不同林地土壤含水率由小到大的排序为:天然次生林地>油松人工林地>灌木林地>对照;林地土壤具有较强的持水能力,其中天然次生林地土壤持水力最大,1 m深土壤持水力为113.0 t/hm2,分别为灌木林和农地的2.3倍和5.45倍。The soil water holding capacity of different forestlands was investigated in the south of Lvliang Mountain. The result showed that the order of soil water holding capacity of different forestland was ： naturally regenerated forest）artificial pine forest）shrub forest）contrast. The soil capacity of naturally regenerated forest is the first, with 113.0 tons per hectare at 1 meter deep, is 2.3 and 5.45 times as much as that of shrub forest and farmland, respectively.
