摘　　要：黑土水土流失日益严重,解决水土流失问题已迫在眉睫.文中从土壤持水能力出发对裸地(BL)、草地(GL)、农田(CL)和森林(TL)内不同深度(0～60 cm)的进行了分析并作出比较.结果表明:草地、农田和森林下的土壤,从层次上看都具有较裸地较小的土壤容重,较高的孔隙度和持水量,并且草地(GL)的土壤持水能力要优于其他利用方式.Black Soil erosion was became increasingly serious, which should immediately solution to the problem of soil erosion. This article from the soil water--holding capacity ,which according to analyze and compare Bald Land,Grass Land, Crop Land and forest land＇s soil pore and water preserving capability in different depth, from 0 centimeter to 60 centimeters. The results indicated that the soil under Grass Land, Crop Land, forest land all have the lower bulk density of soil, higher soil porosity and water--holding capability of soil than Bald Land. And grass land（GL）of water--holding capability of soil is superior to other patterns.
