摘　　要：对大伙房水库库区附近4种河岸林土壤进行取样,采用相关性分析,研究了4种不同类型河岸林中土壤物理和化学性质。结果表明:4种不同类型的河岸带森林土壤中,6种理化性质均存在显著性差异。改造后油松林的土壤中p H、含水量、总碳和总氮质量分数均为最高,而土壤密度和总磷质量分数最低。We studied the soil physical and chemical properties in four types of riparian forests around Dahuofang Reservoir.There were differences in six properties among four types.Pinus tabulaeformis（after conservation） had much higher value in p H,water content,C and N.However,it had a relative lower value on soil density and P.Therefore,P.tabulaeformis forest management could improve the capabilities of carbon sequestration,water retention and nutrient reservation.
