摘　　要：对林芝地区退耕地不同植被类型下土壤理化性质进行分析,结果表明:不同植被类型退耕地的土壤理化性质存在差异。林芝县布久乡杰麦村退耕还林核桃地内土壤结构疏松,土壤田间持水量大,土壤物理性质最好,其次为同村的退耕还林柳林地、米林县羌纳村退耕还林核桃地,后山退耕还草地最差。从化学性质看,米林县羌纳村退耕还林核桃地的有机质、N、P、K等养分含量最高,说明米林县羌纳村退耕还林核桃地的化学性质最好。This paper analyzed the soil physical and chemical properties of abandoned lands under different vege tation types in Nylingchi.The results showed that the soil physical and chemical properties of abandoned lands under different vegetation types were different.The soil physical properties were the best with loose soil struc ture and large soil field capacity in walnut ground returned from grain plots at Jiemai village,Bujiu village,Nying chi County.It followed by the willows ground,walnut ground at Qiangna village,Milin County.The meadow re turned from grain plots at Houshan was the worst.The nutrient contents of organic matter,N,P,K and others were the highest in walnut ground returned from grain plots at Qiangna village,Milin County,which mean the chemical properties in the walnut ground returned from grain plots at Qiangna village,Milin County,were the best.
