摘　　要：通过对西安污灌区菜地与耕地土壤进行研究,试图探讨土地利用方式对土壤理化性质的影响。结果表明:土壤TOC、pH值和CaCO3表现为农田>菜地;<10μm颗粒含量农田高于菜地,>10μm颗粒含量农田低于菜地;农田土壤表层TOC和CaCO3值变异性大,菜地下层土壤TOC和CaCO3值变异性较大,而两剖面中pH值变异不大。The effect of land use on physical and chemical properties of vegetable soil and cultivated soil were studied in the northern suburb of Xi＇an sewage irrigation in this paper. The results showed： the content of soil TOC, pH value and CaCO3 of farm- land were more than that of vegetable soil; the content of soil granule smaller than 10 μm in farmland was more than that in vegetable soil, while soil granule bigger than 10 μm in farmland was less. The variability of TOC and CaCO3 in upper land of farmland was big, while the variability of TOC and CaCO3 in subsoil of vegetable soil was big. And pH value showed no remarkable difference in different land use.
