摘　　要：对陕西关中西部的苹果人工经济林和槐树人工生态林林地土壤剖面的结构、土壤的粒度组成进行了系统研究。结果表明:(1)人工生态林林地所设的YSL土壤剖面其土壤的碳酸钙淋溶作用较人工经济林林地所设的YSP土壤剖面强;(2)YSP与YSL土壤剖面不同发生层,其土壤粘粒与砂的含量变化差异较粉砂大;(3)YSP土壤剖面的土壤粘粒较YSL土壤剖面的淋失深度浅,但淋溶量大;(4)YSP土壤剖面表层土壤的粘粒含量较YSL土壤剖面高,表明精细的人为管理方式对其林地表层土壤的粘化有显著影响。The structure of soil profile structure and grain size of artificial ecological forest were studied. The results were as the follows： 1） CaCO3 eluviation in YSL soil profile from better than YSP soil profile from economic forest. 2） The content of clays and sands changed and economic forest ecological forest was more significant than sih in different genetic horizons of the two research soil profiles. 3） The depth of clays eluviation in YSP soil profile is shallower than in YSL soil profile, but leaching amount bigger. 4） The surface clay content of YSP soil profile higher than YSL soil profile, which indicated that artificial elaborate management affected the clayification significantly.
