中文摘要:
      通过样地调查和土壤理化性质分析对新疆阿拉尔垦区荒漠植被下的土壤特性进行了研究,结果表明:研究区土壤颗粒组成以砂粒为主,有机质在表层积聚现象明显,土壤氮、磷含量偏低,土壤钾素含量较高。供试土壤的pH呈碱性反应。依照《中国土壤系统分类检索(第三版)》,研究区的土壤类型在系统分类中可归属为3个土纲、3个亚纲3、个土类和4个亚类,其中剖面T-01属于暗沃简育湿润雏形土,剖面T-02属于石灰干旱正常新成土,剖面T-03属于斑纹简育湿润雏形土,剖面T-04属于暗瘠简育正常潜育土。
英文摘要:
      Through soil and plant survey in the sampling site and determination for soil physical and chemical properties,soil properties under the desert vegetation in Aral irrigated area were studied.The result showed that sand content was the highest in the particle composition,accumulation of organic matter in topsoil was very clear,soil nitrogen and phosphorus content was relatively low,soil potassium content was relatively high,and soil pH showed alkaline reaction. According to the Chinese Soil Taxonomy(3rd edition),the soils tested belonged to 3 soil classes,3 subclasses,3 great soil groups and 4 subgroups.That is to say,T-01 belonged to Mollic Hapli-Udic Cambosols,T-02 belonged to Calcaric Aridi-Orthic Primosols,T-03 belonged to Mottlic Hapli-Udic Cambosols,and T-04 belonged to Umbric Hapli-Orthic Gleyosols.
