【摘要】 本文对塔克拉玛干沙漠和古尔班通古特沙漠的风沙土土壤理化特性进行了对比分析，结果表明：两大沙漠风沙土土壤肥力无明显差异，土壤有机质很低；塔克拉玛干沙漠风沙土在全盐、ＣａＣＯ３含量上高于古尔班通古特沙漠；塔克拉玛干沙漠风沙土分选好，颗粒组成以细沙为主，而古尔班通古特沙漠风沙土分选较差；两大沙漠风沙土在２４种化学元素含量上多数存在明显差异。更多还原

【Abstract】 The paper compares the physical-chemical characteristics of aeolian soils between the Taklamakan Desert and the Gurbantonggute Desert. The results are as follows:1. Soil fertility of aeolian soils has no obvious difference in the Taklamakan Desert and the Gurbantonggute Desert.2. Contents of total salt and CaCO3 of aeolian soils in the Taklamakan Desert are higher than those in the Gurbantongute Desert.3. Grain size of aeolian soils is .mainly fine sand and has a well sorted characteristic in the Taklamakan Desert,whereas grain size of aeolian soils is mixed and has a poor sorted feature in the Gurbantonggute Desert.4. Many chemical elements of aeolian soils have obvious difference between the Taklamakan Desert and the Gurbantonggute Desert.更多还原
