横泉地区黄土含水率变化特点

The Changing Features of Moisture Content of Loess in Hengquan Area

通过对横泉地区黄土的颗粒分析、含水率的测定及黄土溶液电导率的测定,系统地研究了黄土层含水率的变化特点,初步认识到在同一黄土剖面上,土壤质地是决定含水率大小的重要因素,在富含气体的黄土层中,黄土含水率的变化与粘土颗粒含量具有明显的正相关关系,含水率与电导率之间从上到下呈波动关系。

Through the particle-size analysis of loess, measurement of moistu re content and determination of loess solution conductivity, this paper systematic ally studies on the changing features of the moisture content of loess stratum, and recognizes preliminarily that on the same loess cross section the soil quali ty is an important factor determining the volume of the moisture content, and in gas rich loess stratum, the variation of loess moisture content possesses obvio us positive correlation with clay particle content, and between the moisture con tent and the conductivity there is a fluctuation from top to bottom.
