冻融作用对土壤含水率、pH值、电导率的影响

Effects of Freeze Thawing on the Moisture,pH Value and Conductivity of the Soil

我国对土壤冻融作用研究主要集中在自然环境条件下冻土环境变化。文章对齐齐哈尔市南郊污水处理厂附近的氧化塘中的冻融土壤进行研究,论述了冻融作用对土壤三参数的影响。研究表明,季节性冻融作用对土壤的含水率、pH值、电导率都有影响,尤其是对含水率的影响较大。

The study on the soil freeze thawing in China centers on environmental changes of permafrost under the natural conditions.The paper studies the freeze thawing soil in the oxidation pond near the sewage treatment plant of the southern suburbs of Qiqihar city and explains the effects of freeze thawing on the three parameters of the soil.The result shows that seasonal freeze thawing may affect the moisture,pH value and conductivity of the soil,especially the moisture.
