冻融作用对土壤中总磷含量的影响

Effects of Freezing and Thawing on the Content of Total Phosphor in 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。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中总磷含量的影响。研究表明,季节性冻融作用对土壤总磷含量有较大影响。

The effect of freezing and thrawing of the soil was focused on the natural environment under the conditions of permafrost environmental change in our country. The research of freezing and thrawing soil in the oxidationpond near the southern suburbs of Qiqihar city sewage treatment plant was conducted. The effects of freezing and thawing on the content of total phoshor in soil were hiscussed. The studies showed that the content of total phosphor insoil was influential by seasonal freezing and thrawing.
