细颗粒泥沙絮凝-分散在水土保持中的应用

简要介绍了细颗粒泥沙絮凝 -分散对土壤渗透性、土壤可蚀性以及污染物迁移的影响 ,以期有效防治水土流失和由此带来的非点源污染。

Water resources shortage is a very important factor to obstacle sustainable development of agriculture in the arid and semiarid regions. Many researchers are making their all efforts to search ways to improve soil penetrability. One of the measures is to spread amendments on soil to flocculate fine sediment, increase soil penetrability, and decrease soil and water loss. In this paper, the effects of fine sediment flocculation and deflocculation on soil penetrability, soil erodibility and contaminants transp...
