土蚀

水土流失（土蚀）是自然水污染的一个例子，如果土壤阻塞水流会造成难题，导致洪水泛滥。

Soil erosion is one example of natural water pollution and can cause problems if the soil blocks the flow of water and leads to flooding .

不同植物类型下紫色土抗蚀性研究

Studies on Anti & Erodibility of Purple Soil under Different Vegetations

采用最大30分钟雨强大于25～30mm／hr降雨的侵蚀产沙资料，计算的土壤可蚀性值比较稳定且接近这土类可蚀性的多年平均值。

But the field runoff plot data of which the maximum 30-minute rainfall intensity is larger than 25-30mm / hr are used to calculate the soil erodibility , the values appear relatively stable and approaches to annually average erodibility value .
