摘要
在昆阳磷矿矿区采取了不同的植被恢复措施,并对不同恢复时期的土壤侵蚀状况进行了观测,结果表明:土壤侵蚀现象随植被恢复年限的增加而降低;相同植被类型的样地内土壤侵蚀随降雨强度的增加而加剧;降雨和土壤侵蚀呈现出3各阶段的规律;植树造林有良好的保土保水作用。
In Kunyang Phosphate mining area, we carried out different vegetation restoration measures and observed soil erosion of different restoration periods. Here we drew the conclusion： soil erosion phenomenon decreased with vegetation restoration years increased; soil erosion in the same vegetation types intensified with the increasing rainfall intensity; rainfall and soil erosion showed the rule of three phases; afforestation had good soil water retention.
