The paper introduces the research on comprehensive control technology of soil and water loss and nitrogen and phosphorus loss in stormed crack and excessive eroded soil in Dianchi lake basin.
介绍了滇池流域冲沟和强侵蚀区水土和氮磷流失控制研究的内容、方法及取得的效果等。
4) loss of nitrogen and phosphorus
氮磷流失
1.
At Shixia experimental plots, the loss of nitrogen and phosphorus from sl.
免耕种植、梯田种植、鱼鳞坑造林等水土保持措施有效的减弱径流氮磷的流失；在其它条件相同的情况下，植被覆盖可明显减少径流量和泥沙量，从而有效地控制氮磷流失；坡度大的小区氮磷流失量、泥沙量高于坡度小的小区；土壤含水率对氮磷的流失也有明显的影响；前期土壤含水率越高，污染物的流失量也越大。
