摘要

采用人工降雨和自然降雨的方法对紫色土坡地磷素迁移进行比较研究。研究结果表明：紫色土坡地产生地表径流和壤中流两种径流模式，壤中流其径流动态过程受降雨强度和表层作物覆盖度的影响；持续性变化的大雨强更容易引起土壤磷非点源输出，导致水体富营养化；在中到暴雨条件下，壤中流累积迁移流量低于地表径流，差幅决定于土壤表层界面（植被覆盖）特征，地表径流中的磷迁移量是壤中流迁移的3～4倍。

Abstract

Phosphorus transport form slope cropland of purple soil at natural rainfall and simulated rainfall events were compared in this study.The results showed that

there were two process: overflow and subface flow.Runoff dynamic course were influenced by different rainfall intensity and crop coverage.The variation of rainfall intensity led to phosphorus moving through subface flow and resulted in eutrophication of local water.The flow charge of overland was bigger than the subsurface flow in both events

then exported different phosphorus loads.
