Shuitu Baochi Xuebao, 2011 以三峡库区紫色土旱坡地为研究对象,采用野外径流小区观测方法,研究了三峡库区旱坡地不同坡度下土壤磷素的流失特征.结果表明,地表径流量和侵蚀泥沙量都随着坡度的增大而增大,且径流量和泥沙量是先增大后减小,最后趋于稳定.地表径流和侵蚀泥沙中磷素的流失量均呈l7°＞9°＞4°的趋势.地表径流中,颗粒态总磷流失量是水溶态总磷流失量的1.50～1.51倍.全磷主要吸附在泥沙中流失,磷素随泥沙的流失量占总流失量的85.0%～94.1%.研究结果为三峡库区旱坡地磷素的管理提供理论依据.

Shuitu Baochi Xuebao, 2002 采用人工模拟降雨装置 ,对红壤坡地养分流失特征进行了试验研究 ,结果表明 :在雨强较大情况下 ,土壤养分以泥沙形式随径流迁移 ;当雨强较小时 ,随径流迁移的可溶态养分流失量占流失泥沙养分量的比例较高 ,土壤养分流失氮、磷、钾分别达到 5 3.12 % ,2 3.1% ,2 1.5 % ;不同形态的养分在流失泥沙中均有养分富集现象 ,但富集率各不相同 ;土壤养分流失量与雨强及泥沙流失量呈正相关关系。
