, 2013 生产建设区水土流失是生产建设背景下集各类环境因子控制、人为因素影响及下 垫面条件为一体的综合环境影响体现，改变了原有地表物质组成、结构、形态及水沙 发生、发展规律。作为生产建设项目区人为生产建设活动产生的废弃物堆置而成的特 殊地貌单元，工程堆积体是生产建设区新增水土流失的重要来源，进一步探讨不同扰 动方式下工程堆积体坡面的土壤侵蚀过程、径流水动力学特性及侵蚀产沙的动力过程 对于深化对生产建设区不同地貌单元土壤侵蚀特征的认识和理解具有重要的实际意 义，本文以神府高速公路沿线典型弃土场为例 ...

, 1997 采用稀土元素（REE）示踪法对坡面侵蚀垂直分布特征动态变化过程进行了初步研究。结果表明．坡面侵蚀垂直分布特征在次降雨过程呈动态变化趋势．尽管在产流过程中相对侵蚀量的变化趋势基本相似．但比值差异很大，这主要取决于坡面径流的强度。此外、次降雨侵蚀产沙的垂直分布特征与侵蚀过程中产沙的分布特征差异亦很大 ...

Effect of Different Soil and Water Conservation Measures to Rainfall Redistribution on Slope
, 1996 黄土高原丘陵沟壑区地形支离破碎，坡面陡峭．天然降雨在坡面发生再分配，加剧水土流失。在坡面上实施不同的水土保持措施后，结果表明，隔坡梯田和水平梯田拦蓄降雨，就地入渗，消除了降雨再分配发生的条件。水平阶种植草灌带，迟滞缓解降水在坡面的再分配过程，连续切断坡面径流流线，抑制径流泥沙发生。坡面水土保持乔木林，蒸发蒸腾旺盛，使得坡面土壤水分过度消耗亏缺，生长迟缓 ...
