工程堆积体陡坡土壤侵蚀动力过程试验研究

, 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 ...

Impact of slope biological regulated measures on soil water infiltration

, 2010
为了研究不同生物调控措施的植被覆盖度、降雨强度和坡度以及各因素间交互作用对土壤水分入渗的影响,本文通过室外人工模拟降雨试验,对不同生物调控措施坡面的土壤水分入渗规律进行了探索。结果表明:1)有生物调控措施坡面的土壤稳定入渗率较裸坡偏大,且差异极显著,但生物调控措施坡面之间的差异并不明显。2)降雨强度、坡度与土壤稳定入渗率间不是线性单值函数,均存在使土壤稳定入渗率最大的临界雨强与临界坡度。稳定入渗率随植被覆盖度增加的速率是非恒定的,存在着增速变化的临界植被覆盖度。临界植被覆盖度前,稳定入渗率的增加速率很快,
