, 2014 随着我国基础设施建设项目投资力度的不断加大，各类生产建设项目增加迅猛，全 国到处是新开的建设工地，建设中大量的植被遭破坏，地表和地下土体被扰动、剥离、 运移和松散堆置，造成了严重的人为水土流失。施工过程形成的大量弃土弃渣体，亦即 工程堆积体，因无任何防护措施，成为水土流失最为严重的地方，同时也成为人为新增 水土流失最主要的泥沙策源地，造成了局部生态环境的进一步恶化。全国各类生产建设 项目的水土保持方案编制中，关于水土流失测算，仍采用类比法等，缺乏实验依据与模 型的理论支撑，精度不高 ...

Shuitu Baochi Xuebao[目的] 为研究降雨、汇流和坡度对浅沟侵蚀的影响,实施精确的水土保持措施。[方法] 通过室内模拟降雨和汇流试验,设计2个降雨强度(50,100 mm/h)和2个坡度(3°,7°),并在4种降雨强度和坡度组合下设置5个依次增加的汇流强度(15,30,45,60,75 L/min),分析降雨、汇流和坡度及其交互作用对浅沟坡面侵蚀的影响,明确浅沟侵蚀对坡面侵蚀的贡献。[结果] (1)坡度和汇流强度对浅沟坡面侵蚀的影响均大于降雨强度。当降雨强度由50 mm/h增加到100 mm/h时,3°和7 ...

选择太湖上游为研究对象,采集了1-400 km2不同尺度小流域产出径流TN、TP浓度实测数据,结合前期开展的地表坡面流人工暴雨实验监测结果,开展不同尺度流域水质监测对水体面源污染产出浓度估算影响的比较研究,探讨流域尺度之间入渗、汇流以及伴随的流域生态系统营养盐调节机制的差异．结果表明,流域监测尺度对土地利用面源污染产出浓度估算有较大影响．地表坡面流由于未经过流域汇流过程伴随的下渗滤过与吸附等过程,产出径流TN、TP浓度一般高于小流域．小流域林地生态系统具有较强的入渗机制、接近自然的生态沟谷汇流网络 ...
