| 摘 要： | 拟建的新街-恩格阿娄铁路穿过水土流失强度大的鄂尔多斯剥蚀丘陵区和毛乌素沙漠区,铁路建设的施工过程会增大沿线的水土流失量。本研究采用模式预测法对施工期内不同的施工单元和地类的水土流失量进行了估算。结果表明,工程建设区域内原地貌背景水土流失量为3.79×10^4t,在施工期间如果不采取任何防护措施,工程建设可能造成的水土流失量为7.47×10^4t,可能造成的新增水土流失量为3.69×10^4t,主体工程新增的水土流失量最大,达到2.4×10^4t,占可能新增的水土流失总量的65%左右,取土场次之,占28%左右,施工场地及营地新增的水土流失量最小,不到新增水土流失总量的1%。在水土流失防治上,重点防治区段是主体工程区、取土场和临时堆土区,本文对不同的施工单元提出了包括工程措施、植物措施和临时防护措施在内的水土流失防治对策。
