孟西灌区位于洛阳市孟津县西部的黄河南岸,属秦岭余脉熊耳山与北邙山交界地带,土壤侵蚀模数在每年5000～7000t/km~2之间,是水土流失较为严重的地区,同时又是省、市划定的水土流失重点治理区和重点预防保护区,该工程的水土流失防治工作与其他水利工程有很多共性问题,本文就以孟西灌区为例,对搞好当前水利工程建设的水土流失防治进行探讨。
Mengxi Irrigation District is located on the south bank of the Yellow River in the western part of Mengjin County, Luoyang City. It belongs to the junction of Xiong’ershan and Beijiao Mountain of the Yumaili Mountains in Qinling Mountains. The modulus of soil erosion is between 5000 and 7000t / km ~ 2 per year, which is a serious area where soil erosion is serious. At the same time, it is also the key area for water and soil loss and the key area for prevention and protection designated by the province and city. The prevention and control of soil and water loss in this project has many common problems with other water conservancy projects. This paper takes Mengxi Irrigation District as an example, Prevention and Control of Soil and Water Loss in Construction.
