黄土丘陵沟壑区管道建设工程土壤侵蚀预测及防治措施

管道建设过程中植被剔除、地表开挖、土壤堆积松散,加重了当地的土壤侵蚀。结合管道建设特点和陕北黄土丘陵沟壑区环境特征,以刘坪—姚店输油管道建设为例,对黄土丘陵区管道建设工程的土壤侵蚀量进行了预测,包括弃土(渣)及扰动原生地貌可能产生的土壤侵蚀量。为减少和防止土壤侵蚀,根据管道建设的特征和当地情况提出了相应的工程、植物等综合治理措施。

Forecast and Control of Soil Erosion in Pipeline Engineering Construction and Laying in Hilly and Gully Area of Loess Plateau

In the all processing of pipe constructing and laying, vegetation-eliminated and earth surface avulsed and soil piled incompact resulted in soil erosion more seriously. According to the character of pipeline constructing and laying and the local environment of the loess hilly and gully area in Shaanxi Province, the Liuping to Yaodian oil transportation pipe is taken as an example to forecast the amount of soil loss which includes discarding soil and dregs, destroying original landforms. To induce and avoid the loss, some integret-ed measures, such as ecological engineering and other kinds of measures, are put forward accordingly.
