公路建设中水土流失预测与防治的研究

Prediction of Water Loss and Soil Erosion and Prevention-Treatment of Them in Highway Building

分析了高等级公路建设中水土流失的成因,利用水土流失预测数学模型对可能造成的水土流失量进行了估算,根据工程水土流失的特点、危害程度和防治目标,介绍了分区、分期的防治措施。可为高等级公路建设中的水土保持、生态环境建设及其周边地区环境资源的开发利用提供借鉴和参考。

The paper analyzes reasons for water loss and soil erosion in high -type highway building, makes estimation of amount of water loss soil erosion probably brought about with math model, and introduces measures for prevention - treatment by stages and by districts in response to features of water loss and soil erosion, their hamLful extent as well as objective for prevention -treatment of them,which might provide use and reference for water and soil conservation, ecology environment building along with surroundings＂ natural resources tapping and utilization.
