摘要
开发建设项目的水土流失不同于自然环境中的水土流失,而是典型的人为水土流失。而线形工程由于其人为施工活动呈线形的破坏,造成水土流失的特殊性,本文以国家高速公路网大庆至广州公路双辽(蒙古界)至通辽段为例探讨了线形工程水土流失预测。划分了水土流失预测时段和区域,阐述了水土流失预测的内容和方法,预测了水土流失的背景值和水土流失强度以及水土流失量,为线形工程的水土流失预测奠定基础。
Loss of soil and water for Construction projects is differ from that in entironment and belongs to man-made soil and water loss. Linear engineering projects have particularity because man-made construction activities show linearity. The part of expressway from Daqing to Guangzhou in the national expressway net, that is from Shuangliao to Tongliao was taken as the research area to discuss soil and water loss forecast for linear engineering projects. Partition periods of time and areas about soil and water loss forecast, expatiate content and means, forecast background value、intensity and quantity, settle foundation for prevention and control of soil and water loss.
