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。
Soil and water loss of development and construction projects is different from soil and water loss in the natural environment, but a typical man-made soil and water loss. However, due to the linear damage of linear engineering caused by man-made construction activities, the particularity of soil erosion is caused. This paper discusses the prediction of soil and water loss of linear project from the national expressway from Daqing to the Guangzhou highway Shuangliao (Mongolia) to Tongliao section. The time and area of soil erosion prediction were divided. The content and methods of soil erosion prediction were expounded. The background value of soil erosion, soil erosion intensity and soil erosion amount were predicted, which laid the foundation for soil erosion prediction of linear engineering.
