开发建设项目水土流失是一种典型的人为加速侵蚀现象,不论从外营力,还是从侵蚀速度、强度及所造成的危害来看,它都与原地貌状况下的自然水土流失存在着显著差别。这就要求对开发建设项目水土流失机理、特征、流失量的变化实施全过程的监控。随着监测工作的深入开展,一些工作中新的、实际问题也在逐渐显现。通过对辽宁省水土保持监测工作中存在的问题进行分析探讨,提出了解决这些问题的思路和方法。
Soil and water loss in development and construction projects is a typical phenomenon of man-made accelerated erosion. It shows significant differences from natural soil erosion under the condition of the original landform, both from the external force and from the erosion rate, intensity and the harm caused . This requires the monitoring and control of the entire process of changes in soil erosion mechanism, characteristics, and loss of development and construction projects. With the in-depth monitoring work, new and practical problems in some work are gradually emerging. Through the analysis and discussion on the problems existing in the monitoring work of soil and water conservation in Liaoning Province, the ideas and methods for solving these problems are put forward.
