Abstract
The rocky mountainous region in Northern China serves as a critical energy transmission corridor,characterized by complex topography,fragile ecosystems,and concentrated precipitation.This paper analyzes the characteristics,spatiotemporal distribution patterns,and driving factors of soil and water loss during various phases of power transmission and transformation project construction in this region.It also summarizes the application effectiveness of existing engineering,vegetative,and temporary measures,as well as their combination models.The study demonstrates that targeted measures can effectively reduce the degree of soil erosion.However,challenges persist,including systemic deficiencies of measures,inadequate post-construction maintenance,and weak integration with ecological restoration efforts.Consequently,this paper proposes establishing a three-dimensional comprehensive system based on"zoned prevention and control,process interruption,ecological priority,and smart monitoring."This system emphasizes the synergy of source reduction,process control,and ecological restoration,as well as applying new technologies to enhance the precision in erosion control.It aims to provide theoretical reference and practical guidance for ensuring project safety and safeguarding the regional ecological barrier function.关键词
