城市水土流失特征与土壤侵蚀量定量估算OA

Urban soil erosion can cause various hazards such as pipeline siltation,sandstorms,dust,water source pollu-tion,and environmental damage,and has become a major issue facing the high-quality development of soil and water con-servation in the new era.Currently,there are many studies on soil erosion in urban construction projects,but there is rela-tively little research on soil erosion in completed projects,especially in terms of quantitative estimation of soil erosion in urban completed projects,which is almost blank.This article takes different types of urban completed projects such as high-ways,water engineering,residential areas(business districts),and parks as research objects,systematically analyzes the characteristics of soil erosion in built-up areas,and based on measured soil erosion data,proposes a quantitative estimation method for soil erosion in Beijing's built-up areas through a combination of measured and empirical formulas.The aim is to provide reference for scientific research on urban soil and water conservation,prevention and control of urban soil and water loss,design of urban soil and water conservation facilities,and refined supervision.
