| 近年来,随着城镇化的快速发展,城市水土流失问题日益显著。城市水土流失可引起管道淤积、风沙扬尘、水源污染、环境破坏等诸多危害,已成为新时代水土保持高质量发展面临的一个重大问题。当前,对于城市在建项目水土流失研究较多,但针对城市建成区的水土流失研究较少,尤其对于城市建成区水土流失定量估算方面几近空白。本文以已建成的居民区、公园、水务工程等为研究对象,系统分析建成区雨季水土流失特征,并以实测水土流失数据为基础,通过综合调整参数的研究设置,提出了适用于城市建成区的水土流失量定量估算方法,旨在为城市水土保持科学研究、城市水土流失预防与治理、城市水土保持设施设计和精细化监管提供参考。 |
| 英文摘要: |
| Urban soil erosion can cause various hazards such as pipeline siltation, sandstorms, dust, water source pollution, and environmental damage, and has become a major issue facing the high-quality development of soil and water conservation in the new era. Currently, there are many studies on soil erosion in urban construction projects, but there is relatively 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 highways, 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. |
