Prevention and Control Regionalization and Countermeasures Against Erosion in Beijing

北京山区水土流失严重,山洪、泥石流灾害时有发生。根据防护目的、土壤侵蚀强度和土壤侵蚀潜在危险度等,应用地理信息系统技术,采用人机交互判读分析方法,将水土流失防治区划分为重点预防保护区、重点监督区和重点治理区,并提出北京地区水土流失防治对策。

There are serious soil erosion problems in Beijing mountain area, where floods and debris floods happen frequently . Prevention and control areas of soil erosion in Beijing have been divided into three parts: Prevention and Protection areas, Monitoring areas and Control areas, based on protection purposes, soil erosion intensity and potential erosion danger, with technologies of GIS.
