摘要
甘肃省河西地区生态环境脆弱,区域微地貌复杂,泥石流流域缺乏明显的分水岭。应用ArcGIS水文分析和人工解译的方法,确定河西地区单体泥石流流域范围,可为河西地区泥石流准确快速调查提供参考,为下一步的泥石流工程治理、监测预警等提供依据。
Hexi area in Gansu Province has fragile ecological environment and complex regional micro-topography,and there is no obvious watershed in the debris flow basin.The ArcGIS hydrological analysis and manual interpretation methods were used to determine the scope of a single debris flow basin in Hexi area,which can provide an effective reference for the accurate and rapid investigation of debris flow in the Hexi area,and provide a basis for the next step of debris flow engineering control,monitoring and early warning.
