摘要
生态清洁小流域的建设对河湖生态环境的保护与涵养、生态环境的恢复、科学开展国土绿化、建设宜居宜业的美丽乡村等方面都有着十分重要的意义。该研究以广东省广州市从化区为研究区域,基于DEM数据,通过ArcGIS技术将境内水源保护区、农业发展区、生态旅游区、城镇宜居区等划分为85条生态清洁小流域,划定为水源保护型、绿色发展型、和谐宜居型和生态旅游型4种类型,并探索其适宜的小流域建设模式,可为后续生态清洁小流域规划设计提供参考。
The construction of ecologically clean small watershed plays an important role in protecting and conserving water sources,reviving the ecological environment of rivers and lakes,scientifically carrying out large-scale national greening actions,and building a livable,suitable and beautiful countryside.This study takes Conghua District of Guangzhou,Guangdong Province as the research area.Based on DEM data,85 ecologically clean small watersheds in Conghua District of Guangzhou are divided into water source protection areas,agricultural development areas,eco-tourism areas and urban livable areas through ArcGIS technology.It is classified into four types of ecologically clean small river basins:water source protection type,green development type,harmonious livable type and ecotourism type,and the appropriate small river basin construction mode is explored to provide reference and discussion for the subsequent planning and design of ecological clean small watershed.
