秦巴山脉区域城乡空间流域化发展策略

Urban and Rural Space Development in Qinba Mountain Area Based on Basins

秦巴山脉区域是我国生物多样性保护与水源涵养重要区,也是南水北调工程的重要水源地,区域山形水势相互交织、山地水文过程显著,呈现出典型的流域化发展趋势。本文分析了秦巴山脉区域城乡空间发展的现状及存在问题,阐述了区域城乡空间流域化发展的必要性;以流域为分析视角,以多尺度流域基底划定为依据,确定了秦巴山脉区域流域等级体系框架和五级流域划分;提出了秦巴山脉区域城乡空间发展策略——以流域生态管控为基础的城乡结构,以流域绿色转型为导向的城乡模式,以流域联动发展为组织的协同管控。研究表明:流域作为秦巴山脉区域典型的生态单元,与城乡空间发展的耦合程度较高;以流域为载体的城乡空间规划与制度管控有助于促进秦巴山脉城乡绿色循环发展。

The Qinba Mountain area is an important area for biodiversity protection and water conservation in China,and also an important water source for the South-to-North Water Transfer Project.Mountains and rivers are intertwined in this region,and the hydrological process is closely related to the mountainous environment,showing a typical trend of basin development.This study analyzed the current situation and existing problems in the urban and rural space development in this region,and elaborated the necessity of basin development.Meanwhile,we defined the basin order framework and five-level basin division in the Qinba Mountain Area,from the perspective of basin analysis and based on the delineation of multi-scale basin basement.The urban and rural space development strategy in the Qinba Mountain Area is proposed,namely an urban and rural structure based on basin ecology management and control,an urban and rural pattern guided by green transformation of basins,and collaborative management and control centering on interactive development of basins.The results show that basin is a typical ecological unit in the Qinba Mountain Area and is highly coupled with the urban and rural space development.Urban and rural space planning and institutional control based on basins is conductive to the green development of the Qinba Mountain Area.
