摘　　要：【目的】区域河流蓝绿空间内在自然过程和空间功能紧密联系,在国土空间规划中发挥着多尺度支撑约束作用和多维度区域协调作用,其协同规划研究对探讨国土空间规划背景下最大效益地保护和开发自然资源具有重要意义。【方法】通过文献与实证研究,归纳区域河流蓝绿空间转化的特征差异,即内在自然特征差异、外在建设发展诉求差异,以及区域整体空间转化特征差异;然后在此基础上总结针对上述差异特征的规划思路。【结果】提出区域河流蓝绿空间在空间与功能上的协同规划管控途径,即划分整体空间、纵向空间和横向空间三级样条分区,并协调安排分区复合功能;依据样条分区功能目标,在“城乡区域-河网、中心城镇-河区、街区场地-河段”3个层面制定河流蓝绿空间的协同规划与管控措施。【结论】区域河流蓝绿空间协同规划既注重适应河岸生态系统的演进,又注重满足建设发展需求和邻近建设用地的环境影响,在保障河流蓝绿空间生态系统健康的同时提升了外部复合服务功能。[Objective]Passing through nature reserves,rural agricultural areas and urban construction areas successively,regional river blue-green space is typically characterized by external differentiation and internal integrity.With its natural process and spatial function closely linked,regional river blue-green space plays the role of multi-scale support constraint and multi-dimensional regional coordination in territorial spatial planning.As an important ecologically sensitive space,regional river blue-green corridor network can support the supply of territorial natural ecological resources as a whole,the protection and restoration of ecological space,the efficiency of rainfall flood regulation and storage,the health of ecosystem in urban and rural watersheds,and can constrain the unlimited sprawl of city and the planning and spatial layout of construction land to guide the formation of sustainable urban spatial forms and promote the intensive development of territorial space.The river blue-green space has multiple functional values in such fields as ecology,society,economy and culture.Through reasonable planning and management,the river blue-green space can be used as a“connector”to coordinate the conflicts between protected areas and development areas,construction land and non-construction land,ecological function and social function,etc.The research on the collaborative planning of river blue-green space is of important significance to the conservation and exploitation of natural resources under the background of territorial spatial planning.[Methods]Through literature research and case studies,this research summarizes the differences in the transformation characteristics of regional river blue-green space,and develops approaches for the collaborative planning and management thereof.[Results]The differences in internal natural characteristics are reflected in longitudinal spaces(such as source zone,transfer zone and sedimentary zone),lateral spaces(such as river channel,flood plain,slope area and highland area)
