摘　　要：优化流域各尺度间蓝绿空间的嵌套构建与协同规划技术,有助于解决丘陵城市规划中蓝绿空间破碎、边界模糊、管控粗放等问题,为蓝绿基础设施规划得到有效传导和合理实施提供具体手段。研究构建了“次流域—小流域—次小流域”各尺度间蓝绿空间协同优化的框架,提出了多尺度蓝绿空间网络构建的规划路径以及“衔接点—衔接结构—衔接单元”识别的关键技术。以川中丘陵地区的典型城市资阳为例,对多尺度蓝绿空间协同规划框架、技术路径及关键技术的应用进行示例,为后续蓝绿基础设施规划和建设提供技术参考。By systematically planning and constructing blue-green infrastructure,people can better leverage the comprehensive benefits of blue-green space and improve the stability of urban and rural ecosystems.At present,the most common problems are related to the fragmentation of blue-green spatial planning and control as well as the lack of systematic infrastructure construction.These problems exists in different watershed scales and in-between urban-rural areas.The blue-green infrastructure construction of hilly cities is more strictly constrained while the edge features of the blue-green space in hilly cities are more complex.Distinct characteristics at different watershed scales also makes it more difficult to integrate and define boundaries in hilly cities.From the view point of scale,the existing researches of blue-green space in China is in the process of transitioning from a single scale to multiple scales,and the technical methods and guidelines are still limited to a single scale.Currently,it is necessary to optimize the nesting and construction of blue-green spaces between different scales in the watershed,and explore collaborative planning paths and technical methods.In response to the characteristics of blue-green space in hilly cities,this study constructed a framework for collaborative optimization of blue-green space at various scales of“sub watershedsmall watershed-sub small watershed”.It also proposed a planning path for constructing a multiscale blue-green space network and key technologies for identifying and nesting“connection pointconnection structure-connection unit”.At the sub watershed scale,blue-green network recognition is carried out based on ecological security and multi factor comprehensive evaluation.As for the scale of small watershed,resistance surface recognition is carried out based on Morphological Spatial Pattern Analysis,landscape connectivity evaluation,land refinement classification,and nighttime light correction.This achieves the identification and nested optimization of ke
