摘要: 寒区城市面临冬季寒冷和城市病的双重挑战，特别是寒区大城市，在生态本底相对脆弱的情况下，还要面对巨大的人口压力。提高城市生态承载力、增强城市韧性，是寒区城市可持续健康发展的合适方向。通过分析寒区城市面临的特殊挑战，梳理已有研究和规划实践经验，结合城市生态韧性“规模—密度—形态”的研究和调控框架，提出一系列规划策略。其中，基于规模韧性的策略包括控制城市增长边界、高标准建设生态基础设施、重视常绿植被配置，基于密度韧性的策略包括控制城市密度、调节组团密度、增加冬季环境状况作为密度控制补充依据，基于形态韧性的策略包括优化城市外围形态、促进城市多中心组团发展、设置更多可接近的蓝绿空间、针对冬季需求采用更细致的规划布局手段等。
Abstract: Winter cities are faced with the dual challenges of cold climate and urban diseases. With a relatively fragile ecological background, they are also faced with huge population pressure. Improving urban ecological carrying capacity and enhancing urban resilience is the appropriate direction for the sustainable and healthy development of winter cities. By analyzing the special challenges faced by winter cities, combing the existing research and planning experience, and combining the research and regulation framework of "scale-density-morphology" of urban ecological resilience, a series of planning strategies are proposed. Among them, strategies based on scale resilience include controlling urban growth boundaries, building ecological infrastructure with high standards, and attaching importance to the allocation of evergreen vegetation. Strategies based on density resilience include controlling urban density, adjusting internal group density, and increasing winter environmental conditions as the supplementary basis for density control. Strategies based on morphology resilience include optimizing the urban periphery form, promoting the development of urban polycentric clusters, setting up more accessible blue-green spaces, and adopting more detailed planning and layout methods for winter needs.
