| 摘要: |
| 北京市第二道绿化隔离带郊野公园环是协调城市发展与自然环境的重要绿色载体，同时也是满足市民游憩需求以及提供城市安全保障的有效途径。基于第二道绿化隔离带郊野公园环建设在生态环境、服务对象、功能承载等多方面的复杂性及不确定性，研究探讨了情景分析的理论内涵及研究进程。构建落实《北京城市总体规划（2016年—2035年）》对第二道绿化隔离带基本建设要求的基础情景；以生态、游憩、安全3个目标为导向，以生境质量、固碳释氧、游憩服务、城市雨洪4个方面为关键因素进行定量分析，结合基础情景进行多目标导向下的郊野公园环规划模拟，并进行综合分析。为城市与自然协同发展背景下的郊野公园环的科学建设提供新的应对策略，也为具有复杂不可预测性的绿地系统规划提供新的思维角度。 |

| Abstract: |
| The second green belt country park ring is an important green carrier to coordinate urban development and natural environment in Beijing. It is also an effective way to meet the recreational needs of the public and provide urban security. This research explores the theoretical connotation and research process of the scenario analysis in the planning course. Based on the complexity and uncertainty of ecological environment, service object and functional bearing in the construction of the second green belt country park ring, it proposes to conduct a scenario planning study. Firstly, establish a basic scenario for the implementation of Beijing Urban Master Plan (2016—2035) for the basic construction of the second green belt. Secondly, carry out quantitative analysis guided by the three goals of ecology, recreation and safety, around the four key factors of habitat quality, carbon sequestration and oxygen release, recreation services, and urban stormwater. Combined with the basic scenario, it conducts a multi-object-oriented country park ring planning simulation and comprehensive analysis. This research provides new strategies for integrated scientific construction of the country park ring in the context of coordinated development of the city and nature. It also furnishes new thinking perspectives for the planning of complex and unpredictable green space systems. |
