现代中国城市生态规划演进及展望

文章将1949年以来的中国城市生态规划演进过程分为初始萌芽期、缓慢发展期、启动建构期和全面发展期四个阶段。将社会经济环境与城市生态规划予以关联考察,从理论与实践两方面归纳了中国城市生态规划的演进特征,分析了中国城市生态规划存在的主要问题。在认知中国生态环境发展趋势的大背景下,从主动适应空间规划体系改革、提高城市生态规划的应需性水平、多向度拓展城市生态规划的生态位、探索城市生态规划体系创新、建构具有中国特色的城市生态规划理论与实践体系五个方面对未来中国城市生态规划的发展进行展望。     

儿童友好型社区营造中的参与者社会网络构建与分析 —以湖南省长沙市育才第三小学"娃娃农园"营造实践为例

Introducing the case of the Kids’ Gardens in Yucai No. 3 Primary School in Changsha City, Hunan Province, this study established sociograms upon the contact-frequency-based network with UCINET to systematically analyze the characteristics of different participants in the process of the childfriendly community building and the varying pattern of all social relations, aiming at addressing problems emerging in public participation and multi-stakeholder collaboration in Chinese mainland. It was found that by bonding stakeholders including citizens, the government and party organizations, universities, and public institutions and enterprises, this practice encouraged the school — as a community — to leverage its internal resources. The school finally overcame the organizational inertia and achieved independent operation and growth during the process of community building. The study also demonstrated that the social network of participants was developed and defined with both independent and dependent modes from an overall perspective, of which the former characterized for its dominant internal ties and a dense tree-like hierarchical management structure might be more efficient. From a participant perspective, the brokerage roles in key nodes were critical to the community building. Finally, spatial design strategies, including enhancing the spatial affordance to serve diverse activities, space zoning and allocation, offering “half-done” spaces, and phased development, were provided for similar community building practice.     

流量驱动的当代城市空间再生产研究 ——以上海市愚园路地段城市更新为例

移动互联网逐步普及和金融系统化 改革的双重影响下,传统城市更新的空间再 生产发生转变。研究旨在揭示流量驱动下城 市更新新范式的空间生产逻辑,解释资本在 该过程中的内在循环机制。基于相关文献研 究和对空间生产理论的演绎,提出流量取代 容量成为城市更新的核心目标,市场估值取 代资产价值成为城市更新中资本盈利的核心 手段,新范式下的城市更新呈现出以场所精 神吸引流量、以内容运营创造流量、以快闪 营销维持流量的特征;选取上海市愚园路的 更新实践作为案例,通过对更新过程中流量 运营的策略研究,对流量驱动下的城市更新 新范式的空间生产逻辑进行印证,并进一步 展望流量驱动下的城市更新未来实践和理论 研究的探索方向。     

社会网络方法在城市更新研究中的应用现状及潜力探索

城市更新涉及多方利益相关者的动态博弈,研究者运用社会网络技术方法,量化分析多方行动者关系网络与更新实践的互相影响,为更新实践提供策略指引。文章对我国城市更新领域学者应用社会网络方法的文献进行检索,针对文献在社会网络相关理论与技术方法方面的应用,探讨社会网络方法在城市更新研究的应用现状、有效性和不足,并探索未来发展趋势。研究发现,社会网络方法能揭示行动者关系、权力结构和信息流动,评估行动者对更新的贡献和影响,促进协商与合作,推动可持续更新,在城市更新研究中具有广阔的应用潜力,未来研究可加强理论框架构建,并结合新技术提高数据收集和分析能力,为城市更新实践提供更加科学有效的决策支持。
