Micro-Renewal Design of Typical Public Spaces from the Perspective of Residents’Activity Characteristics and Spatial Needs:Taking Baizhifang Street in Xicheng District as an Example

As China’s urbanization development direction has shifted from incremental construction to upgrading existing structures,urban renewal has become an important planning approach,and the gradual micro-renewal model has become a key trend for residential area transformation.Additionally,the local renewal approach focusing on public spaces of residential areas is becoming a new way to enhance the quality of urban public spaces,stimulate urban vitality,and promote sustainable development of regions.Currently,due to the long building years and other factors,old communities have insufficient public facilities,parking difficulties,outdated facilities,and other problems,making it difficult to meet the needs of residents’lives.This paper takes Baizhifang Street in Xicheng District as an example and starts from the meaning of participatory design,respecting the existing environment and policies in China,discussing the public space problems,selecting the renewal area and formulating design strategies,and finally showcases the actual application of the design in public space renovation.

Urban Chemical Industrial Cluster Area Restructuring and Determinants: A Case Study of a Typical Old Chemical Industry Area Along the Yangtze River, China

China is in a transitional period between urban renewal and industrial change.In this period,the focus has been on the suburbanization of enterprises and land transformation in old industrial areas,particularly areas with chemical industries.A life cycle theoretical framework was established to develop chemical industrial zones in the context of urban expansion and land function conversion.The long-term historical processes and mechanisms that transformed a typical old chemical industry area along the Yangtze River,Yanziji Area of Nanjing City were unveiled and comparatively analyzed.The study found that the entire life cycle of the case study area was formed through the combined action of different influencing factors.Traditional industrial location factors played important roles during the rise and continuity of the chemical industry zone,while unconventional environmental regulations and government policies drove its decline and transformation.In the transformation of the old chemical zone,the renewal and redevelopment of industrial land into higher-value residential land is a key link determining the feasibility of government fund compensation and the circulation of capital.These findings demonstrate that regional control and environmental regulation play crucial roles in determining the location of polluting industries and the renewal of urban industrial areas.This research enhances the understanding of the development history and reconstruction of chemical industry clusters and plots within megacities at a finer geographic scale.

为更新而租地——重新审视政府主导型租地更新模式

面对外部产业转移和内部要素价格上涨的压力,以城乡二元结构为背景的工业化已经难以适应高质量发展需求,面临转型发展的巨大挑战。作为工业化的主要空间载体,集体土地上旧厂房的改造成为释放产业空间的重要途径。在总结现有模式基础上,围绕土地产权构建分析框架,刻画旧厂房改造过程中各主体的权责关系,提出了政府租地更新的新模式,并以F市H科技城改造为例进行了案例研究。这一模式中政府成立公有性质的企业向村集体租地进行土地再开发,以土地租金的形式对村集体和村民进行补偿。租赁期满后,土地上的所有财产将全部返还给村民,实现政府、投资者和村民的多赢。跟以往模式相比,租地更新模式既保证了资本的正常运行,又发挥了各自的优势和特点,核心是低成本实现了土地产权正规化,提高了土地产权的实现度。

“三旧”改造政策延续性与适法性调整范畴及策略

《民法典》施行和《土地管理法》修订后,“三旧”改造政策存在着延续性与适法性调整问题,地方有关“三旧”改造及城市更新已陆续提出立法动议或已颁行某些规范指引,但就“三旧”改造暨城中村改造调适治理精准有效的配套立法规制不尽完善。这就要求地方政府推动“三旧”改造暨城中村改造工作须做好跟上位法的实施性衔接,有针对性地对施法文件进行相应调整。譬如,针对“三旧”改造用地之征收标准问题,对集体土地依法实行规模型征收的关键是明确成片开发认定标准;“三旧”改造依法履行“集转国”等征收程序且合乎法定条件,涉及征收依据、成片开发标准认定、城镇开发边界划定、“三地”征地审批程序等,均有特别的适法性规制要求,应与上位法规定进行衔接或补充细化;作为特别的政策安排,“三旧”改造用地可以协议出让,但其存续的合法性、合理性需要进行适法性阐释,且要把握合规性操作;可借鉴广东“三旧”改造政府统筹协调引入社会资金有序运作等重要经验。还应正视并应对征地拆迁难题,强化“三旧”改造征地拆迁矛盾之诉源治理,合理保障利益相关者的正当权益,构建防范处理“钉子户”问题的有效机制,重视协议解决征拆补偿问题,平衡各方主体利益,从源头化解“三旧”改造之征拆矛盾纠纷。
