【摘要】：城市化的快速发展使城市面临着一系列环境灾难与社会问题,传统规划方法已无法协调生态保护与城市化发展的关系。景观都市主义作为新的规划设计理论与策略,能有效缓解传统城市开发面临的严峻形势,它不仅能积极应对城市化发展,同时还能保护自然生态环境。本文在理论研究方面,通过对相关理论、案例的研究,梳理了景观都市主义的发展历程、理论和实践方式,实践方式包括景观作为绿色基础设施、工业废弃地的改造与更新、自然过程作为设计形式等。针对自然、城市、人类系统的非线性特征,以非线性理论中混沌理论、分形理论、自组织理论对规划设计领域的启示,拓展和深化景观都市主义的应用体系,并形成相应的实践策略,包括景观都市主义计划性策略、景观都市主义修复性策略以及景观都市主义嫁接性策略。在实践应用方面,立足于成都“北改”工程中凤凰山片区的改造,以绿色基础设施为研究对象,从水平层面和垂直层面对凤凰山片区的景观空间格局进行了分析。水平层面的分析包括：景观资源的解构分析、开放空间格局分析、景观系统结构的辨识与分析；垂直层面的分析为景观单元的土地利用价值分析。其中应用了解构主义、图底分析法、关联耦合、分层叠加法力求为其后的规划设计找到科学的依据。在分析结果的基础上,以非线性理论下景观都市主义的应用为指导,得出了以下成果：(1)实现绿色基础设施网络化构建。非线性理论的影响下将城市看做不确定、混沌的非线性系统,因而凤凰山片区的绿色基础设施网络化构建采用的是一种长期、动态的计划性策略即“绿网计划”,力求弹性的适应城市化发展的“不确定性”,这种方式将有别于现如今形式性的线性“静态”规划方案。(2)针对“绿网计划”中涉及的绿色基础设施提出相应的保护与更新策略。根据片区绿色基础设施面临的现状,以非线性理论对规划设计领域的启示指导实践,使构建的综合实践体系在项目中加以应用。因为非线性理论同时也蕴藏着动态的生态理念,所以在复兴策略中,有应用可持续性景观设计、参与性景观设计等多种前沿的设计手法。(3)与成都“北改工程”现有形成的传统规划方案做对比,论证得出实践策略的意义。说明了在面对城市扩张所带来的一系列生态问题、自然灾害以及社会问题时,传统的规划设计方法已被证明是盲目、浪费、仓促的线性开发模式。而非线性理论指导下景观都市主义能积极应对城市混乱、无序和环境危机的挑战,且又能做到保护与开发兼顾。这种基于非线性理论构建下的景观都市主义综合的实践形式,力求为“北改工程”乃至其他区域绿色基础设施的构建与改造提供参考。
[Abstract]:With the rapid development of urbanization, cities are faced with a series of environmental disasters and social problems. The traditional planning methods can not coordinate the relationship between ecological protection and urbanization development.Landscape urbanism, as a new theory and strategy of planning and design, can effectively alleviate the severe situation of traditional urban development. It can not only actively respond to the development of urbanization, but also protect the natural ecological environment.In the aspect of theoretical research, this paper combs the development course, theory and practice mode of landscape urbanism, including landscape as green infrastructure, transformation and renewal of industrial wasteland, through the relevant theories and case studies.Natural process as design form, etc.In view of the nonlinear characteristics of natural, urban and human systems, the application system of landscape urbanism is expanded and deepened by the enlightenment of chaos theory, fractal theory and self-organization theory to the field of planning and design.And form the corresponding practical strategies, including landscape urbanism planning strategy, landscape urbanism repair strategy and landscape urbanism grafting strategy.In practice and application, based on the reconstruction of Fenghuangshan area in Chengdu "North Reform" project, the landscape spatial pattern of Fenghuangshan area is analyzed from horizontal and vertical aspects, taking green infrastructure as the research object.The horizontal analysis includes the deconstruction analysis of landscape resources, the analysis of open space pattern, the identification and analysis of landscape system structure, and the analysis of vertical level is the land use value analysis of landscape unit.Among them, deconstruction, bottom analysis, correlation coupling and stratified superposition are used to find scientific basis for planning and design.Based on the analysis results and guided by the application of landscape urbanism in nonlinear theory, the following results are obtained: 1) realizing the construction of green infrastructure network.Under the influence of nonlinear theory, the city is regarded as an uncertain and chaotic nonlinear system, so the green infrastructure network construction in Fenghuangshan region adopts a long-term and dynamic planning strategy called "Green Network Plan".In order to adapt to the "uncertainty" of urbanization development flexibly, this way will be different from the linear "static" planning scheme of the present form. It will put forward the corresponding protection and renewal strategies for the green infrastructure involved in the "Green Network Plan".According to the current situation of green infrastructure in the region, the practice is guided by nonlinear theory in the field of planning and design, and the integrated practice system is applied in the project.Because the nonlinear theory also contains the dynamic ecological concept, so in the strategy of rejuvenation, there is the application of sustainable landscape design.The participatory landscape design and other advanced design techniques are compared with the existing traditional planning scheme of Chengdu "North Reform Project", and the significance of practical strategy is demonstrated.In the face of a series of ecological problems, natural disasters and social problems brought by urban expansion, the traditional planning and design methods have been proved to be blind, wasteful and hasty linear development models.Under the guidance of nonlinear theory, landscape urbanism can deal with the challenges of urban chaos, disorder and environmental crisis.This comprehensive practice form of landscape urbanism based on nonlinear theory aims to provide a reference for the construction and transformation of green infrastructure in the "North Reform Project" and other regions.
