【摘要】：中国的城镇化进程发展迅速,目前进入由规模扩张向质量提升的新型城镇化阶段。城镇化使城市系统复杂化,从而导致绿地系统内部要素、结构复杂化,外部与环境的关系密切化,这一切都为城市绿地系统规划提出了新的要求。绿地系统是一个开放性系统,除了系统内部要素之间的相互作用,该系统与外部环境之间还存在相互影响和相互制约。论文运用比较研究法发现与分析城市绿地系统规划中存在的问题,提炼城市绿地空间形态生成影响因素；运用演绎论证法辩证地看待现实与未来的发展规律与趋势,分析绿地系统要素之间的关系以及绿地布局结构与功能之间的关系,探索绿地系统空间形态发展过程及生成规律,提炼出绿地空间形态生成机制；将协同学理论应用到绿地系统规划之中,探讨基于绿地空间形态生成机制的城市绿地系统协同布局原理和规划方法；通过实践的检验,证明协同规划方法的科学性,同时发现问题,促进研究工作的进一步深化和完善。本论文研究内容与结果体现在以下4个方面： 1、归纳了城市绿地空间形态生成影响因子根据因子的显著性、全面性、系统性原则,从众多的影响城市绿地空间形态的因子中选择出主要的绿地空间形态生成因子,分为基础性因子、内源性驱动力和外延性引导力3个大类。基础性因子包括自然资源和人文资源,它们是构成城市绿地的骨架。内源性驱动力包括游憩功能需求、防灾避险功能需求、景观功能需求、生态功能需求,它们是绿地形成的原动力。外延性引导力包括社会环境、经济环境,引导了绿地的发展方向。 2、揭示了城市绿地空间形态生成机制提出了城市绿地系统是一种自组织和他组织复合发展的过程的观点,绿地系统在空间形态生成过程中,既通过自组织机制按自身规律发展演化,又通过人为调控,在外界直接干预下不断完善。其机制具体表现在3个方面：第一,遵从土地特性的适宜机制。绿地的分布受自然资源和人文资源的影响,起到保护资源的作用。第二,功能机理制约下的自组织机制。绿地在游憩、防灾避险、生态和景观功能机理制约下,并遵循功能协同原理,空间形态发生自组织现象,系统走向有序结构。第三,外部调控机制。社会和经济等外部环境是绿地空间形态生成的外源性引导力,调控和引导绿地空间形态的生成。本研究揭示的绿地空间形态生成机制,一定程度上属于填补空白性的工作,对城市绿地规划具有科学的指导作用。 3、建立了城市绿地系统功能协同布局模式基于绿地在游憩、防灾避险、生态和景观等各方面的功能协同作用机制,以多功能协同为目标,提出了一种能综合发挥城市绿地各方面功能、网络化的绿地系统布局模式。该模式使绿地服务范围可以覆盖整个市区,并使区级以上公园位于绿带之中,形成良好结构,同时能有效避灾,发挥绿地生态和景观功能。 4、形成了多方协调的绿地系统协同规划方法运用系统学理论,引入协同论观点,以绿地空间形态的生成机制为依据,提出机制导向的、系统内部功能之间协同及与外部环境协同的绿地系统规划理论和方法,是一种创新性的尝试。并在考虑与现行绿地系统规划纲要对接的基础上,将绿地功能体系分解为现行国标的绿地分类体系,使绿地系统协同规划方法具有可操作性。
[Abstract]:China's urbanization process is developing rapidly, and is now entering a new stage of urbanization from the expansion of scale to quality. The urbanization makes the urban system more complicated, resulting in the internal elements of the green land system, the complexity of the structure and the close relationship between the outside and the environment, which all provide new requirements for the urban green land system planning. The green system is an open system, in addition to the interaction between the elements within the system, there is also mutual influence and mutual system between the system and the external environment The paper uses the comparative study method to find and analyze the problems existing in the urban green space system planning, and to refine the influence factors of the urban green space form. The development law and the trend of the real and future development are treated dialectically with the deduction and demonstration method. The relationship between the elements of the green space system and the relationship between the layout structure and function of the green space is analyzed, the development process and the generation rule of the space form of the green space system are explored, the space form generation mechanism of the green space is extracted, and the synergetics theory is applied to the green land system planning. In this paper, the cooperative layout principle and planning method of the urban green land system based on the space form generation mechanism of the green space are discussed, the scientific nature of the collaborative planning method is proved through the practice test, the problem is found, and the further deepening and completion of the research work is promoted. Good. The research contents and results of this thesis are shown below 1. The spatial form of urban green space is summarized. the effect factor is generated according to the significance of the factor, The main green space form factor is selected from the factors that affect the spatial form of the urban green space, which is divided into the basic factors, the endogenous driving force and the epitaxial property. The basic factors include natural resources and human resources, and they are made up of The framework of urban green space. The endogenous driving force includes the demand of recreation function, the function demand of disaster prevention, the demand of landscape function and the demand of ecological function. They are green. the motive force of the formation, including the social environment, the economic environment, the guidance, The direction of the development of green space. The space form generation mechanism of the green space has put forward the view that the city green space system is a process of complex development of the organization and the organization, and in the process of the generation of the space form, the system of the green space is made by the self-organizing mechanism according to its own law. The evolution of the exhibition, through man-made regulation, is The mechanism is embodied in three aspects: first, A suitable mechanism for complying with the characteristics of land. The distribution of green space is affected by natural resources and human resources. In response, act as a protection resource. Second, the function The self-organizing mechanism under the restriction of mechanism. The green space is restricted by the mechanism of recreation, disaster prevention, avoidance, ecology and landscape function, and the function cooperation principle is followed, and the space form is self-organized. The system is in an orderly fashion. The external environment, such as society and economy, is the exogenous guiding force, regulation and control of the space form of the green space. The generation of the space form of the green space is guided. The space form generating mechanism of the green space, which is revealed in this study, is a kind of space-blank work to a certain extent, and it is of great importance to the urban green space. Planning has the guiding role of science. The function co-layout pattern of the urban green land system is based on the function cooperation mechanism of green space in the aspects of recreation, disaster prevention, avoidance, ecology and landscape. The seeds can be integrated into the various aspects of the urban green space The mode enables the green space service to cover the entire urban area and make the park more than the park in the green belt to form a good structure, and at the same time it can The invention has the advantages of avoiding the disaster, and playing the ecological and landscape function of the green space. The paper forms a multi-party coordinated planning method of the green land system, using the system theory, introducing the theory of synergy, and using the green space to empty. Based on the mechanism of the generation of the inter-system, the system-oriented and internal functions of the system and the green space in cooperation with the external environment are put forward. The system planning theory and method is an innovative attempt, and on the basis of considering the interface with the current green land system planning platform, the green space function system is decomposed into the current national standard green space classification body
