知识与生态关联视角下的城市新区空间发展研究：以珠三角区域4个战略性新区为例

As a response to the knowledge economy and sustainable development backgrounds，this research tends to explore spatial strategies which adapt to the current stage and meanwhile fit the space inherent law, both in theory and practical application. In theory research, this project is discussed in accordance with four key questions as follows. First, confirm the phenomena and trends that knowledge factors are highly correlated with ecological factors through systematic qualitative and quantitative related studies. Then, establish the knowledge-eco-interrelated development model through gray system technology and multivariate statistical analysis with the method of SAS（Statistical Analysis System）. The third issue is, definite the concept and development index system of “knowledge-eco district”. Fourthly, with the guidance of EOK（Ecology of Knowledge） methodology, this dissertation set up DICEFX（Distribution、Interaction、Competition、Evolution、Fluent）spatial development theoretical model referring to ecological models in the field of knowledge management. After that, interpreting and verifying the theory is carried out. What we expect is to focus on spatial development characteristics and trends such as affecting factors, pattern, organization, layout, structure, morphology in brand new perspective. And new spatial planning principles and methods is further proposed. In applied research, the above theory is applied to planning and construction practice of four strategic new district in the Pearl River Delta region. On one hand, we intend to formulate spatial development strategy outline respectively, thus the objective of knowledge-eco-interrelated development is obtained in a certain degree. On the other hand, the research applied to study the interaction between space requirements and space supply, probe the space optimization mechanism which adapt and further promote economic and social development, points out spatial planning approach and strategy of different spatial scales and different knowledge industry clustering. The results of applied research can provide a reference for the development of other new urban districts. The project has made innovative breakthroughs in data collection and analysis, correlation study, spatial development theory.

基于对知识经济和（生态）可持续发展这两大城市发展背景的响应，本项研究通过关联研究确认知识与生态关联发展的现象与趋势，运用SAS多元统计分析与灰色系统技术构建知识与生态关联发展模型；定义知识生态新区的概念并建立知识生态新区发展指标体系；借鉴知识生态学方法论，以知识管理的生态理论模型为原型构建DICEFX知识生态新区空间发展理论并进行阐释与实证检验，以全新的视角来研究城市新区的空间影响要素、模式、组织、布局、结构、形态等特征与趋势，变革传统的空间规划原则与方法。将上述理论与方法应用于珠三角四个战略新区的规划建设实践，得出其空间发展策略纲要，判研其空间需求与空间供给（规划方式）的互动关系，探寻适应并能推动经济社会优化发展的空间作用机制，梳理不同空间尺度与知识产业聚类的新区空间规划策略。研究在数据采集与分析、关联度研究、空间发展理论等方面做出了创新性的突破，开拓了规划本体空间领域一个新的研究方向。

知识经济和生态可持续发展是当前城市发展的重要背景，城市空间是城市发展的载体，也是规划学科研究的本体领域。基于对城市发展背景的响应，本研究指出城市空间发展应该打破固有特征与惯性模式，换一种视角来探讨与之相适应的组织方式，这涉及多种选择和不同路径。研究发现知识经济与生态可持续发展的核心要求有内在关联性，通过大量关联研究确认这一关联态势，运用SAS多元统计分析与灰色系统技术构建知识与生态动态关联发展模型；界定知识生态新区并建立知识生态新区发展指标体系；借鉴知识生态学方法论，以知识管理的生态理论模型为原型构建DICEFX知识生态新区空间发展理论并进行阐释与实证检验，研究该类新区的空间影响要素、发展模式、空间组织、规划布局、空间结构与形态等特征与趋势，与之相适应，传统的空间规划原则与方法也随之变革。将上述理论应用于珠三角四新区的规划建设实践，判研其空间需求与空间供给（规划方式）的互动关系，探寻适应并能推动经济社会优化发展的空间作用机制，梳理其基于知识经济发展的空间职能演化；基于互动与分布的用地分类、结构与布局优化；基于互动与竞争的混合兼容开发模式；基于演化与竞争的自然生态空间保护与发展；基于多维空间发展的虚拟空间与实体空间互动发展策略。研究取得的关键数据和重要结果如下：获取了32个知识生态新区的14项核心知识表征指标和19项生态表征指标数据，验证了知识与生态的显著灰色关联度。使得可以从生态学成熟的原则出发，去构建适应新生的知识经济内在要求的城市空间组织。构建了知识生态新区发展的空间模型，整理了一套用于系统挖掘其空间形态的大数据研究方法（数据获取、坐标转换、数据清洗、编程解析、Ward聚类），获取并处理了包括珠三角四新区的16个知识生态新区的用地、交通、形态、肌理等150余万条空间数据，聚类解析并提出分类规划策略。研究在数据采集与聚类分析、空间发展模型构建等做出了创新性的突破，开拓了规划本体空间领域一个新的研究方向。
