【摘要】 20世纪末的信息革命促进了全球快速经济的发展,而CBD——作为经济发展的晴雨表,在西方纷纷复兴,在国内蓬勃开发。在机遇和挑战面前,CBD并呈现出综合化、生态化的发展趋势。作为一个经济、物质、信息、人口高度集聚的人工化生态系统,CBD本身是一个脆弱的生态非自律系统。面对环境、人口、经济、文化、价值、交通等以及信息革命的挑战,如何实现CBD的生态可持续发展成为一个重要的研究课题。论文借鉴生态学和系统观的基本思想与原理,通过前期对大量国内外CBD实例和当前CBD研究理论的研究分析,从分析当代CBD的特征、生态化发展趋势以及可持续发展所关注的核心问题入手(第二章),对CBD生态模型中支持子系统的城市系统的各个方面的可持续规划进行探索,包括:发展目标定位,功能系统,CBD结构,绿化景观、外部空间形态、交通系统、开发运作模式的可持续规划元素和实现途径的研究(第三章)。然后借鉴“生态承载力”模型来研究可持续CBD的合理规模(第四章)。探索如何在城市规划中促进并实现CBD生态可持续发展。更多还原

【Abstract】 The information revolution in the end of 20th boost the development of the world economy,at the same time,CBD——as the reflection of economy,burst into renaissance in the west and construction in china one after another. In face of the chance an challenge,CBD show on a compositive and ecologic trend of development.As an artificial and ecologic system with the feather of high centralization of economy、substance、information and population,CBD is a frail unself-discipline ecologic system. So that,in face of the challenge of environment、population、economy、culture、value、traffic and information revolution,it has become a important study to achieve the sustainability of CBD by urban planning.The study takes use of the basic idea and principle of ecology and system,and studies a lot of examples of CBD in and outdoors as well as theory about CBD,so as to find out the up—to—date CBD’S character、ecologic development trend and the basic subject which the sustainable CBD focus on at first.(in the second chapter) And then ,we study the sustainable planning of the CBD’S city system as a support subsystem of ecologic system,including the orientation of CBD、the function system、the structure of CBD、the green system、the outside space form、the traffic system and the exploitation,to find out the sustainable element and the approach of them. (in the third chapter) In the last,we study the approach to ascertain the scale of CBD by use of“ecologic sustainability”model. (in the third chapter) So as to explode the approach to sustainable CBD in urban planning.更多还原
