【摘要】 在城市发展的过程中,随着城市功能的不断深化和扩展,用地规模的不断扩张,社会-经济-生态三子系统在各自动态发展的过程中形成了彼此间的耦合关系。环境友好型城市建设的目标和内涵,正是要求城市在向更高发展水平前进的同时,协调与维持这种良性循环的耦合关系。目前环境友好型城市虽然已成为指导城市发展的重要理念,但与其相关的研究一直停留在概念与内涵探讨的层面。而在城市规划与建设过程中,如何将理念变成可用于指导实践的工具,这就对科学研究提出了迫切的要求。这正是开展本研究的出发点。通过构建符合环境友好型城市内涵要求的评价指标体系,将环境友好型城市的发展目标量化,从而可以为城市规划建设提供可行的对策建议。今天的上海市宝山区,在确定以环境友好型城区为发展目标的同时,同时也经历着高密度的社会经济生态活动,从而对其内部的经济-社会-生态复合系统产生着显著的影响,由此在本研究中成为研究环境友好型城市复合生态系统耦合关系的典型案例。建立上海市宝山区社会-经济-生态复合生态系统耦合关系评价指标体系,通过对其以“十五”为主的七年时间(2000-2006)系统耦合过程动态变化的研究,探讨其子系统间耦合发展的内在机制。在指标体系中,最终的评价结果包括两个方面:其一是城市发展水平综合指数,这是从量的方面反映区域经济-社会-生态各方面发展的水平;其二是复合系统耦合水平综合指数,这是从质的方面反映区域经济-社会-生态符合系统彼此间相互协调促进的关系。两者共同反映了研究区环境友好型城市发展的水平。评价结果显示,在2000-2006年的区域发展过程中,随着区域整体发展水平的不断增强,宝山区复合生态系统内的耦合水平表现出先降低后升高的特性。早期的宝山区,作为上海配套工业基地,在较低的区域综合发展水平下,系统内部有着较高的耦合度,但这仅属于环境友好型城市建设的起步阶段。之后的2002-2004年,宝山区经济与生态系统获得迅速的发展,而对应的社会子系统发展相应落后,三者间的差距造成2003、2004年的区域复合系统耦合水平的下降。但同时,区域整体发展水平的提高则为宝山区进一步的发展打下了基础,如今,宝山区正处于建设高水平、高耦合的环境友好型城市的过渡阶段。此外,宝山区作为此次研究的实证案例,在对其进行调查研究的基础上,本研究亦试图在综合现状评价的基础上,为宝山区的区域转型和社会-经济-生态协调可持续发展的目标提供战略对策。更多还原

【Abstract】 During the urban development, the social-economy and eco-environment subsystems have formed a coupling relationship with the development of urban function and spread of land-use scale. So, the essential target of environment-friendly city is to maintain such a kind of fine coupling relationship while the city is in the step to a higher level.Nowadays environment-friendly city became an important theory to guide the urban development, but related researches are mostly around its concept and connotation. So, in process of urban planning and construction, an exigent require would been given to science research that how to convert such a concept into effective implements. It is the first reason for this research. By establishing evaluation index system for environment-friendly city, the development targets would be quantitative and easy to operate.As a district of Shanghai, Baoshan is in its way for "environment-friendly Baoshan", and also experienced the high-density social-economy-ecological activities, which cause notable impact to the complex system, therefore it is choosed as representative cases for study of coupling relationship evaluation in compound ecosystem for environment friendly city. Based on the national economic and social data (2000-2007) of Baoshan, internal mechanism in coupling development has been explored by the evaluation index system. The evaluation results included two comprehensive indexes: for urban development level evaluation and complex ecosystem coupling level evaluation. Two indexes reflect the quantity and quality of urban development respectively.The evaluation results showed that in the regional development process of 2000-2006, as the region’s overall level of development growed up continuously, while the complex ecosystem coupling level firstly decreases and then increases. The characteristic would be explained by Baoshan’s unique development course and its functional orientation evolution, which is changed in these years from the industrial base of Shanghai to an environment-friendly region.更多还原
