摘要
在回顾中外生态城市研究进展的基础上 ,提出以人为本 ,自然协调 ;因地制宜 ,规模适度 ;完善高效 ,园林绿化 ;整体协同 ,良性循环等生态城市空间结构优化组合的原则和“绿心组团网络式”城市空间结构模式。并以襄樊市为例进行实证分析。最后结论为生态城市是城市发展的必然趋势 ;构建城市发展引导机制 ,使城市建设逐步转向更加适宜人们居住的生态城市 ;“绿心组团网络式”城市空间结构是比较理想的生态城市空间结构模式之一。
Based on progress reviews the of eco city study at home and abroad,the rules of optimization and reorganization of spatial structure of eco city and 'the green center with around groups network spatial structure model' was put forward taking Xiangfan as a case First, the present eco city's research status and successful practices abroad, and the concept of eco city, the urban eco areas dividing, planning and design, the evaluation index system and other theories and methods of eco city in China since the 1980s were reviewed Second, the authors put forward the rules based on those reviews, which guide the optimization of spatial structure of eco city They are: ① to perform natural harmoniousness fundamental to human; ② to develop at an appropriate scale and suit measures to local conditions; ③ to practise landscaping and achieve perfection and high efficiency;and ④ to pursue overall coordination and benign circulation And with these rules, the authors commend a new model of spatial structure named 'the green center with around groups network spatial structure model'. Third, based on the analysis of the evolution and problems of its spatial structure, four development forms of urban land use were compared and urban land use for construction were comprehensively evaluated Combining population prediction, the authors suggest that the regional function collaboration of the peripheral area with Xiangcheng and Fancheng should be strengthened, and the planning idea of 'a continent, three mountains, three rivers'should be stressed to guide the city change to the green centre with around groups network spatial structure in the process of optimization and reorganization of spatial structure for creating a modern ruralizing eco city Finally, a authors think that the eco city is an inevitable trend of city development; the establishment of the city development leading mechanism makes the city turning gradually to an eco city that is more suited to human settlement;and green centre with around groups network spatial structure model is one of the ideal urban spatial structures
