我国生态城市建设的时空演化路径及其发展模式

The spatial-temporal evolution path and development patterns of eco-city construction in China

为了深入了解我国生态城市建设情况,更好地把握我国生态城市建设进程,通过对2000~2011年期间我国拟建生态城市的数据收集与分析,发现我国生态城市建设的演化进程具有两个明显特征:我国生态城市建设随着时间推移经历了一个离散-集聚-离散的倒U型空间演化过程;我国生态城市的分布具有明显的空间差异性。同时,根据我国生态城市发展的时空演化路径,提出生态城市建设的四个构建模式--空间散点模式、空间集聚模式、空间溢出模式与空间平衡模式。这四个模式是我国生态城市从无到有的发展过程。本文的研究结果可以加深对我国生态城市建设状况的认识,更好地把握我国生态城市建设的进程,从而为生态城市建设的合理开展提供决策参考。

In order to know well the eco-city construction and further understand the evolution of eco-city construc-tion in China,this study collects the data of ecological city during the period of 2000？2011,and our findings indi-cate that there are two obvious features in the evolution process of China＇s eco-city construction by data collection and analysis of ： the spatial distribution of ecological city in China has experienced an inversed U type （ discrete- ag-glomeration-discrete ） evolution; the distribution of China＇s eco cities show obvious spatial diff erence. Meanwhile, according to the temporal and spatial evolution path of China＇s eco city development,weput forward four patterns of eco city construction-discrete distribution pattern, combining point pattern, spatial agglomeration pattern and spatial spillover pattern. These four patterns reflect the development process of the ecological city in China. T he re-sults of this paper can deepen the understanding of the status of China＇s eco city construction, and better grasp the process of ecological city construction, so as to provide decision-making suggestions for the ecological city construc-tion in China.
