The Spatial-temporal Pattern and Its Driving Mechanism of Eco-city Construction in China
通过分析360个中国生态城市案例的时空分布，发现城市规模和经济是主要驱动力，而生态环境影响较小。
In order to the better understanding and judgment of China′s eco-city construction activities in present,and grasp the process and internal mechanism of eco-city construction,this paper has collected a lot of eco-city construction cases in China,and analyzed the spatial-temporal pattern and its driving mechanism of eco-city construction in China by means of density surface,spatial cluster,and the multivarlate stepwise regression analysis method.The main conclusions are as follows:(1) The spatial-temporal pattern analysis of the 360 proposed ecological cities in China shows that,from the aspect of temporal,the space distribution of those proposed ecological cities in China experienced an inverted U-shaped evolutionary process of scatter-cluster-scatter;from the aspect of spatial,the space distribution of those cities showed a strongly geographical differentiation and aggregation;from the aspect of distribution density,the number of cities to carry out eco-city construction has a positive correlation with the degree of economic development.(2) The driving force analysis of the 360 proposed ecological cities in China shows that,city size and city economy are the main driving forces to carry out eco-city construction,while the city′s ecological environment has little impacts on eco-city construction.
