中文摘要：

基于对城市化概念的认识，通过测算中国各城市的人口、经济和空间城市化率及其增长速度，运用Arcgis9．3支持下的热点分析方法，考察2000-2008年中国城市单元城市化水平增长的空间分布特征，揭示了中国城市化的空间模式，认为2000年以来中国的城市化发展热点仍然在东部沿海，主要围绕环渤海和珠三角两大城市化热点城市群，向东北、西北、西南等冷点区中心辐射、梯度推移；城市化的发展速度与地区经济发展水平有一定的空间相关性，但与经济增长格局有较大偏差，现有经济发展水平对于城市化的拉动作用相对经济增长更为明显；城市化空间格局的形成受自然、历史、政策、经济、人口等诸多因素的影响，其作用机制主要包含政府主导的“自上而下”和市场主导的“自下而上”两种道路，未来政府作用将逐渐弱化，推力的主动力地位将进一步强化。

英文摘要：

Based on understanding of the concept of urbanization, the article estimated the population, economic and spatial urbanization levels and their growth rates of Chinese cities, and used the Hot Spot Analysis supported by Arcgis 9.3 to study the spatial distribution of the growth levels of urbanization of Chinese cities from 2000 to 2008 ,then revealed spatial model of urbanization in China. The conclusions include： the hot spots of development of urbanization in China since 2000 are still in the eastern coastal areas, mainly around the two big urban agglomerations which are the Bohai Rim and Pearl River Delta, and radiate gradually to the northeast areas, northwest areas and southwest areas which are cold spots. There is certain spatial correlation between the speeds of urbanization development and the level of urban economic development, but economic there is greater deviation between the speeds of urbanization development and the speed of urban growth, which means that the existing level of economic development has more pulling effects on the urbanization development than the economic growth does. The formation of spatial pattern of urbaniza- tion is under the influence of factors such as nature, history, policy, economy, population, and its mechanism mainly consists of government-led ＂top-down＂ and market-oriented ＂bottom-up＂ two roads. In the future the role of government will gradually weaken and the status of active force of the thrust will be further strengthened.
