摘  要：
通过定量分析,综合考虑城市人口、经济、社会、地理空间4个方面的内容,建立衡量区域城市化水平的指标体系;同时运用R型因子分析方法,并借助ArcGIS软件将分析结果与图形数据相结合,对沱江流域5个地市10年的城市化水平进行了综合评价。结果表明:4类影响因子中,社会城市化因子对城市化进程的影响具有普遍性;沱江流域10年间各城市城市化综合指数逐年上升;由于影响城市化水平的主要因子不同,沱江流域不同城市的城市化进程并不一致;随着时间的推移,沱江流域的城市化水平,在空间上呈现由下游城市群向上游城市群转移增大的趋势。由于影响城市化水平的因素的差异,不同地市应根据各自特点,实行差异化的城市化促进政策。

摘  要：
Given full consideration of four aspects of urban population,economy,society and geography,regional urbanization index system was set up to measure the level of city by means of quantitative analysis.At the same time,by the use of R-factor analysis method and with the help of ArcGIS software to combine the results with figures and data,urbanization comprehensive indexes of 5 cities in Tuojiang River watershed from 2000 to 2009 were built.The results showed that the factors of social urbanization were with universal meaning to influence the urbanization in 4 types of factors.Comprehensive indexes of 5 cities in Tuojiang River watershed were rising year by year.Because the main factors to influence the urbanization level were different,and the urbanization process of different cities was not uniform.With the passage of time,comprehensive indexes of upstream cities in Tuojiang river was getting bigger,instead of downstream cities.Due to the difference of main factors to influence the urbanization level,different policies should be applied to promote the urbanization level by respective characteristic of different cities.
