| 摘 要： | 利用标准差指数、变异系数、城市化综合指标、城市的扩展程度等指标对中亚五国城市化发展特征进行研究。结果表明:中亚五国的城市化发展速度和整体水平存在较大差异,城市化发展水平不平衡的特征较明显。城市化水平相对差距由1960年的5.46上升到2009年的12.28,绝对差距由0.15上升到0.3,城市化水平相对差距和绝对差距都表现出总体上升的趋势。而城市化发展阶段也较为落后,目前基本上处于城市化的中期阶段。运用RS与GIS技术,以中亚五国首都城市为代表,研究其城市的扩展强度、扩展速度及城市形状紧凑度,结果显示其城市形状、结构的松散程度较为稳定,说明其城市发展强度不大,速度也是较慢的。

| Abstract: | In recent 50 years,urbanization in five countries of Central Asia was continuously increased.However during this development stage it shows new characteristics.In this paper,based on the standard deviation index,coefficient of variation,urbanization composite index and the expansion of the city level we analyzed the urbanization development characteristics of Central Asia.The results show that urbanization rate and overall level existed obvious differences.The highest level of urbanization composite index was 74.1% which was appeared in Kazakhstan.The second is Turkmenistan,the lowest was Tajikistan,only 45.3%.On the whole,urbanization development level was imbalance.Relative gap of urbanization level of Central Asia's five countries increased from 5.46 in 1960 to 12.28 in 2009,but absolute gap of urbanization level of Central Asia's five countries increased from 0.15 in 1960 to 0.3 in 2009.Relative gap and absolute gap show that rising trend,explaining that in the time scale,the level of urbanization of Central Asia existed obvious differences.From a global perspective,urbanization level of Central Asia was lagging.Capital cities' urban expansion strength index and urban expansion speed existed big gap.Compaction degree range was not too much change,only ±0.5,showing that city shape,structure of the loose degree was relatively stable. |
