摘　　要：利用主成分分析法,选取表征西藏自治区城镇化的人口、产业、用地、社会和自然环境等方面的变量,提取了西藏自治区城镇化特征的主成分,并通过聚类分析划分了西藏自治区城镇化类型.结论如下:(1)西藏自治区城镇化内容可归纳为7大主因子:"援藏因子"、"消费因子"、"农业因子"、"自然因子"、"城建因子"、"二三产业因子"和"教育因子",体现了西藏自治区发展的特点;(2)2015年西藏自治区城镇化可划分为"中心地服务型"、"农牧业生产型"、"二三产业发展型"、"援助依赖型"、"帮扶援建型"、"自然环境限制型"和"自然环境依托型"等7种类型,不同类型的城镇化特征明显;(3)西藏自治区城镇化模式不同于全国大部分地区,城镇化建设不能照搬其他地区经验.Using the principal component analysis method,the variables characterising the urbanization of Tibet Autonomous Region selected from population,industry,land,social aspects,and natural environment are standardized to extract the principal components representing the characteristics of the urbanization of the Tibet Autonomous Region. The urbanization of the Tibet Autonomous Region is divided into different patterns by clustering analysis.Conclusions are drawn as follows:( 1) Factors of Tibet Autonomous Region's urbanization are summarized as 7 main factors,namely "outside aiding factor","consumption factor","agricultural factor","natural factor","construction factor","industrial factor"and "education factor",and the main factor that embodies the characteristics of Tibet Autonomous Region.( 2) The urbanization pattern of Tibet Autonomous Region in 2015 can be divided into"service centered type","agricultural environment produced type","industrial development type","aiding dependent type","aiding type","natural environment restricted type"and"natural environment supporting type". The characteristics of different types of urbanization are obvious.( 3) The pattern of urbanization of Tibet Autonomous Region is different from that in most areas of China. The experience of urbanization construction of other areas cannot be copied to Tibet Autonomous Region.
