摘要：

城市土地集约利用研究具有非常重要的意义。本文以不同区域内的14 个省会城市为研究对象，从城市承 载力和城市协调度两个方面挑选了20 个指标，采用主成分分析的方法计算得出14 个城市1997—2005 年间的城 市土地集约利用值，得出了重要主成分所含的指标及其在研究期间内的变化与差异；然后从区域城市土地集约利 用的角度出发，分析了不同区域内城市土地集约度变化的一致性和变化趋势；以变化为基础，将影响因子分为自然 导向型、投入导向型、产出导向型和城市容貌导向型四个不同类型，分析了这些类型的影响因子在研究期间内的变 化，同时结合城市土地集约利用度分析了这些类型影响因子的作用。本文一方面全面掌握了区域城市土地集约利 用变化的趋势；另一方面为城市土地集约利用挖潜提供了参考。

Abstract:

the research of regional urban land intensive use is important for urban construction and development. In this paper, there are 14 capital cities chosen as the objects, which are chosen according to the different regions. In the same time, there are 20 indicators selected from urban carrying and urban harmonizing. Then the method of principle component analysis is taken to get the values of different urban land intensive use from 1997 to 2005, from the values, the results can be concluded that the effect of urban carrying indicators is more obvious than that of urban harmonizing indictors. In the process of urban land intensive use change, the sample cities are divided into 6 small regions and 3 big regions, in the small regions, the survey indicators of difference and stdev are used to reflect the consistence of urban land intensive change, and Haerbin City and Shenyang City, Chengdou City and Kunming City take on the high consistence. In the big regions, the intensive degree of eastern cities is higher than that of middle cities and western cities. At last, the influential factors of change are summarized from the natural direction, input direction, output direction and urban feature direction, and analyses on the trend of influential factors change in the research time, meanwhile, the correction between these influential factors and urban land intensive use. This paper on one hand make the regional urban land intensive use change clear, on the other hand, provide references for the undermining of regional urban land intensive use.
