Change of Regional Urban Land Intensive Use and Analyses on Influential Factor s
1997~2005 年区域城市土地集约度变化 与影响因子分析

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.
