- Abstract:
-
Based on the connotation of urban intensive land utilization, an evaluation index system was constructed from the intensity of land investment, the intensity of land utilization, the benefit of land output and the quality and sustainable development of the ecological environment. City group around Chang-Zhu-Tan was taken as an example, the intensive land utilization evaluation was carried out in the built-up area land in 2001, 2005, 2008 and 2011 in 8 prefecture-level cities by adopting the PCA method and entropy method. Then the evaluation results were divided into four categories of land intensive utilization, and further research on the spatial-temporal evolution of land intensive utilization had been conducted. The results indicated: (1) with respect to the temporal evolution characteristics, overall, the intensive land utilization of the whole area embraces a rising trend, Changsha is always in the level of intensive utilization, outperforming other cities by certain degree, Zhuzhou and Xiangtan have basically achieved the relatively intensive utilization level, and those level of Yueyang, Changde and Loudi keeps rising, while Hengyang and Yiyang fluctuate at a low level in this regard; (2) with regard to spatial evolution characteristics, the intensive land utilization level in the whole area presents obvious spatial difference. The intensive land utilization level of the eastern region is higher than that in the western region, and it decreases to the north and south in terms of taking Changsha as the center.
