【摘要】 以山东省为研究区域,基于信息熵方法探讨2006—2015年城市建设用地结构及规模演变,并采用主成分分析开展了驱动机制分析。研究发现,山东省城市建设用地规模逐年增加,在空间上存在较大差异,东部沿海经济发展较快的城市扩张较为显著。建设用地结构信息熵呈先下降后上升再下降的波动态势,均衡度也呈波动变化,居住用地、工业用地在山东省城市建设用地中处于优势地位,山东省的城市建设用地仍处在开发状态。经济发展、人口变动、交通及产业结构是影响城市建设用地动态变化的主要驱动因子。更多还原

【Abstract】 Based on the information entropy method, the structure and scale of urban construction land in Shandong province from 2006 to 2015 have been analyzed in this paper. By using principal component analysis, driving force mechanism of urban construction land has been carried out. It is showed that the scale of urban construction land in Shandong province has increased year by year, and there are big differences in space. The expansion of the eastern coastal economic cities is more significant. The information entropy of construction land is descending and then fluctuating slightly. The equilibrium degree also fluctuates, and the urban construction land in Shandong province is still in the development state. Economic development, population change, traffic and industrial structure are main driving factors influencing the dynamic change of urban construction land.更多还原
