根据1995—2008年《辽宁省统计年鉴》及土地利用数据,以人口城市化率反映城市化水平,基于信息熵和均衡度原理,分析了辽宁省城市化过程中土地利用结构的动态变化特征,探讨了土地利用结构信息熵和均衡度动态变化的驱动机制。结果表明,伴随着城市化的不断加快,1995—2008年辽宁省土地利用信息熵、均衡度呈现波动状态,各土地利用类型的面积占土地总面积的比例逐渐趋于均衡。但从总体趋势看,土地利用结构的均质性较差,人口因素、经济因素是影响土地利用结构信息熵和均衡度时空变化的主要驱动因子。
According to"Statistical Yearbook of Liaoning Province"in 1995—2008 and land-use data,used population urbanization rate to reflect the level of urbanization,based on information entropy and principle of equilibrium degree and analyzed the characteristics of land-use in urbanization proceeding of Liaoning Province.The driving forces of information entropy and equilibrium degree were discussed further.The results showed that with the urbanization accelerating,from 1995 to 2008,Liaoning Province of land-use information entropy,equilibrium degree fluctuated,and the proportion of each types of land-use in the total land area became more and more balanced,but in general,the uniform of land-use structure was poor.Population factor,economic factor were the driving forces affecting the temporal changes of information entropy and equilibrium degree values of land-use structure in Liaoning Province.
