山东省城乡建设用地转型的时空格局

在深化城乡建设用地转型内涵的基础上,论文构建指标体系并采用主成分分析法、德尔菲法及ArcGIS空间分析等方法对山东省17城市2005—2014年城乡建设用地转型的时空格局进行分析。结果显示：1）城乡建设用地转型是指某一区域一定时期内城乡建设用地利用形态在经济社会发展转型的驱动下所表现出的转变过程,包括结构转型、效率转型和功能转型等三方面。2）山东省城乡建设用地综合转型以及各分项转型平均水平在研究期间均有一定程度的提升,转型水平提升幅度最大的城市为菏泽;其中城乡建设用地功能转型这一维度对综合转型的影响较大。3）2005—2014年,城乡建设用地转型在区域之间的绝对差异和相对差异年际变化较为明显,全省城乡建设用地转型的全局空间自相关性并不显著,区域间转型发展并未出现明显的两极分化现象,但结构转型指数存在较明显的空间差异。4）在未来的城乡建设用地转型发展中,不仅要关注其经济功能,更应注重其对保护和治理环境、改善居民生活质量的推动作用,对区域转型差异进行适度调控和干预。

Spatial-temporal Pattern of Urban-rural Construction Land Transition in Shandong Province

Urban-rural construction land transition (URCLT) refers to the transformation process of urban-rural construction land use driven by the economic and social development in a region during a certain period of time, including urban-rural construction land structural transition, urban-rural construction land efficiency transition and urban-rural construction land function transition. This paper builds index system of URCLT and analyzes the spatio-temporal pattern of URCLT of 17 cities in Shandong Province during 2005-2014 using principal components analysis, Delphi method and spatial analysis method. Principal components analysis and Delphi method are used to obtain the weights of the indices and then the values of URCLT of 17 cities are calculated. Based on these values, spatial-temporal pattern of URCLT in Shandong Province is analyzed. Results show that: 1) The composite index of URCLT and each dimension of the transition have a certain degree of improvement in Shandong Province, in which the urban-rural construction land function transition has the great influence on URCLT. The city with the most URCLT is Heze, which has the change rate of 76.1%. However, the change rate of each dimension during 2005-2014 suggests that Binzhou has the biggest change in structural transition with the change rate of 79.5% and Zibo has the minimum change in structural transition with the change rate of -12.2%; Heze has the maximum change in efficiency transition with the change rate of 146.3%, and Binzhou has the minimum change in efficiency transition with the change rate of 36.3%. The city which has the biggest raise of function transition is Binzhou that the rate is 81.9%, and Dezhou has the minimum change of function transition with the rate of 39.0%. 2) Annual changes of the absolute difference and the relative difference of URCLT between 17cities are obvious; the spatial agglomeration of URCLT in Shandong Province is weak, and there is no obvious polarization of regional URCLT, except that the structural transition of urban-rural construction land has obvious spatial difference. The coefficient of structural transition, efficiency transition and function transition are 0.128, 0.081, and 0.044 in 2005, 0.134, 0.061 and 0.019 in 2009, 0.041, 0.053 and 0.044 in 2014, respectively. The spatial differences of structural transition, efficiency transition and function transition decrease in turn in 2005; the spatial difference of structural transition is the biggest and the spatial difference of function transition is the smallest in 2009; the degree of spatial difference of efficiency transition is the biggest and the spatial difference of structural transition is the smallest in 2014. 3) In the future, we should pay attention to URCLT’s role in protecting and treating environment and improving the life quality of residents as well as URCLT’s economic function. Also, regulation and intervention in the regional difference of URCLT are necessary.
