摘　　要：土地利用空间结构作为土地利用规划学科的核心问题,其多尺度研究对土地利用空间规划有重要参考价值.论文借助多维计量模型和GIS空间分析方法,从多维度、多尺度视角研究江淮城市群土地利用结构的空间分异规律,结果表明:(1)市域尺度上,江淮城市群市域土地利用多样化空间格局整体呈现中西部偏高,南北两侧偏低的递减格局,整体优势度指数偏低,但其空间格局呈现南北两侧高、中间低的异质特征,均匀度处于中等水平,且各地市空间分布格局与其优势度呈显著的负相关分布特征.(2)县域尺度上,江淮城市群土地利用多样化格局整体上呈现沿江地区高、沿淮地区低、江淮之间居中的空间分布特征,集中化指数空间格局由西北部向东南部呈现递阶下降的分布特征.与市域尺度相比,整体优势度较为明显,且各县区呈现以沿江低优势度指数地区为轴线,以霍邱县、寿县和石台、铜官山区等高优势度指数地区为两翼的非对称性"凹"字型空间分异特征.Multi-scale analysis on land use spatial structure is the core issue of the land use plan. This paper studied the spatial variation of land use structure of Jianghuai urban agglomeration at multi-scale, using the methods of quantitative geography madel and GIS technology. The results shows that：（1）On urban scale, there is a significant spatial distribution in the land use structure among the study area, showing the following regular patterns： the＇structural diversity and composed types o{ land-use decrease by degrees from the middle area to the north and south sides, but the centrality and dominance index of land-use spatial pattern is on the contrary, and the evenness is high in center than at edge, and the dominance is significantly negatively correlated;and land-use spatial variation of location quotient has obvious advantage. （2）In county level, the distribution of different land-use types is spatially unbalanced, the structural diversity of land-use decrease by degrees from the south area to the north area in JianKhu.ai Urban Agglomeration; the centrality of land-use structure shows a gradual decline from the northwest to the southeast; however, being relative to the urban scale, the dominance is relatively high, and each county district has takes along the low dominance index in the region as the axis, the other high dominance index as the two wings, showing the different characteristics of the concave shape space in the non symmetry.
