摘要:

运用GIS空间分析方法对合肥市2007-2011年经营性用地价格时空演变的特征进行分析。结果表明合肥市地价时空演变具有圈层式扩展、轴向梯度延伸、空间变异和空间分异四大特征。结合遥感影像图对合肥市历版城市总体规划和2006版城市总体规划作用下空间演进的特征进行分析。结果表明2007年城市地价的空间结构及特征是1956-2001年四版城市总体规划及实施形成的城市空间结构的重要表征,2006年编制的城市总体规划及实施是2007-2011年城市地价时空演变的重要影响因素。城市中心区的拓展、位移和跳跃导致地价圈层式扩展和局部空间变异;城市主导发展方向导致地价峰值区集聚轴的形成;城市空间结构的演变导致地价空间分异;新兴空间生产布局导致城市地价的空间分异和空间变异;土地出让时空密度导致城市地价的空间变异。因此,城市中心区范围的扩展和位移、主导发展方向的改变、空间结构与形态的演变、城市新兴空间的生产以及城市总体规划的实施空间选择是影响地价时空演变的重要因素。而地价时空演变的空间特征是城市空间发展策略调整的重要依据。因此,加强城市新兴空间的生产、置换城市主导发展方向上的工业区、结合游憩中心区打造城市新兴功能组团、围绕城市空间转型和地价时空演变建设城市重大基础设施和公共服务设施、优化城市多中心多组团的空间结构、分片区逐步开发是城市空间调整的响应策略。

Abstract:

The characteristics of the profit-oriented land price temporal-spatial evolution in Hefei from 2007 to 2011 are analyzed using the GIS spatial analysis method. Results show that the temporal-spatial evolution of land price in Hefei is characterized by circular-layered expansion, axial-gradient-form extension, spatial variation and spatial differentiation. Moreover, aided by remote sensing images, this paper analyzes the characteristics of spatial evolutions resulting from previous versions of the overall urban plan for Hefei and the 2006 version of the urban master planning for Hefei. According to the analysis results, the spatial structure and characteristics of the urban land price in 2007 are the important manifestation of the urban spatial structure brought about by the four versions, made up between 1956 and 2001, of the overall urban plan and their implementations, while the 2006 urban master planning and its implementation are the important factors influencing the spatial-temporal evolution of urban land price between 2007 and 2011. The expansion, displacement and jump of urban center lead to the circular-layered expansion and local spatial variation of land price; the leading direction of urban development results in the formation of concentration axis in the peak land-price area; the evolution of urban spatial structure results in the spatial differentiation of land price; the layout of the generation of newly emerged space results in the spatial differentiation and spatial variation of urban land price; and the spatial-temporal density of land transfers results in the spatial variation of urban land price. Therefore, the spatial-temporal evolution of land price is significantly influenced by the expansion and displacement of urban center, the alteration of the leading development direction, the evolution of spatial structure and form, the generation of new urban space, and the space selection in the implementation of the urban master planning. And the spatial characteristics of the temporal-spatial evolution of land price are an important basis for the adjustment of the strategies for urban space development. Therefore, the response strategies in the adjustment of urban space are: to strengthen the generation of new urban space, to displace the industrial zones in the leading direction of urban development, to establish new functional groups by including recreation center, to construct major infrastructure and public service facilities based on the urban-space transformation and the land price temporal-spatial evolution, to optimize the urban space structure featuring multiple centers and multiple groups, and to achieve gradual development of each sub-area.
