基于分形维数的重庆都市圈景区空间结构优化研究

Research on Scenic Spatial Structure Optimization in Chongqing Urban Areas Based on Fractal Dimension

运用分形维数和GIS空间分析工具,采用测算重庆都市圈旅游景区空间结构的集聚维数、网格维数和关联维数的方法,对其自组织演化空间特征进行研究。研究表明重庆都市圈旅游景区空间结构是分形的,旅游景区从中心向外围由密到疏,具有向河流、交通、山脉集中的趋势,都市核心区空间关联性较都市拓展区空间关联性弱,并提出"疏通文化景区脉络,打造环城观景走廊",实行"藤结瓜"型旅游景区集聚发展格局的优化策略。

In this paper, fraetal dimension and GIS spatial analysis tools are used to measure the Aggregation dimension, Grid dimension and Correlation dimension of urban tourist scenic spatial structure of Chongqing City and analyze its characteristics in the evolution of self-organizing. The research indicates that urban tourist scenic spatial structure of Chongqing is fraetal, and that the density of tourist attractions decreases from the center to the edge, with a trend of converging toward the river, traffic and mountains. The spatial correlation is weaker in developed urban areas than in the developing urban areas. Therefore, the paper proposes the optimization strategies, including ＂clearing the travel channel of cultural attractions and building a scenic corridor around the city ＂, and taking ＂Melon-on-the-vine＂ as the main spatial structure of Chongqing metropolitan.
