四川省优秀旅游城市空间结构分形研究

A FRACTAL STUDY ON THE SPATIAL STRUCTURE OF EXCELLENT TOURISM CITIES IN SICHUAN PROVINCE

优秀旅游城市是重要的旅游目的地,作为旅游空间的重要节点,具有集散地功能,其空间结构的优化关系到区域旅游空间整合以及整体效应的发挥。运用分形理论,从空间聚集性、关联性和可达性等方面对四川省优秀旅游城市的空间结构定量刻画与分析,结果表明:将分形理论运用于优秀旅游城市空间结构研究是可行的,四川省优秀旅游城市空间结构具有分形的特征;四川省优秀旅游城市围绕中心旅游城市———成都市呈集聚态分布,向心性明显;优秀旅游城市具有集中到某一地理线上的趋势,空间关联性强;交通网络可达性以成都市为中心向周边呈逐渐衰减的空间格局。最后,提出构建"大成都"优秀旅游城市群、"K"形优秀旅游城市空间发展带等优化四川省优秀旅游城市空间结构的建议。

Excellent tourism cities are important tourist destination.As important nodes of a tourism region,they play essential role as tourist centers.The optimization of their spatial structure is related to their spatial integration and the overall effect they have in a region.Based on the fractal theory,this paper quantitatively analyzed the spatial structure of the excellent tourism cities in Sichuan province.The findings indicated that it was feasible to apply the fractal theory to study the spatial structure of excellent tourism cities,and the spatial structure of the excellent tourism cities in Sichuan province had a fractal characteristic.The excellent tourism cities were gathering around the tourism center（Chengdu city）,and the centripetal was apparent.The excellent tourism cities had a trend to gather near a geographical line,with strong space relevance and good transportation network.Finally,based on the spatial structure of the excellent tourism cities in Sichuan province and in order to optimize the spatial structure of the excellent tourism cities,this paper suggests to construct the ＂Great Chengdu＂ excellent tourism city cluster and ＂K＂-shaped development straps of excellent tourism cities.
