西部边疆旅游城市功能区空间集聚模式——以云南省丽江市为例

Spatial Agglomeration Mode of Urban Functional Areas in Western Frontier Tourist City:A Case Study of Lijiang City,Yunnan Province

以丽江市古城区与玉龙纳西族自治县为研究区域,基于丽江市POI数据,采用土地利用混合度熵值、行业地区集中度指数作为研究指标,用ArcGIS,MATLAB等提取旅游城市的空间格局及行业分布特征。结果表明:丽江市形成“以人文景点为导向”的城市空间格局,景点周围区域以不同比例分布着与旅游产业关联性显著的商业、公共服务;与旅游产业相关的住宿、餐饮集聚程度最高,行业集中度指数分别为0.97(住宿)、0.96(餐饮);区域内住宿、餐饮服务对景点的依附程度高,并且高度集聚于丽江古城周围区域,区域内98.7%的住宿服务、97.5%的餐饮服务均分布在以丽江古城所在地为中心、半径为10 km的区域内。

By selecting Lijiang ancient town and Yulong Naxi autonomous county as the study area,this paper extracts the entropy of land use mix degree and industry concentration index as the research indexes based on POI data of Lijiang City.ArcGIS,MATLAB and other tools were used to refine spatial pattern and industry distribution characteristics of tourist cities.The results show that Lijiang City forms a“cultural attractions oriented”urban spatial pattern,the areas around the scenic spots are distributed with different proportions of businesses and public services that are significantly related to the tourism industry;The concentration degree of accommodation and catering related to the tourism industry is the highest.The concentration ratio is 0.97(accommodation)and 0.96(catering);The accommodation and catering services in the study area have a high degree of attachment to scenic spots and are highly concentrated in the area around the ancient city of Lijiang.98.7%of the accommodation services and 97.5%of the catering services are distributed in a circle with the location of the ancient city of Lijiang as the center and a radius of 10 km.
