南昌市旅游景点空间分布特征研究

Study on the Spatial Distribution Characteristics of Tourist Attractions in Nanchang

分析景点的空间集聚性、空间均衡性、交通可达性是保证景点空间合理布局的一项重要前期工作。基于POI(兴趣点),数据通过GIS空间分析法、基尼系数以及等时圈构建等分析南昌市旅游景点空间分布特征。结果表明:(1)南昌市的旅游景点整体空间分布模式为集聚型,分布形态为多中心式发展。此外,不同类别旅游景点的空间集聚特征上存在较大差异。(2)从基尼系数计算结果来看,南昌市旅游景点基尼系数值接近1,说明景点资源在区域分布极不均衡。(3)根据等时圈与缓冲区分析结果,综合全域范围内的旅游景点可以发现公交车出行的整体通达度高于地铁,但不同区域不同类别景点交通可达性有所不同。

Analyzing the spatial agglomeration,spatial balance and accessibility of fourist attractions plays an important role in preparing for the preliminary work,which is conducive to rational spatial layout of tourism.Based on Pol(point of interes)data,this paper analyzes the spatial distribution characteristics of tourist attractions in Nanchang by GIS spatial analysis method,Gini coefficient and isochrones.The results show that:(1)The overall spatial distribution mode of tourist attractions in Nanchang city is characterized by agglomeration characteristics,and the distribution form presents polycentric development trend.In addition,there are differences in the spatial agglomeration characteristics of different types of tourist attractions.(2)Judging from the calculation results of the Gini coefficient,the value of tourist attractions is close to 1 in Nanchang,indicating that the distribution of tourist attractions resources is extremely uneven in the region.(3)Based on the results of the isochrones and buffer research,and through analyzing the accessibility of public transportation in comprehensive tourist attractions in the whole region,it is found that the accessibility of bus travel is higher than that of the subway,but the traffic accessibility of alltypes of attractions in every regions is different.
