郑州市旅游资源空间格局特征及便利度评价

Spatial pattern characteristics and convenience evaluation of tourism resources in Zhengzhou

以国家中心城市郑州的旅游类兴趣点数据为基础,运用核密度分析、标准差椭圆分析、空间相关性分析等GIS空间分析方法,对郑州市旅游资源空间格局特征及便利度进行分析,为郑州市旅游空间布局规划决策提供科学依据。研究结果表明:(1)郑州市旅游资源空间分布不均衡,整体上表现为“北多南少、北密南疏”的格局,呈现出面状集聚和点状分布并存的局面,市辖区的旅游资源远多于其他区县;(2)郑州市旅游资源相对较分散,各类旅游资源主要沿“东南-西北”“东北-西南”的方向分布,且存在一定的向心性;(3)餐饮、酒店、交通等服务设施与不同城市旅游资源类型的空间匹配度不同,其中交通设施与旅游资源的空间匹配度最高,旅游资源倾向于分布在交通发达、食宿方便的区域;(4)郑州市旅游资源便利度在空间上表现为“中间高,四周低,城区连片,郊区分散”的整体格局。

Based on the POI data of tourist resources in Zhengzhou,a national central city,the characteristics and convenience of tourism resources spatial pattern in Zhengzhou City was analyzed by using GIS spatial analysis methods such as kernel density analysis,standard deviation ellipse analysis and spatial correlation analysis,so as to provide scientific basis for the planning and decision-making of tourism spatial layout of Zhengzhou city.The results show that:(1)The spatial distribution of tourism resources in Zhengzhou is unbalanced,which show a pattern of"more in the north and less in the south,dense in the north and sparse in the south"as a whole,showing the coexistence of concentrated agglomeration and point distribution.The tourism resources in the municipal districts are far more than those in other districts and counties.(2)Zhengzhou’s tourism resources are relatively scattered,and various tourist resources are mainly distributed along the"southeast-northwest"and"north-southwest"directions,and there is a certain degree of centrality.(3)The service facilities such as catering,hotel and transportation have different spatial matching degree with different types of urban tourism resources.Among them,the spatial matching degree of transportation facilities and tourism resources are the highest,and tourism resources tend to be distributed in areas with developed transportation and convenient accommodation.(4)The convenience of tourism space in Zhengzhou is represented by the pattern of"intermediate high,ambient low,contiguous in the urban area,scattered in the suburbs".
