基于GIS的海南热带海洋文化景观空间分布及影响因素分析

Spatial Distribution and Influencing Factors of Hainan Tropical Marine Cultural Landscape Based on GIS

以海南155处热带海洋文化景观为研究对象,运用平均最近邻指数、核密度估计、地理探测器等方法,通过Arc GIS10.8软件,分析海南热带海洋文化景观空间分布特征及发展影响因素。结果表明:(1)热带海洋文化景观在海南省域范围内呈凝聚型空间分布。(2)热带海洋文化景观在市县尺度下较为集中,海南省各市县区域范围内热带海洋文化景观分布不均衡。(3)根据核密度估算结果,将海南热带海洋文化景观概括为以海口市、三亚市为“双核心”,陵水市—琼海市—万宁市—文昌市、儋州市—东方市为“东西两带”,整体空间即呈现“两核两带”分布特征。(4)影响热带海洋文化景观发展的主要原因是等级公路里程密度、旅游总收入、第三产业生产总值、旅游接待人次。提升交通的可达性与便捷性、高质量发展旅游业等可以有效促进热带海洋文化景观快速发展。

Taking 155 tropical Marine cultural landscapes in Hainan as the research object,the ArcGIS10.8 software was used to analyze the spatial distribution characteristics and development influencing factors of tropical Marine cultural landscapes in Hainan by using methods such as average nearest neighbor index,nuclear density estimation and geographic detector.The results show that:(1)The tropical Marine cultural landscape presents a condensed spatial distribution in Hainan province.(2)The tropical Marine cultural landscape is more concentrated at the city-county scale,and the distribution of tropical Marine cultural landscape in Hainan Province is unbalanced.(3)According to the results of nuclear density estimation,the tropical Marine cultural landscape in Hainan is summarized as"double core"with Haikou and Sanya as"double core",Lingshui-Qionghai-Wanning-Wenchang and Danzhou-Dongfang City as"east and west two zones",and the overall space is characterized by"two core and two zones".(4)The main factors affecting the development of tropical Marine cultural landscape are mileage density of graded highways,total tourism income,gross product of tertiary industry and tourist arrivals.Improving the accessibility and convenience of transportation and developing high-quality tourism can effectively promote the rapid development of tropical Marine cultural landscape.
