【摘要】 以2015年海南国际旅游岛55个A级旅游景区为研究对象,基于GIS技术,运用最邻近指数、洛伦茨曲线、Voronoi多边形、地理集中指数、不平衡指数、基尼系数以及空间分析等空间计量地理方法,对其总体分布特征、空间分布格局、空间分布均衡性以及空间通达性进行了定量分析,得出结论如下:海南国际旅游岛A级旅游景区呈现出不均衡的分布特征,其空间分布总体特征表现为线状—核心结构,以海南环岛高速公路东线为主线路,以三亚市、海口市、万宁-琼海市为三个核心区域;海南国际旅游岛A级旅游景区最邻近指数为0.76,表明其空间分布呈现集聚-随机特征,并且其分布均衡性较低;海南国际旅游岛A级旅游景区的平均通达度指数为107.56 km,并且有40个A级旅游景区在距离海南主要公路10 km范围内,其整体通达性较好.更多还原

【Abstract】 Based on an investigation of 55 national A-grade tourist attractions and using GIS and some quantitative analysis methods,such as Nearest Neighbor Index(NNI), Lorenz Curve, Voronoi Polygon, Geographic Concentration Index, Unbalance Index, Gini Coefficient and the spatial structure, equilibrium degree and accessibility of national A-grade tourist attractions in Hainan International Tourism Island were investigated. The result shows that:(1) From spatial structure point of view, the distribution of national A-grade tourist attractions in Hainan International Tourism Island performances a style of agglomeration, while the spatial equilibrium degree tends to be unbalance. The three cluster points were distributed in Sanya, Haikou and Qionghai-Wanning City. The Nearest Neighbor Index of national A-grade tourist attractions is 0.76 and the Lorenz Curve has obvious concave trend in Hainan International Tourism Island.(2) The average accessibility index was 107.56 km, and there are 40 national A-grade tourist attractions distributed in 10 km away from road in Hainan International Tourism Island, which means that the connectivity and accessibility of national A-grade tourist attractions in Hainan International Tourism Island was good.更多还原
