西部各省区入境游客集聚扩散能力演变对比分析

The evolution and comparison of the concentration and diffusion abilities of inbound tourist flows in western provinces of China

运用入境游客集聚与扩散指数模型、GIS技术,对西部各省区入境游客集散能力进行演变对比分析。结果表明:1)西部各省集聚扩散指数均呈现波动态势,演变过程表现出明显的"峰林结构";入境旅游发展较好的陕西、云南、广西等省区集散指数演变过程较为平缓,其余省份变动则较为剧烈。2)通过集聚指数GIS分析,云南、陕西、四川等3省区处于核心区,集聚入境游客能力最强;新疆自治区与宁夏自治区处于边缘区,集聚入境游客能力最弱。3)通过扩散指数GIS分析,四川、广西、云南等3省区处于核心区,扩散入境游客能力最强;宁夏自治区、青海省等2省区处于边缘区,扩散入境游客能力最弱。

Using models such as spatial concentrated index,diffusion index and GIS technology,the evolution of the concentration and diffusion of inbound tourist flows in western provinces of China was analyzed.The results show that： ①Inbound tourists concentration and diffusion index were fluctuated;the evolution process appeared ＂peak ＂ structure;inbound tourism of Shannxi province and Yunnan province had a better development,the distribution indices changed more quietly,but for other provinces the distribution indices changed more dramatically.② The concentration indices in Yunnan,Shannxi and Sichuan provinces gathered the tourists strongestly.Ningxia autonomous region and Xinjiang autonomous region were in marginal area and gathering of tourists weakest capacity.③ The diffusion indices in Yunnan,Guangxi and Sichuan provinces were in the central area and gathering of tourists strongest.Ningxia autonomous region and Qinghai province were in marginal area and gathering of tourists weakest capacity.
