基于点要轴理论的环渤海地区旅游空间结构研究

环渤海地区共157座城市，约占全国城市的四分之一，陆地面积112万平方公里，约占全国国土面积13.31%，总人口2.6亿，占全国总人口22.2%。全区交通便利，人均收入水平高，旅游资源丰富，类型多样，是集山、泉、林、岛、江、河、湖、海为一体的自然景观和古代文明与现代艺术相结合的人文景观构成的旅游大区。点轴系统理论对旅游区域开发研究具有十分重要的指导意义，以环渤海地区为研究对象，使用旅游区位熵和城市流，从理论上分析并归纳了环渤海地区概况，并据此确定了环渤海地区四个等级的重要发展节点，二个等级的旅游发展轴线以及三大旅游区，构建了环渤海地区“点—线—面”的区域旅游空间结构体系，合理的空间结构可以促进全区发展，带动环渤海地区各市旅游业繁荣。

Research on the tourism space structure of the Bohai sea ring area based on the pole-axis theory

Bohai Rim is a tourism area composing of natural landscape, inte-grating hills, springs, forests, rivers and lakes, and artificial landscape, combining ancient civilizations with modern art. Pole-axis theory has impor-tant guiding significance for the development of tourist regions. Using Loca-tion Quotient and City Flow, the profile of the Bohai sea ring area is ana-lyzed theoretically. Based on this, its important development nodes of four ranks, tourism development axis of two ranks and three tourist regions are in-dentified to construct the point-line-spatial regional tourism space structure to construct reasonable space structure to promote the development of the re-gion to drive the development of tourism industry of its own cities. Through reasonable space structure, tourism areas, according to their local condi-tions, bring their specialties into full play with a clear direction of devel-opment. Development axis has been identified, which has made great contribu-tions to strengthening cooperation among areas, expanding their influence, achieving group development. Reasonable tourism space structure promotes the flow of tourists, information, capital and so on, forming a new the develop-ment pattern of the complementary of the tourism resources and the sharing of the tourist source. What’s more, the combination of marine and land resources and the integration of traditional culture and modern style push forward the development of regional tourism.
