Abstract: The Bohai Rim is a key development zone in China, consisting of 157 cities, a quarter of its cities, covering an area of 1.12 million square kilometers, 13.31% of its territory and having a population of 0.26 billion, 22.2% of its population. With convenient traffic, high income per capita, rich and diverse tourism resources, Bohai Rim a?tourism area?composing of natural landscape, integrating hills, springs, forests, rivers and lakes, and artificial landscape, combining ancient civilizations with modern art. Pole-axis theory has important guiding significance for the development of tourist regions.Using Location Quotient,City Flow and index of central functions, the profile of Bohai Rim is analyzed theoretically. Based on this, its important development nodes of four ranks, tourism development axis of three ranks and four tourist regions are indentified to construct the point-line-spatial regional tourism space structure to construct reasonable space structure to promote the development of the region to?drive the development of tourism industry of its own cities.
