基于生态位理论,区域旅游城市生态位的测量由旅游资源维、市场维、社会经济维和环境维4大维度31项变量构成。以山东省10地市为例,对区域旅游城市的竞合态势进行了测评,综合生态位排名前3的为青岛、烟台和威海。通过聚类分析,山东旅游城市分为4种类型。基于各城市在区域系统内的地位与作用,进一步指出了各城市的优劣势及发展潜力。 Based on the theory of niche, the measurement of niche in regional tourist cities is made up of 31 variables of 4 dimensions of tourism resources dimension, market dimension and social economic dimension. Taking 10 prefectures and cities in Shandong Province as an example, the competitive landscape of the regional tourist cities was evaluated. The top three integrated ecological places were Qingdao, Yantai and Weihai. Through cluster analysis, Shandong tourist cities are divided into four types. Based on the status and role of cities in the regional system, the advantages and disadvantages and development potentials of cities are further pointed out.
