长吉图旅游生态位宽度和重叠度实证分析

Empirical Analysis of Ecological Niche Breadth and Niche Overlap in Chang-Ji-Tu

区域旅游协同共生是实现全域旅游的必经之路,将区域内的旅游资源、产品和市场进行重新配置,有助于实现旅游业的转型升级。运用生态位理论构建旅游生态位评价体系,对长吉图区域内9个城市的旅游生态位宽度和旅游生态位重叠度进行测算,并使用SPSS22.0软件对测算结果进行分析。结果表明:(1)区域内城市的旅游生态位差异较大,长春、吉林、延吉综合旅游生态位居前三位,在竞争中处于优势地位;(2)根据系统聚类谱系图,将区域内城市分为核心城市、次核心城市、增长极城市、边缘城市四个等级,针对不同等级的城市提出对应的旅游发展策略;(3)区域内城市的竞争压力较大,各维度旅游生态位重叠度均超过0.7。

Collaborative symbiosis of regional tourism was a necessary way to fulfill the all-for-one tourism,therefore the relocation of regional resource,products and markets was beneficial for the transformation and upgrading of tourism.Based on the ecological niche theory,an evaluation system was constructed to calculate the niche breadth and the niche overlap of nine major cities in Chang-Ji-Tu and SPSS22.0 was applied to analyze the data.The conclusions were as follows: ①There was a great difference of tourism niche among the nine regional cities,in addition,Changchun,Jilin and Yanji which were the top three cities in the rank of comprehensive niche were in the dominative positions in the competition.②According to the clustering pedigree chart,cities in the region were classified into four levels,which included core city,sub-core city,development of growth pole city and edge city,and development strategies targeting each level were put forward.③The pressure of competition was relatively large and the niche overlap of each dimension exceeded 0.7.
