The Evolution Characteristics of Tourism Resources Endowment in Northeast China and Its Industry Space Refactoring
基于2002、2007、2013年A级景区数据，采用数学和空间分析方法，研究了东北地区旅游资源禀赋的时空演化特征，并提出了旅游产业空间重构思路。
Based on the A-grade attractions data of 2002, 2007, 2013, adopting mathematics and spatial analysis methods such as diversification index, hierarchical structure pyramid, quality of tourism resources, nearest neighbor ratio, point density analysis, unbalanced index and so on, this article discussed the space- time evolution of tourism resources endowment in Northeast China, our findings showed that:1)Just for the mathematical evolution characteristics, the types abundance of tourism resources increased slowly, also the provincial differences were significant; the hierarchy of tourism resources presented thespindle structure, and thespindle structureshowed the evolution characteristics asstructure broken- stable equilibrium- gravity center deviation; the quality of tourism resources generally presented the tendency as rising constantly, and the provincial differentiation of growing rate was apparent. 2)Just for the spatial evolution characteristics, the spatial distribution of tourism resources showed the characteristics as aggregating, the provincial spatial distribution evolution didn't have inevitable impacts to the whole Northeast China; the aggregating hot spots of tourism resources increased continually, and the distributing blind areas were fading, aggregating pattern switching single- core spatial expansion to linked development between administrative regions; the unbalanced index of tourism resources distribution falling constantly, the aggregating tendency was weakening gradually, and the tendency of diffusion was strengthening.On the basis of above researching results, putting forward the refactoring idea of tourism industry space in Northeast China.
