基于可达性技术的长江三角洲旅游区划

区划一直是地理学的核心研究领域,本文以长江三角洲为例,尝试探讨新时期下基于GIS技术的旅游区划分方法。以可达性空间表达技术为基础,通过对旅游点、线要素的相对系统分类,分别对所有A级景区、4A级以上景区和县级城镇、地级及其以上城市可达性进行测算,并分别计算了各自的腹地范围。在此基础上通过对不同时间阀值下腹地范围变化的判断,进行旅游景区腹地范围的空间合并,并对各旅游景区空间分布格局特征进行深入分析,最终将长江三角洲划分为5个旅游大区、27个旅游亚区和85个旅游小区。并进一步从旅游需求和旅游供给的组合角度,对现有旅游小区发展能力进行综合评价,据此构建长江三角洲综合性旅游服务中心等级体系。

Tourism regionalization in the Yangtze River Delta based on accessibility

Regionalization has been one of the core issues in geographical research.Taking the Yangtze River Delta as an example,with accessibility spatial expression technology and systemic classification of point element and line element,we calculated service range of A-grade tourist districts,high-grade(4A and 5A) tourist districts,county-level towns and prefecture-level cities through accessibility.Based on this,we divided the Yangtze River Delta into five regions,27 sub-regions and 85 minor regions through service ranges with different time thresholds and deep analysis of tourist districts distribution pattern.Furthermore,we appraised tourism development potential of each minor region synthetically from an angle of tourism demand and supply elements.Based on development potential,we established the hierarchy of tourism service centers in the Yangtze Delta Delta.
