基于GIS的旅游交通巨变下客源空间结构演化分析——以惠州龙门县为例

Analysis of Spatial Structure Evolution of Tourist Source under Great Traffic Change in Fast Developing Regions Based on GIS:A Case Study of Longmen County

基于GIS技术,结合旅游需求引力模型,以惠州市龙门县为例,选取3个时间段,对旅游交通变化驱动下的旅游客源空间结构演化进行分析。结果显示,龙门县旅游交通从无高速公路连接、向有相关高速公路连接到高速公路过境变化,客源市场空间结构对应表现为经济要素为第一指向性的跳跃式分布、向交通要素为第一指向性转变的连续分布到基本以交通驱动为主的连续梯度分布。认为旅游交通变化是客源市场演化的重要驱动要素,交通巨大改善会导致客源市场空间结构扩展,且扩展的方向基本与交通变化路径一致。

Taking Longmen County of Huizhou City, a fast developing region in tourism, as an example, the paper uses gravity model of tourism demand with GIS technology to analyze the spatial structure evolution of tourist source in three different periods, namely, 1999-2003, 2004-2008 and 2009-2013. It is believed that tourism traffic change is an importance driving force for the evolution of the spatial structure of tourist source. Improvement of tourism traffic can lead to expansion of tourist source, and the expansion direction is basically in accord with the traffic change way. The evolution of spatial structure of tuorist source can be summarized into three patterns. The first is discontinuous jumping distribution in 1999-2003 when there was no expressway in the county and economic factors were the first driving force for the evolution. The second is continuous distribution in 2004-2008 when there were some highways to connect the nearest expressway outside the county and traffic factor began to be the first driving force. The third is continuous gradient-based distribution in 2009-2013 when expressway will run through the county, and the traffic factor certainly will be the first driving force.
