城际轨道建设对珠三角地区旅游空间格局的影响

近年来,快速发展的高速铁路、城际轨道等高速交通方式对旅游的影响日益显现。本文以珠三角地区运营和规划城际轨道为例,基于GIS网络分析技术和通达性指标,探讨了城际轨道通车前后对珠三角地区旅游空间格局的影响。结果表明:城轨开通将会产生显著的"时空压缩"效应,旅游景点总通达时间降幅达32.87%,旅游景点平均通达时间减少0.7 h;不同区域通达性水平提升具有差异性,城际轨道站点及其周边地区成为通达性水平提升最大的地区,随着与站点距离逐渐增加,通达性变化程度逐渐降低;城轨开通后各地区通达性水平差异逐渐缩小,并趋于均衡;城轨影响下的旅游景点通达性的影响具有"廊道效应"与"隧道效应"相结合的特征,空间格局由开通前的"中心-外围"态势向面状均衡分布格局转变。城际轨道带来的"时空压缩"效应,在扩大了旅游景点市场范围的同时,由于通行时间成本降低,进一步提高了旅游出行的效率。

Study on the Impact of the Spatial Pattern of Tourist Attractions in the Pearl River Delta with Intercity Rail Construction

Based on GIS spatial analysis techniques,this paper analyzes the impact of tourist attractions spatial pattern of accessibility under construction of the intercity rail.Here comes the main conclusions:in terms of network accessibility,"space ～ time compression" effect generated by intercity rail services makes the total time of tourist attractions reduce from the original 10,032.08 hours to 6734.06 hours,down to the 32.87％;And the number of 1 hour circle of the 98 cities reaches 48,and up to 64 of 2 hours circle at the same time,respectively 232％ and 39％ increasing;The travel time of tourist attractions reduces of 0.7 hour in average,and substantially from the center consists of Guangzhou,Foshan,Dongguan and Shenzhen to the east and west wings increments.In terms of Huizhou,Zhaoqing,Jiangmen and other marginal areas,the construction of urban rail benefits more visible,further enhance the attractiveness of tourist attractions in the edge region of the Pearl River Delta,greatly opened up its market.Therefore,intercity rail brings "space ～ time compression" effect,expanding the market range of tourist attractions from the supply side,however,from the demand side,because of reduce of travel time,it further increases the likelihood of a short tourism activities.
