摘　　要：要建设宜游湾区,就需要进一步评估珠江口的跨海通达性,以更好地解决湾区东西两岸的联结问题。利用成本加权栅格法,从等时圈面积变化、日常可达性、加权平均旅行时间和旅游经济联系强度4个方面,以港珠澳大桥和深中通道为例(以下简称“一桥一通道”),分析新建跨海通道对粤港澳大湾区旅游景点可达性的影响。研究得出:1)在一定空间范围内,旅游景点可达性提升存在边际递减效应,且提升效应以跨海通道的起止点为中心距离衰减,大湾区可达性提升的主要矛盾由绝对值提升转变为控制区域差距扩大和结构失衡问题;2)一桥一通道对旅游可达性的影响主要集中在珠江口东西两岸,中部地区效果不明显,其中港珠澳大桥主要提升大湾区2 h交通圈面积,深中通道主要提升1 h交通圈面积;3)从景点可达性看,一桥一通道大幅增加了珠江东西两岸1 h可达景点数量,使大湾区环珠江口地区能够形成较为紧密的旅游圈,整体景点可达性从1.20 h压缩至1.12 h,肇庆、江门、惠州是短板;4)以旅游经济联系强度衡量大湾区的旅游经济格局变化,发现一桥一通道并未改变广佛、深港、珠澳三核心组团格局,而且进一步巩固了三者的集聚态势。To establish a tourism-friendly bay area,it is essential to assess the cross-sea accessibility of the Pearl River Estuary,thereby effectively addressing the connectivity issues between the eastern and western shores of the bay area.Utilizing the cost-weighted grid method,this study examines the impact of newly built cross-sea channels on the accessibility of tourist attractions in the Greater Bay Area(GBA)from four aspects:changes in isochrone area,daily accessibility,weighted average travel time,and tourism economic linkage intensity.Taking the Hong Kong-Zhuhai-Macao Bridge and the Shenzhen-Zhongshan Channel(hereinafter referred to as“B&C”)as examples,the study analyzes their influence.The conclusions are as follows:1)Within a certain spatial scope,there is a marginal diminishing effect on the improvement of tourist attraction accessibility,and the enhancement effect declines with distance from the starting and ending points of the cross-sea tunnels.The main contradiction in improving GBA accessibility has shifted from absolute value enhancement to controlling the expansion of regional disparities and structural imbalances.2)The impact of B&C on tourism accessibility is concentrated mainly on the eastern and western shores of the Pearl River Estuary,with insignificant effects on the central region.Specifically,the HKZMB primarily enhances the area of the 2-hour traffic circle in the GBA,while the Shenzhen-Zhongshan Channel mainly expands the 1-hour traffic circle.3)In terms of attraction accessibility,B&C significantly increase the number of attractions reachable within 1 hour on both shores of the Pearl River,enabling the areas around the Pearl River Estuary in the GBA to form a relatively close tourism circle.The overall attraction accessibility is compressed from 1.20 hours to 1.12 hours,with Zhaoqing,Jiangmen,and Huizhou representing weaknesses.4)Measuring the changes in the tourism economic landscape of the GBA based on tourism economic linkage intensity reveals that B&C have not altered the three core
