基于腾讯迁徙大数据的长三角城市群春运人口流动时空特征

开展城市群人口流动研究对促进区域人口有序流动和城市群协同发展具有重要的理论和实践指导意义。本文基于腾讯迁徙大数据，运用GIS空间统计和K-shell分解等方法，从人口流动总量、位序、时序和网络层级等方面，对我国长三角城市群2018年春运期间的人口流动特征进行系统研究。结果表明：①长三角城市群春运期间大规模的“返乡流”和“返城流”呈现明显的对称性，并分别于除夕和第一个工作日达到最高峰。②经济发展水平相对较高的上海、苏州、杭州等为劳动力输入型城市，而经济发展水平相对较低的盐城、安庆和滁州等为劳动力输出型城市。③长三角城市群内部人口流动网络具有明显的层级特征，其中上海和杭州是人口辐射核心城市，上海-合肥、上海-南京、上海-杭州等是人口流动的主体路径；空间上东部-西部横向人口流动最为频繁，大体呈现“Z”字形。     

LONE WOLVES? ISOLATION AND SOLITUDE WITHIN THE FRONTIER TRAVEL EXPERIENCE

The frontier traveller, venturing out into the peripheral parts of our world such as the poles, the peaks of mountains or the great deserts, must deal with the remoteness and riskiness of the setting. The traveller is mentally apart from friends and family, and immediate rescue may be difficult, if not impossible. This article explores the attraction of remoteness, isolation and solitude for the frontier traveller, using qualitative interview and biographical data collected in a study of frontier travel experiences. Some participants referred to intense, spiritual experiences at the frontier, with the remoteness and silence of their journeys facilitating reflection, both internal and external. Isolation and solitude appear to engender a sense of freedom and escape from the cares of everyday life in the frontier traveller, while the study also highlights the attraction of self‐sufficiency in remote settings, particularly during the solo frontier travel experience, where the individual is forced to make decisions and manage situations, without recourse to another's advice, skills or experience. The resultant heightened challenge and risk was perceived as a form of authenticity by some participants. The links between isolation and opportunities for self‐actualization are also noted in this article. The implications of these findings for marketing tourism experiences are examined, given the potential for the peripheries to become more accessible to tourists in the future, as well as the role played by culture and privilege in these types of adventurous experiences in far‐flung locations.
