| 户外骑行活动作为一种休闲活动和零碳交通方式,深受骑行爱好者和通勤人士的喜爱。城市化的快速发展加剧了城市的热岛效应,使得越来越多的人口暴露于城市高温环境中,也必然影响居民开展户外骑行的意愿。基于景观格局指数、线密度分析、双变量空间自相关,分析北京市高温暴露景观格局、刻画骑行路线偏好选择的密度特征、探究高温暴露与户外休闲骑行之间的空间关联,进而为城市的友好骑行建设提供参考依据。结果表明：(1)北京市的地表温度整体上从东城区和西城区等中心城区向外呈递减趋势,城市的建成区面积高于山地和丘陵区域,不同区的温度景观格局不同。(2)受骑行者欢迎路线的空间分布较为集中,这些区域距离市区适中,可以满足骑行者亲近自然的需求。(3)地表温度与骑行路线的选择偏好存在显著的空间负相关,地表温度会显著的影响骑行者的路线选择,并且空间格局呈“离散”状态。高温暴露—低偏好和低温暴露—高偏好的骑行路空间分布最多。 |

| Abstract: |
| Outdoor cycling activities, as a leisure activity and zero carbon mode of transportation, are deeply loved by cycling enthusiasts and commuters. The rapid development of urbanization has intensified the urban heat island effect, exposing more and more people to the high temperature environment in cities, which inevitably affects the willingness of residents to engage in outdoor cycling. Based on landscape pattern index, linear density analysis, and bivariate spatial autocorrelation to analyze the landscape pattern of high temperature exposure in Beijing, characterize the density characteristics of cycling route preferences, explore the spatial correlation between high temperature exposure and outdoor leisure cycling, and provide reference for the construction of friendly cycling in cities. The results show that: (1) The overall surface temperature in Beijing shows a decreasing trend from the central urban areas such as Dongcheng District and Xicheng District outward. The built-up area of the city is larger than that of mountainous and hilly areas, and the temperature landscape pattern varies in different areas. (2) The spatial distribution of popular routes for cyclists is also relatively concentrated, and these areas are moderately located from the city center, which can meet the needs of cyclists to get close to nature. (3) There is a significant spatial negative correlation between surface temperature and the preference for cycling routes. Surface temperature significantly affects the route selection of cyclists, and the spatial pattern is in a "discrete" state. High temperature exposure - low preference and low temperature exposure - high preference have the highest spatial distribution on cycling roads. |
