【目的】研究乌鲁木齐市生态系统服务水平和游客活动足迹的时空格局,探索二者之间的时空响应关系,分析不同类型响应关系形成机制,为区域生态安全维护及旅游发展提供科学依据。【方法】利用乌鲁木齐市2010、2015、2020年的土地利用、土壤及降水数据,运用InVEST模型评估其生态系统固碳能力、产水能力以及生境质量,并综合测算其生态系统服务水平;同时,利用相同时间段内乌鲁木齐市兴趣点(POI)数据,分析游客活动足迹空间范围。在此基础上,解析二者的时空全局和局部响应关系。【结果】①乌鲁木齐市生态系统服务水平在建成区和北部沙漠地区存在低值聚集,而四周森林、草地和高山冰雪地区存在高值聚集;②以POI表征的游客活动足迹则显著聚集于建成区范围内,并随时间推移不断向四周扩散;③乌鲁木齐市生态系统服务水平与游客活动足迹整体存在较为显著的负向响应关系,局部时空响应关系则主要表现为“高生态系统服务-低游客活动”的负向响应关系,以及一定范围内的“低-低”正向响应关系。【结论】乌鲁木齐市应该利用各类资源进一步开发沙漠游、森林徒步、草原游憩以及高山冰雪游,促进生态系统服务水平和旅游业的协调发展;进一步完善城市旅游接待设施,提升城市旅游服务质量;优化市内公共交通、汽车租赁等形式,提高生态空间交通可达性,引导游客活动足迹有序外延,促进生态系统服务和旅游业协调发展。

【Objective】This study investigates the spatiotemporal patterns of ecosystem services and tourist activity footprints in Urumqi, elucidates their coupling mechanisms, and proposes strategies for their coordinated development. 【Method】Based on land use, soil, and meteorological data from 2010, 2015, and 2020, the InVEST model was employed to assess carbon sequestration, water yield, and habitat quality, thereby quantifying the integrated ecosystem service level. Concurrently, point of interest (POI) data from the same periods were utilized to delineate the spatial distribution and evolution of tourist activity footprints. The global and local spatiotemporal response relationships between these two elements were subsequently analyzed. 【Result】(1) Ecosystem service levels exhibited significant spatial heterogeneity, forming low-value clusters in the built-up areas and northern desert regions, while high-value clusters were distributed across peripheral forests, grasslands, and alpine ice-snow zones. (2) Tourist activity footprints were predominantly concentrated within the built-up area, demonstrating a distinct outward expansion in a concentric pattern over time. (3) A significant negative correlation was observed at the citywide scale. Locally, the dominant response pattern was characterized by “High Service-Low Activity” decoupling, alongside localized “Low-Low” synergistic clusters. 【Conclusion】 It is recommended to leverage regional resource endowments to develop differentiated ecotourism products, including desert, forest hiking, grassland recreation, and alpine ice-snow tourism. Furthermore, enhancing tourism reception facilities, optimizing public transport and car rental systems, and improving the accessibility of ecological spaces are crucial to guiding the orderly extension of tourist footprints and achieving a balance between ecological conservation and tourism development.
