Research on changes in cryosphere services is crucial for the responsible management of cryospheric resources and for fostering sustainable development in Social-Ecological Systems (SESs) impacted by the cryosphere. While previous research has primarily focused on quantifying cryospheric change through Cryosphere Service Value (CSV), the impact of cryosphere service change on Social-Ecological Systems Resilience (SESR) remains unclear. This study considers the Qilian Mountains as a cryosphere system and assesses the changes in its service value from 2000 to 2020. It also establishes a framework to analyze the spatial-temporal variations in resilience within the Qilian Mountains Area in China (QMAC) and investigates the impact of changes in cryosphere services on SESR. The findings indicate that (1) the CSV exhibited a decreasing trend followed by an increase from 2000 to 2020, with minor increases observed in the three northern inland river basins and substantial increases in other areas; (2) the resilience in QMAC improved consistently, establishing a spatial pattern characterized by higher resilience in the west and lower resilience in the east, as well as higher resilience in the north and lower resilience in the south; (3) the effects of changes in cryosphere services on SESR demonstrate significant spatial-temporal patterns, the decline in climate regulation service has a notably negative impact on ecological resilience, while the increase in value from aesthetic appreciation and tourism service positively boosts economic resilience; and (4) changes in cryosphere services affect social resilience by influencing residents' livelihoods, with more pronounced effects on SESs in areas with high land use intensity. This research provides a research avenue for examining how cryosphere service change impacts SESR and offers practical experience for promoting the stability of SESs and developing sustainable development policies in regions affected by the global high-mountain cryosphere amid climate change.
研究冰冻圈服务的变化对于冰冻圈资源的合理管理以及促进受冰冻圈影响的社会生态系统（SESs）的可持续发展至关重要。虽然以往的研究主要集中在通过冰冻圈服务价值（CSV）来量化冰冻圈变化，但冰冻圈服务变化对社会生态系统弹性（SESR）的影响仍不明确。本研究将祁连山视为一个冰冻圈系统，评估了其2000年至2020年的服务价值变化。还建立了一个框架来分析中国祁连山区（QMAC）内弹性的时空变化，并研究冰冻圈服务变化对SESR的影响。研究结果表明：（1）2000年至2020年期间，CSV呈先下降后上升的趋势，北部三个内陆河流域略有增加，其他地区大幅增加；（2）QMAC的弹性持续改善，形成了西部弹性较高、东部弹性较低，以及北部弹性较高、南部弹性较低的空间格局；（3）冰冻圈服务变化对SESR的影响呈现出显著的时空格局，气候调节服务的下降对生态弹性有显著的负面影响，而审美欣赏和旅游服务价值的增加则对经济弹性有积极的促进作用；（4）冰冻圈服务变化通过影响居民生计来影响社会弹性，对土地利用强度高的地区的SESs影响更为明显。本研究为探讨冰冻圈服务变化如何影响SESR提供了一条研究途径，并为促进SESs的稳定性以及在气候变化背景下受全球高山冰冻圈影响的地区制定可持续发展政策提供了实践经验。
