Ecosystem vulnerability is an ecological response of the environment to external damage. Studying the influencing factors and spatiotemporal changes of ecosystem vulnerability is helpful to maintain ecological balance. At present, studies on ecosystem vulnerability are relatively homogeneous and rarely integrate climate change and human activities. Based on a habitat-function framework, this study analyzed the response of ecosystem vulnerability on climate change and human activities in the Poyang Lake City Group (PLCG) in 2010, 2015 and 2020. The spatial agglomeration of ecosystem vulnerability has been analyzed by using GeoDa model. The interaction of factors on ecosystem vulnerability have been analyzed by using geographical detector. It can be seen that the ecosystem vulnerability of the PLCG have increased from 2010 to 2020. The impacts of climate change to the ecosystem vulnerability have showed a positive correlation. Meanwhile, the key factors leading to the change of ecological vulnerability are still human activities. This methodology demonstrates a high level of robustness when applied to other research domains. This research is conducive to maintaining the integrity of the ecosystem, realizing the development of man and nature, and promoting the sound and rapid development of economic society.
生态系统脆弱性是环境对外界损害的生态响应。研究生态系统脆弱性的影响因素及其时空变化，有助于维持生态平衡。目前，对生态系统脆弱性的研究相对同质，很少将气候变化和人类活动结合起来。基于生境-功能框架，本研究分析了 2010 年、2015 年和 2020 年鄱阳湖城市群（PLCG）生态系统脆弱性对气候变化和人类活动的响应。利用 GeoDa 模型分析了生态系统脆弱性的空间集聚。利用地理探测器分析了各因素对生态系统脆弱性的相互作用。可以看出，PLCG 的生态系统脆弱性从 2010 年增加到 2020 年。气候变化对生态系统脆弱性的影响呈正相关。同时，导致生态脆弱性变化的关键因素仍然是人类活动。该方法在应用于其他研究领域时具有较高的稳健性。本研究有利于维护生态系统的完整性，实现人与自然的协调发展，促进经济社会的健康快速发展。
