| 摘 要： | 冰冻圈独特而极端的生态环境蕴藏着丰富的微生物资源，保存了关于古微生物多样性和进化历史的珍贵记录。气候变化和人类活动正在对全球生态系统造成显著影响，冰冻圈加速消融缩减使原本冻存其中的微生物被“解封”，一些微生物适应新的环境条件从而复苏存活，随之构成对生态环境和人类健康的未知威胁。为此，亟待联合多学科研究力量，调查研究冰冻圈微生物资源，解析其中病原微生物的致病和传播机制，充分评估休眠微生物复苏释放带来的生物安全风险。

| Abstract: | The unique and extreme ecological environment of cryosphere acts as a gigantic reservoir of microorganisms, which preserves precious records of the diversity and evolutionary history of ancient microbes. Climate change and human activities have made significant impacts on the ecological system. Global warming causes melting of the cryosphere that remained frozen for thousands of years and releases microorganisms, some of them are recovered to life and constitute a potential threat to the ecological environment and human health. It is urgent to combine multidisciplinary research forces to investigate the microbial ecology of cryosphere, analyze the microbe pathogenesis and transmission mechanisms, as well as evaluate the biosecurity risks caused by the reboot of dormant microorganisms. |
