新华社加德满都5月23日电（记者张平）珠穆朗玛峰“巅峰之芯”中尼联合科考队近日成功从尼泊尔一侧登顶珠峰，并开展冰芯钻取等科学采样工作，完成了人类首次珠峰顶峰透底冰芯样本钻取。

目前，全体科考队员已安全下撤至珠峰南坡大本营，并在下撤途中开展了多海拔梯度冰芯、雪芯样本采集。相关样本将按照低温保存要求转运至实验室，用于研究世界最高区域气候环境变化、冰冻圈变化和高海拔大气环境记录。

科考队队长、冰川工程博士温旭23日对记者表示：“这项任务的意义不仅在于登顶，更在于我们在海拔8848.86米的极端环境中，完成了连续的科学作业。顶峰冰芯样本的取得，为后续研究珠峰极高海拔区域气候环境变化、冰冻圈变化和高海拔大气环境记录提供了重要实地样本。”

温旭高度肯定了尼方队员对这次任务的贡献。“他们的攀登能力强，对高海拔恶劣环境的适应和应对经验也更加丰富，对完成此次冰芯钻取任务起到了关键支撑作用。”

本次科考首席科学家徐柏青表示，珠峰顶峰是地球地理最高点，是人类观测的重要空白。此次获取的顶峰冰芯及多海拔梯度样本，将为揭示世界最高区域气候环境变化、理解极高海拔大气环流和物质传输过程提供关键样品。

“巅峰之芯”项目由中国科学院加德满都科教中心与天津市极致应对气候变化促进中心（极地未来）联合发起。据科考队介绍，取得顶峰透底冰芯是本次科考的重要突破；而沿下撤路线持续开展多海拔梯度样本采集，则是建立完整高海拔气候环境证据链的关键环节。相关样本有助于科学家进一步理解极高海拔区域气候环境变化、污染物向高海拔区域传输路径以及珠峰南北坡气候响应差异等关键科学问题。
