Abstract:

基于微气象学理论的涡度相关通量观测技术实现了对生态系统尺度的生产力、能量平衡和温室气体交换等功能和过程的直接测定,特别是全球尺度通量塔观测网络的联合观测是实现从生态现象观察和生态要素观测跨越到全球尺度生态系统功能状态变化观测的重大突破。本文回顾了中国陆地生态系统通量观测研究网络(ChinaFLUX)的创建及发展历程,系统介绍了ChinaFLUX的科学目标和设计理念、观测技术体系、观测数据的标准化处理及长期积累;综合评述了ChinaFLUX在陆地生态系统碳-氮-水的收支评估和交换过程的环境响应、碳通量时空格局及其形成机制等方面所取得的主要研究进展。最后,在探讨未来全球尺度通量塔观测网络发展趋势的基础上,提出了ChinaFLUX的主要发展方向、关键科学问题与未来工作重点,为中国通量观测研究事业的进一步发展提供理论参考。
