摘要: 气象台站历史沿革信息包含了可能影响气候资料序列均一性的重要信息, 是分析、检验、订正气候资料序列的科学参考依据。文章介绍了气象台站历史沿革信息的基本内容及我国气象台站变动的基本情况, 通过对气象观测资料比较分析, 说明台站迁移、环境变化、观测仪器类型以及观测时制改变, 直接影响到观测记录的比较性和连续性, 对长年代气候资料序列的均一性也有不同程度的影响。Abstract: Information of meteorological station's historical evolution includes various messages that maybe impact on homogeneity of sequence of climatological data. They are important reference bases for analyzing and verifying as well as correcting sequence of climatological data. Introduced herein are both the basic content of meteorological station historical evolution and the basic condition of meteorological station change of our country. By contrast analyses of meteorological observational data, the change of meteorological stations historical evolution impacts on homogeneity of sequence of climatological data is discussed. The results show that the change of meteorological station historical evolution is one of important facts which causes inhomogeneity of climatological data sequence. Especially, the movement of observational station and change of station's environment as well as change of observational instrument type or observational time has directly effect on continuity of observational records and the homogeneity of long sequence of climatological data. So, the archives of meteorological station historical evolution are of significance for studying the homogeneity of climatological data sequence.
