摘要
总结了对近百年中国气候变化的研究。指出由于缺少系统的观测资料,影响了对气候变化的估计。最近利用史料、冰芯δ^(18)O及树木年轮等代用资料补充观测资料的不足,建立了188-1996年中国平均气温及降水量曲线。重点讨论了气候变暖及干旱两个问题。
Studies on climatic change in China during the last one hundred years are reviewed. It is indicated that scanty of observational data has greatly hindered the understanding of climatic change. Recently, a series of proxy data, including historical documents, ice core δ18O and tree-ring data have been used in reconstruction of annual temperature and precipitation series of China for 1880 - 1996. Warming of climate and development of droughts in China are examined according to the constructed series.
