      摘要: 溫度變化是全球變化研究中非常重要的基礎(chǔ)性問(wèn)題,在中國(guó)近百年溫度變化方面,十幾年來(lái)已取得了明顯進(jìn)展,這首先表現(xiàn)在建立了若干條全國(guó)平均氣溫序列,而幾條主要序列間的相關(guān)系數(shù)在0.73~0.97之間。同時(shí),這些進(jìn)展也表現(xiàn)在基礎(chǔ)資料質(zhì)量提高、空間覆蓋面擴(kuò)大、序列均一性改善以及結(jié)果可靠性提高等方面。對(duì)多序列進(jìn)行綜合分析得到的新結(jié)果顯示,1906-2005年中國(guó)的年平均氣溫上升了(0.78±0.27)℃,2007年是我國(guó)近百年來(lái)最暖的一年;代表性分析顯示,現(xiàn)有的幾條中國(guó)溫度序列中除覆蓋完整的序列外,其他序列在1920或1930年代以前可能主要反映中國(guó)東部變化情況,但在此之后則能較好地代表全國(guó)大部分地區(qū)的氣候變化特征。

      Abstract: Temperature change is of great importance in global change science. Remarkable progress has been made in studies of the temperature change in China during the recent 100 years or more. Some time series provide surface air temperatures averaged over China. Correlations between the series range from 0.73 to 0.97. The achievements mainly include the following: improving the quality, increasing the coverage of data, raising the homogeneity of time series and enlarging the reliability of the results etc. Analysis shows that the warming rate of annual mean temperature in China during 1906-2005 is (0.78±0.27)℃; 2007 is probably the warmest year. However, most of the series except those with complete coverage mainly reflect the temperature change over eastern China before the 1920s or 1930s, so caution must be taken in examination of temperature change.

      Key words: recent 100 years, climate change, air temperature series, estimation of warming rate, global warming
