中文摘要: 本文分析了近39年来中国的年与各季气温变化趋势,发现有变暖趋势。全国39年平均增暖大约0.23℃,其中冬季变暖最明显,大约变暖0.78℃,其次为春季,大约为0.34℃,而秋季变暖仅0.06℃,夏季39年有变冷趋势,大约变冷0.27℃。本文对中国城市化影响气温变化做了较深入分析。研究表明,近39年来,大城市年平均增暖明显,变暖大约0.27—0.45℃,而小城市变暖很少,39年平均变暖大约0.04—0.12℃。文中对各季各类城市气温在39年来的变化亦做了类似分析。

Abstract:The changes of temperature in China in the last 39 years have been studied. It is noticed that the temperature is increased by about 0.23℃ in China in the last 39 years. It is found that the most obvious warming occurs in winter time which is 0.78℃ increment and the secondary warming is a 0.34℃ increment, occuring in spring. But a cooling trend is presented in summer, which shows a -0.27℃ drop. Here the effects of the urbanization in China are also analysed. The annual temperature rising in the bigger cities is much more obviously found than that in the smaller cities in the last 39 years.
