| 摘 要： | 运用气候变化检测、监测和指数专家小组制定的与温度相关的气候变化指数,对1961～2008年我国278个气象站温度指数的空间特征进行了研究。结果表明,冰点日数从西北向东南逐渐较少,全国范围内绝大部分地区冰点日数呈减少趋势;夏季日数普遍在50d以上,整个东部地区,除了东北大部分地区外,夏季日数都在100d以上,全国范围内大部分地区夏季日数呈增多趋势;我国的生长期普遍在150d以上,自北而南随着纬度的降低生长期逐渐增加,研究的278个站点中,有236个站点生长期的趋势系数为正值。

| Abstract: | The paper elicits some conclusions over China based on the temperature indices of climate change that established by the joint CCl/CLIVAR/JCOMM Expert Team (ET) on Climate Change Detection and Indices (ETCCDI):the number of freezing-day decreases gradually from northwest to southeast,the trend of the number of freezing-day is lessened over the most of China; the number of summer-day is more than 50 days at large over China,and is all more than 100 days over the east of China except for the most of Northeast,the trend of the number of summer-day is increased in a great measure over the most of China; the period of growth exceed generally 150 days ,the trend of that increased generally from north to south that gone with decrease of latitude,the trend coefficient of the period of growth is positive that extended all over 236 stations of 278 stations in this research. |
