摘要(Abstract)：

利用中国气象中心160站点的实际观察资料,对中国半个世纪的气温变化进行了分析。通过利用插值法对各个站点的数据进行处理,分别做出50年代和90年代多年平均的冬夏季节以及年等温线。通过对比每个季节不同年代的等温线,发现中国的年等温线分布态势由夏季气温分布主宰。在这半个世纪中中国冬季和夏季等温线的分布以及变化存在很大的不同:冬季等温线基本上向高纬度方向移动,而夏季以高温和低温中心为基点,向高温或低温方向移动。夏季等温线变动幅度相对小,但夏季存在区域性的降温现象。在幅度上,等温线移动基本上是由南向北普遍增大,西北地区最大。最后对等温线的变化所揭示的气温变化规律以及气温变化的时空差异进行了机理上的分析和讨论。

关键词(KeyWords)： 等温线;季节变化;高原—盆地效应;人类活动
