全球气候变化背景下的区域气候变化——以重庆市近代以来气候变化为例

The Regional Climate Changes Under the Global Climate Changes --Taking Chongqing for Example

区域性的气候变化是在全球气候变化的背景下产生的 ,但由于区域内本身的自然影响因素的特殊性 ,使得即使在同一全球气候变化趋势下 ,各区域的气候变化也不尽相同 ,各具特点。本文初步研究了重庆市近几十年的基本气候变化规律 ,发现在 2 0世纪 80年代重庆市的气候变化特点是持续的低温 ,与当时全球气温的稳步上升形成了鲜明的对比。

The regional climate changes take place against the background of the global climate changes. However ,the particularities of natural factors in different regions lead to variations even in the same global climate changing tendency. In this thesis the author has made a preliminary research on the basic rules of climate changes in Chongqing in recent decades and discovered the continous low temperature in the 80′s in the twentieth century, which contrasted sharply with the steadily rising of the global temperature at that time.
