摘要
根据5个代表性台站的温度等级资料，得到了东北科尔沁地区1911－1988年区域平均的温度等级时间变化序列。这个地区冬季温度在年际、年代际和长期趋势上的变化与辽东半岛地区十分相似，但夏季温度的变化在各种时间尺度上同辽东半岛均存在较显著差异。本世纪科尔沁地区冬季温度和辽东半岛一样出现了明显增暖趋势，而夏季温度的变凉趋势却不如后者显著。
A major obstacle for regional climate change studies in China is the lack ofmeteorological stations with long time records. For Northeast China, for example, only adozen or so stations began to be in operation at the beginning of this century,and most ofthem had to stop recording during the l94o's due to the Sino-Japanese War- The Chinese A-cademy of Meteorological Science and Central Meteorological Station compiled a data set,The Temperature Grade Atlas for China (1911-1980),on the basis of the existing record inl984. Based on this data set, I calculated the area average temperature grade departure forHorqin Region,Notheast China for the last 80 years. The result shows a 0. 7℃ warming forwinter from 1911 to 1988,and a 0. 3℃ cooling for summer for the same period- Comparison ofthis result with our previous study for Liaodong Peninsula was made,and a general resem-blance was found,with the major difference being in summer temperature changes in that thecooling over Liaodong Peninsula was estimated to be 0. 6℃. The possible causes for the ev-ident winter warming and summer cooling in the central and southern Northeast China werediscussed. Also discussed are the hypothesized causes of the different cooling on the coastaland inland areas.
