中文摘要:
      东北地区是我国受全球气候变暖影响增温最显著的地区之一,有其独特的气候变化特点。利用东北地区建国以来较密集的气象观测资料,运用Yamamoto检测、趋势系数、气候倾向率等方法分析了该区域近44 a来平均、最高、最低气温的时空变化特征和规律,并初步探讨了这些变化的差异和可能影响因素。结果表明:近44 a来,东北地区平均气温存在明显的变暖倾向,气候变暖趋势存在着季节性和地域性差异。冬季增温最强,秋季增温最弱;区域变化表现为在区域中心区域,即吉林、黑龙江、内蒙古三省交界区增温趋势最明显,辽宁中部和内蒙古东部的中心靠近边境区域为增温较弱的地区;最低气温的增温率是最高气温的2倍左右。
英文摘要:
      Northeast lies on the highest latitude in China.Its warming trends is one of the most remarkable area of climate change under the background of global warming, and has particular climate change. The data of denser station in Northeast China since the establishment are employed to analyse the climate change of the average and extremum temperature during recent 44 years with Yamamoto check method.Climate trend coefficients, etc.the possible effects of this change are discussed preliminarily. The results show that warming trend exists under the area. The warming trends have the season difference and region difference.It behaves stronger in winter and weaker in autumn. The increment of minimum temperature is twice of that of maximum.
