伊春地区近60年气温与降水的气候变化特征分析

对伊春地区1961—2020年共60年的气温、降水量进行综合分析,初探伊春地区气候变化的部分规律,发现伊春全市年平均气温呈明显上升趋势,60年来平均气温升高了2.6℃,平均每10年升高0.38℃,特别是1989—2008年间变暖较为明显;降水量在1961—2020年间呈缓慢上升趋势,20世纪60年代、80年代初属于多雨年阶段,1995—2004年10年间属于少雨年阶段,2009—2020年降水量逐年增多。通过对伊春近60年的气温、降水量变化研究,可以为防灾减灾、趋利避害、发展生产及经济建设提供气候方面的参考依据。

By using the meteorological observation data of temperature and precipitation of 60 years from 1961 to 2020 in Yichun area to make a comprehensive analysis,and make a preliminary study on the partial regularity of climate change in Yichun,it is found that the annual average temperature in Yichun has increased by 2.6℃in the past 60 years,and by an average increase of 0.38℃every 10 years,especially from 1989 to 2008,which is consistent with the warming.The precipitation increased slowly from 1961 to 2020.It was a rainy year in the 1960s and early 1980s,and a dry year from 1995 to 2004.The precipitation increased year by year from 2009 to 2020.These studies provide some climate-related references for disaster prevention and mitigation,seeking benefits and avoiding harms,and developing production and economic construction.
