摘　　要：利用长白山的气象数据,分析长白山1958—2015年平均温度和降雨量的变化特征.结果表明:长白山年平均温度呈现上升趋势,线性增温率为0.392℃/10 a,四季和各月份的平均温度均呈现上升的趋势.其中,冬季的增温率最高,为0.569℃/10 a,其次是秋季和春季,夏季的增温率最低,为0.222℃/10 a;长白山年降雨量变化不明显,整体呈现微弱增加趋势,降雨量倾向率为2.28 mm/10 a.其中,四季的降水量呈现不同的趋势,春季、夏季和冬季的降雨量呈现增加的趋势,而秋季的降雨量呈现下降的趋势,降雨量倾向率为-3.9 mm/10 a.在过去的58a,长白山总体气候呈现暖干化趋势.Based on1958-2015monthly meteorological data,the characteristics of mean temperature and precipitation change in Changbai Mountain were analyzed.The results indicated that the annual mean temperature showed the increasing trend from1958to2015,and increased by0.392℃/10a.All of the seasonal and monthly temperatures showed increasing trends.Compared with each season,the rate of temperate in winter increased most quickly(0.569℃/10a),followed by autumn and spring,and summer increased most slowly(0.222℃/10a).The annual precipitation in Changbai Mountain displayed a slight increase,and increased by2.28mm/10a,but the precipitation variation was not obvious.The seasonal precipitation showed various trends.The spring precipitation,winter precipitation and summer precipitation showed increasing trend,but the autumn precipitation showed decreasing trend with a rate of-3.9mm/10a.Above all,the climate trended to be warmer and dryer in the past58years.
