摘　　要：文章采用变点分析方法对阜新地区的阜新站和彰武站近62a降水日量变化特征进行分析,分析表明:阜新站和彰武站近62a日降水分别呈现递增和递减变化,但变化趋势性较弱,夏季降水量均有所增加;90年代日降水量发生突变,大雨量级以上的暴雨频次增多。The change point analysis method is used to analyze the characteristics of daily precipitation changes in Fuxin and Zhangwu stations in Fuxin area in the past 62 years.The analysis shows that the daily precipitation at Fuxin and Zhangwu stations in the past 62 years has shown increasing and decreasing changes,however,the trend of change was weak,and the precipitation increased in summer.In the 1990s,there was a sudden change in daily precipitation,and the frequency of heavy rains above the heavy rainfall level increased.
