摘  要：
利用松桃国家基本气象站1957—2018年的地面气象观测资料,采用一元线性回归方程和数理统计等方法,对松桃县近62年来的气温、降水、日照、相对湿度等4个要素的变化特征进行分析。结果表明,松桃县近62年来平均气温呈现出波动缓慢上升的趋势,每10年上升0.076℃;年累积降水量呈现稍微下降的趋势,但下降不明显,基本保持平稳状态,但暴雨日数呈现出波动增多的趋势;松桃县每年日照时数呈现波动下降的趋势,下降趋势较为明显,下降率为6.124 5 h/年;平均相对湿度也呈现出缓慢减少的趋势。总体来说,松桃县近62年来气候变化比较平稳,但是暴雨天数增多,需要防范暴雨洪涝灾害带来的不利影响。

摘  要：
Based on the ground meteorological observation data from 1957 to2018 of Songtao national basic meteorological station,the change characteristics of temperature,precipitation,sunshine,relative humidity in Songtao County in the past 62 years were analyzed by using the methods of one-way linear regression equation and mathematical statistics. The results showed that the average temperature in Songtao County had been rising slowly in the past 62 years,rising by0.076℃ every 10 years. The annual accumulated precipitation showed a slight downward trend,and the decline was not obvious,but the number of rainstorm days showed a trend of increasing volatility. The annual sunshine hours showed a trend of fluctuation and decline,with a decline rate of 6.124 5 hours per year. The average relative humidity also showed a slow decreasing trend. Generally speaking,the climate change in Songtao County was relatively stable in the past 62 years,but the number of rainstorm days was increasing,so it was necessary to prevent the adverse effects of rainstorm and flood disasters.
