摘要: 基于随州市2个国家气象站1959-2018年60年的逐日地面气象观测数据,计算并分析了气候变化背景下该地区中稻生长季内热、光、水等农业气候资源的变化特征。结果表明,随州市≥10 ℃积温气候倾向率为30.6 (℃·d)/10年,增加趋势显著;广水市≥10 ℃积温气候倾向率为82.5 (℃·d)/10年。随州市≥20 ℃积温增加趋势不显著;广水市≥20 ℃积温增加趋势显著,≥20 ℃积温气候倾向率为89.2 (℃·d)/10年。日照时数呈显著减少趋势,随州市日照时数气候倾向率为-35.4 h/10年,广水市日照时数气候倾向率为 -25.3 h/10年。随州市太阳辐射减少趋势显著,太阳辐射气候倾向率为-42.4 MJ/(m2·10年),而广水市太阳辐射减少趋势不显著。年际间生长季内降水量波动大,变化趋势均不显著。随州市参考蒸散量减少趋势显著,参考蒸散量气候倾向率为-24.7 mm/10年,广水市变化趋势不显著。

Abstract: Based on the daily ground surface meteorological observation data of two national meteorological stations in Suizhou city from 1959 to 2018, the variation characteristics of agricultural climate resources such as sunshine, temperature and precipitation in this region under the background of climate change were calculated and analyzed. The results showed that the climatic tendency rate of accumulated temperature ≥10 ℃ in Suizhou was 30.6 (℃·d)/10 years, with a significant increasing trend. The trend rate of accumulated temperature ≥10 ℃ in Guangshui city was 82.5 (℃·d)/10 years. There was no significant increase trend of accumulated temperature ≥20 ℃ in Suizhou city; The cumulative temperature ≥20 ℃ had a significant increasing trend, and the climatic tendency rate ≥20 ℃ was 89.2 (℃·d)/10 years. The climate tendency rate of sunshine hours in Suizhou city and Guangshui city were -35.4 h/10 years and -25.2 h/10 years, respectively, and both showed a significant decreasing trend. The trend of solar radiation reduction in Suizhou city was significant, and the trend rate of solar radiation climate was -42.4 MJ/(m2·10 years), while the trend of solar radiation reduction in Guangshui city was not significant. The annual precipitation fluctuated greatly in the growing season and the variation trend was not significant. The climate tendency rate of reference evapotranspiration in Suizhou city was -24.7 mm/10 years, and the variation trend of reference evapotranspiration in Guangshui city was not significant.
