Abstract

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.

Key words: climate change, mid-season rice, agricultural climate resources, Suizhou city
