摘要
为了解气候变化背景下灵璧县农业气候资源特征,利用灵璧县国家气象站1957—2020年的气温、降水量、日照时数等资料,采用气候倾向率和农业保证率方法,分析灵璧县农业气候资源特征。结果表明:80%保证率下,日平均气温稳定通过≥0℃和≥10℃的初日均呈提前趋势,终日均呈后推趋势,持续日数均呈增加趋势;日平均气温稳定通过≥0℃和≥10℃的初、终日间降水量均呈增加趋势,积温呈明显增加趋势,日照时数则呈明显减少趋势。
In order to understand the characteristics of agricultural climate resources in Lingbi county under the background of climate change, the characteristics of agricultural climate resources in Lingbi county were analyzed by using the data of temperature, precipitation and sunshine hours of the National Meteorological Station of Lingbi county from 1957 to 2020 and the methods of climate tendency rate and agricultural guarantee rate.The results showed that under the guarantee rate of 80%, the daily average temperature was stable, the first day of ≥ 0℃ and ≥10℃ showed an early trend, the whole day showed a backward trend, and the number of continuous days showed an increasing trend;The daily average temperature was stable,and the precipitation at the beginning and end of the day when the temperature was≥0℃and≥10℃ showed an increasing trend, the accumulated temperature showed an obvious increasing trend, and the sunshine hours showed an obvious decreasing trend.
