摘要: 为研究荆州市气候时空变化特征,利用荆州市6个国家气象站1961—2018年日平均气温、逐日降水量和日照时数资料,采用线性倾向估计法、累积距平法、M-K突变检验法分析了荆州市主要气候要素时空变化特征。结果表明,近58年来荆州市增温趋势非常明显,20世纪90年代以来尤为显著;降水量总体呈增加趋势,但年际间波动较大;年日照时数明显减少。荆州市增温主要在2—5月和9—12月;7月降水量增加趋势明显,降水量减少主要集中在秋季;夏季日照时数明显减少是荆州市光照变差的主要原因。荆州市各站气候要素变化趋势基本一致,仅松滋站年降水量呈减少趋势,与荆州市整体变化趋势相反。随着气候变暖,荆州市热量资源明显增加。

Abstract: In order to study the temporal and spatial variation characteristics of climate in Jingzhou city, the data of average daily temperature, daily precipitation and sunshine duration from 1961 to 2018 of six national meteorological stations in Jingzhou city were used to analyze the temporal and spatial variation characteristics of major climatic factors in Jingzhou city by using linear tendency estimation method, cumulative anomaly method and M-K mutation test method. The results showed that in the past 58 years, the trend of temperature increase in Jingzhou city, especially since the 1990s; The precipitation showed upward trend, while the annual fluctuation was large; The annual solar duration decreased significantly. The temperature increase of Jingzhou city was mainly from February to May and from September to December. The precipitation increase trend was obvious in July, and the precipitation decrease was mainly in autumn; The decrease of sunshine duration in summer was the main reason for the poor illumination in Jingzhou city. The trend of climate change in stations Jingzhou city was basically the same, only the annual precipitation of Songzi station showed a decreasing trend, which was contrary to the overall change trend of Jingzhou city. With the warming of the climate, the heat resources of Jingzhou city increased obviously.

Key words: climatic elements, characteristics of change, abrupt change test method, Jingzhou city
