• 摘要： 用方差公式、线性估计法、非参数检验法对洪泽地区 1961 一 2020 年气温要素进行趋势、突变等特征进行分析。得出：年平均最低气温距离年平均气温最靠近，年平均最高气温距离年平均气温最远。年平均气温呈波动上升。季平均气温也存在明显波动变化，春季平均气温呈波动上升，夏季平均气温为先下降后上升，秋季平均气温变化平缓，冬季平均气温变化倾向在四季中最大。气温年较差年际变化明显。年平均气温在 1994 年出现突变。
• Variance formula, linear estimation method and non-parametric test method are used to analyze the trend, abrupt change and other characteristics of temperature elements in Hongze region from 1961 to 2020. It is concluded that the distance between the annual mean minimum temperature and the annual mean maximum temperature is the closest, and the distance between the annual mean maximum temperature and the annual mean temperature is the farthest. The annual mean temperature fluctuates. The seasonal average temperature also fluctuated significantly. The average temperature fluctuated and increased in spring, decreased first and then increased in summer, changed gently in autumn, and changed the most in winter. The inter-annual variation of the annual temperature difference was obvious. There was a sudden change in the annual mean temperature in 1994.
