| 摘 要： | 以洞庭湖区24个气象站1952-2010年的平均气温资料为基础,利用气候倾向率、Mann-Kendall突变检验法和小波分析等方法,分析了洞庭湖区的气温变化特征.结果表明:洞庭湖区年平均、冬季、春季和秋季气温均呈显著上升趋势,增温速率尤以冬季和春季为甚.除夏季外,年平均和其他各季气温在1990s,先后发生增温性突变.高温日数呈上升趋势,但显著性不明显,低温日数下降趋势非常显著.除夏季外,年平均和各季异常冷年,基本出现在1950s至1970s,异常暖年,均出现在1998年以后.除夏季外,各季气温均存在准9a周期. |

| Abstract: | Based on average temperature data from 24 weather stations in Dongting Lake area from 1952 to 2010, the methods of climatic tendency, Mann-Kendall jump test and wavelet analysis are used to analyze the temperature change characteristics of Dongting Lake area. The results show that the temperatures of average annual, winter, spring and autumn in Dongting Lake area tend to go up; winter and spring warming rates are remarkable. Except summer, the average annual temperature and temperatures in other seasons in 1990s have warming mutation. High temperature days show ascendant trend, but the significance is not apparent; low temperature days go down significantly. Except summer, temperatures in the annual cold anomaly years of average and each season occur from 1950s to 1970s, while the warm anomaly years appear later in 1998. In addition to the summer, the temperature in each season follows nearly 9 a cycle. |
