| 摘 要： | 利用1956-1999年湖南省洞庭湖区和湘中丘陵区各三个站点44年的月平均气温资料,采用气候趋势系数和气候倾向率的方法,对1956年以来两地区的气温变化特征进行了分析与比较。结果表明,从年变化来看,两地区年气温变化趋势基本相同,但是洞庭湖区气温上升趋势明显,达到显著性检验,而湘中丘陵区只是一种随机振动;从季节变化来看,夏季两地区气温都呈下降趋势,但湘中丘陵区变化幅度大于洞庭湖区。

| Abstract: | Based on the monthly mean temperature data from respective 3 stations of Dongting Lake area and hilly area of Central Hunan in the recent 44 years(1956-1999),and using climate tendency coefficient and climatic trend rate,the variation characteristics of temperature in the two areas are analysed and compared.The results show that the annual temperature changing trend is nearly the same in the two areas,but the ascending trend of Dongting Lake area is more significant.while there is only a slight increasing trend in hilly area of Central Hunan;the summer temperature has a descending trend in the two areas,but it has a higher amplitude in Dongting Lake area than that in hilly area of Central Hunan. |
