【摘要】 利用内蒙古地区94个站1951～1995年年平均气温资料,进行了模糊聚类分区,把全自治区分成4个区,即西部区、中部区、东南部区和北部区,对4个区的年季气温的变化做了分析,结果表明,变暖主要是在20世纪80年代以后,不同年、季节的气温变化趋势也有明显差异,特别是冬、春季增暖较明显,但夏季增暖不显著,因进入80年代以后,冬季寒冷日数明显减少。更多还原

【Abstract】 Employing the data of the annual average temperature between 1951-1995 collected through the 94 stations of Inner Mongolia, by adopting the method of fuzzy cluster analysis, that is to divide the whole landscape of Inner Mongolia into four parts, the west-part, the middle-part, the south-eastern part and the north part, this paper exams the seasonal temperature changes on the year basis. The conclusions show,especially after the 1980,s,There is also an evident difference in four seasons,especially the warm trend is evident in winter、spring than in summer After 1980,s,the cold duration evidenrly decreases更多还原
