近五十年锡林郭勒盟东四旗气温变化分析 The Changing Temperature Analysis in the Four Banners of East Xilingol League during the Past 50 Years

本文选取锡林郭勒市东北部四个旗县东乌珠穆沁、西乌珠穆沁、锡林浩特市、阿巴嘎旗，1956年到2012年4个气象站点的年平均气温、季平均气温、年平均最高气温、年平均最低气温、年极端最高气温、年极端最低气温进行分析。运用一元线性方程等方法，对锡林郭勒东北四个旗县这四种气温进行比较。结果表明：所研究的这四种气温均呈不同速率的上升趋势，上升的幅度均大于全国近50年的增温率0.25℃/10a，表明研究区的气候也在逐渐变暖。 This paper selects four banners of east Xinlingol, including West Wuzhumuqin, East Wuzhumuqin, Xinlinhot, Abaga, analyzed from 1956 to 2012 four meteorological stations annual average tem-perature, average temperature, annual mean maximum temperature, average minimum temper-ature, extreme maximum temperature, annual extreme minimum temperature. Using Linear re-gression equation ways to make comparison between this four banners’s temperature, the results show that the research of four types of temperature is in the trend of rising amplitude, greater than 50 years rate of temperature throughout the country, meaning that the temperature in the study area is also getting warmer.
