以锡林郭勒盟及其周边地区17个气象站点1960年以来的月气温和降水量数据为基础,利用气象学与生态学知识,按照荒漠草原区、典型草原区、草甸草原区和农牧交错区4个生态地理区对锡林郭勒盟及其周边地区的气象站点进行分区归并,统计各区的De Martonne干燥度指数,在Matlab等软件的支持下,用小波分析的方法,研究各区年平均气温的周期性变化规律及各区之间的异同点。研究结果表明,在25-32a时间尺度上,随着时间的推移,锡林郭勒盟4个生态地理区年干燥度均呈现明显的周期变化,形成正负相间的震荡中心;草甸草原区和农牧交错区表现出干燥程度增加的趋势。总体上推测,2007年以后的15a左右时间,锡林郭勒盟的4个生态地理区的气候均将呈现比较干燥的状态。

Based on the monthly average temperature and precipitation data of 17 meteorological stations of Xilin Gol league and its surrounding areas since 1960.These meteorological stations were divided into four eco-zones such as desert steppe region,typical steppe region,meadow steppe region and farming-pastoral transition zone using the knowledge of meteorology and ecology.Then,the dryness index of each eco-zone was calculated.The periodic variation law of average temperature and similarities and differences point of every zone were studied using MATLAB software and wavelet analysis method.The results showed that the annual dryness index of the four eco-zones had obvious periodic variation,and formed the interphase center of oscillation by plus-minus as time goes on in time scale of 25-32 years.The dryness degree was increased in meadow steppe region and farming-pastoral transition zone.We could speculate that the climate of the four eco-zones will present a dry condition in the next 15 years from 2007 in Xilin Gol.
