中文摘要	文中利用内蒙古35个气象观测站整编的1971～2000年资料,研究了内蒙古及其各个生态类型区域的日平均气温稳定通过10℃的初日、终日、初终间日数和积温的空间变化、年际变化、年代际变化趋势.结果表明:内蒙古全区及各区域日平均气温稳定通过10℃的积温变化均呈显著增加趋势,全区范围内平均每十年积温增加95℃,初终间日数增加3.2天.其中,积温增加幅度最大是荒漠化草原区,平均每十年增加156℃;初终间日数增加幅度最大是荒漠化草原区,每十年增加6.9天;初日明显呈提前的趋势,初日在全区范围每十年提前了1.9天;终日呈推迟的趋势,终日在全区范围每十年推迟了1.4天.各区域的初终间日数和积温变化与全区相近,都呈明显的增加趋势.
英文摘要	Using the data of 35 observation stations during recent 30 years in Inner Mongolia, the changes tendency of beginning date, ending date, interval days between the first and last day and accumulated temperature above 10℃ were studied. The results showed accumulated temperature above 10℃ displayed an obvious increase tendency in Inner Mongolia and in different ecological types of areas. It was found that the accumulated temperature has increased about 95℃ and intervals of beginning day and ending day of≥10℃ has increased about 3. 2 days per decade averagely. The most distinct region is in deserted grassland areas where the accumulated temperature increase by 156℃ and the interval days between the first and last day of≥10℃ increases about 6.9 days per decade averagely. The first day in the whole area which displays an obvious ahead tendency is moving up earlier about 1. 9 days per decade. The tendency of the last day coming is later; the last day in the whole area comes later more than about 1.4 days per decade. The tendency of interval days between the first and last day and accumulated temperature is increasing in Inner Mongolia and different ecological type areas.
