基于MODIS遥感卫星数据，反演地表温度，研究内蒙古各城市昼夜城市热岛空间分布和季节变化特征。结果显示：（1）白天内蒙古西部地区城市热岛效应弱；中部地区除集宁外，城市热岛出现概率呈对半趋势，没有东部地区城市热岛效应强；东部地区城市热岛效应出现概率最多，以赤峰和通辽尤为显著。夜间全区城市热岛出现的概率比白天大，有些城市达到了100%的现象。（2）内蒙古城市热岛并没有表现出统一季节变化规律，白天，冬季出现城市热岛的有锡林浩特、海拉尔、集宁和通辽；夏季为热岛的城市有呼和浩特、乌兰浩特。夜间，呼和浩特全年热岛，基本全年热岛（除个别月份）的有集宁、通辽、乌海、乌兰浩特和锡林浩特；春季为热岛的是临河；秋季为热岛的有赤峰和东胜；热岛有季节变化规律的是巴彦浩特、海拉尔、包头。（3）呼和浩特夏季6-8月呈现热岛效应；冬季12月依旧表现为热岛，且夜间城市热岛更严重。（4）集宁除5月、7月、12月为冷岛，其余月份为热岛；7月白天为弱冷岛，夜间为热岛，城郊温差较小；冬季12月白天集宁市区为热岛效应，夜间集宁市区呈现弱冷岛效应。
The surface temperature was retrieved based on MODIS remote sensing satellite data, and the spatial distribution and seasonal variation characteristic of urban heat island in Inner Mongolia were studied. The results showed that:(1)The urban heat island effect is weak in western Inner Mongolia during the daytime. Except for Jining, the probability of urban heat island effect in the central region has half-and-half trend, which is not as strong as that in the eastern region. The urban heat island effect in the eastern region has the highest probability, especially in Chifeng and Tongliao. The urban heat island effect is more likely to appear at night than the day, some cities even reaching 100% probability. (2) Inner Mongolia urban heat island effect does not show uniform seasonal variation. In daylight, Xilinhaote, Hailar, Jining and Tongliao are likely to have urban heat island effect in winter. Huhhot and Wulanhaote are likely to have urban heat island effect in summer. In nighttime, Huhhot, Jining, Tongliao, Wuhai, Wulanhaote and Xilinhaote are experienced urban heat island effect yearly. Linhe has urban heat island effect only in spring and not other seasons. Chifeng and Dongsheng have urban heat island effect only in autumn and not other seasons. Bayanhaote, Hailaer, Baotou have seasonal variation. (3) On June, July and August, Huhhot shows obvious urban heat island effect, summer is also the season owns the most serious urban heat island effect. Urban heat island effect also shows in winter, and the nighttime urban heat island effect is more serious. (4) Except cold island effect in May, July and December, the rest months in Jining are heat island effect. A weak cold island effect is showed in daylight on July, and the temperature difference between the urban and suburbs is only 0.58℃. A heat island effect is showed in nighttime on July, and the temperature difference between the urban and suburbs is only 1.42℃. Urban heat island effect is showed in daylight in December. In December, the weak cold island effect is observed in nighttime.
