摘要
采用ＨＯＬＤＲＩＤＧＥ的生命地带分类系统对内蒙古的生命地带类型划分、分布及其对未来气候变化的响应进行了研究．确定了现代气候条件下内蒙古生命地带的八个类型：森林及森林草原带、暖温性森林带、中温性草甸草原带、中温性典型草原带、暖温性草原带、荒漠草原带、草原化荒漠带和荒漠带．通过两种气候变化方案的分析，阐述了它们对未来气候变暖的响应趋势．结果表明，类型和面积发生了的显著的变化．寒温和中温类型的面积急剧减少，暖温类型的面积成倍增加．在较高温度的方案下，出现了两个新的类型：极旱荒漠带和暖温灌丛草原带．另一方面，生命地带的空间位移也十分明显，总的趋势是向北扩展．
Holdridge Life Zone Classification System is used to study types, distribution and responds of life zones in Nei Mongol to likely climate changes. Eight life zones are determined under the current climate condition, forest and forest steppe, warm forest, temperate meadow steppe, temperate typical steppe, warm steppe, desert steppe, steppe desert, and desert. Impacts of two climate change scenarios on those life zones, both in area and in shift are analyzed. On the one hand, life zone types and areas change greatly. The area of cold temperate type and temperate types decrease remarkably, meanwhile area of warm types increase at a rate of many times. In addition, two new life zone types appear in a high temperature scenario, heavily dry desert and warm shrub steppe. On the other hand, spatial migrations of life zones take place obviously. In general, the trend of northward overspread is in dominant. Temperature plays a significant role in those changes mentioned above.
