| 摘 要： | 为了合理开发利用气候资源，给草原畜牧业生产的分区管理提供科学依据，文章对内蒙古草原气候特点及气候对牧草生长、畜种分布和土壤环境的影响进行了分析，发现内蒙古气候湿润度的某些等值线与土壤带的分界线几乎完全重合，表明土壤带的形成与气候条件密切相关。而气候和土壤环境是草场类型及其生态系统的主要影响因素，因此以气候湿润度为主要依据，结合内蒙古土壤带的水平分布特征，进行草原生态类型区域的划分不仅具有合理性，而且具有稳定性。指出近年来的气候增暖以及由此引起的其他气候变化，虽使草原生产力有一定的提高，但并未使内蒙古草原的生态类型有所改变。

| Abstract: | In order to develop and utilize reasonably climate resources and offer a scientific basis for the sub-area management of livestock production over grasslands, an analysis was made of the Inner Mongolia grassland climate characteristics and effects of climate on the growth of pasture grass, the distribution of domestic animal breeds and the soil environment. It is found that some isolines of climatic moisture are almost superposed with the boundaries of soil, which indicates that the formation of soil zones is closely related to climatic conditions, and climate and soil environment are main influence factors for pasture types and the ecosystem. Based on the climatic moisture, in combination with the distribution characteristics of soil over Inner Mongolia, a regionalization was carried out of grassland ecological types, which is not only rational, but also stable. It is pointed out that the climatic warming and the resulting changes in recent years improved, to some extent, the productivity of the grasslands, but not changed the ecotype in Inner Mongolia. |
