| 摘 要： | 内蒙古牧区地处中高纬度内陆区，受降水、气温、日照等气候条件的作用，草原地带性分布十分明显。在草原植被和气候条件的综合作用下，牧草对水分的需求和草地对水分的消耗也存在一定差异，研究我区各类天然草场的耗水量，揭示其供、耗水矛盾，不仅可为提高草地生产力提供技术指导，也可为牧区旱灾的评价提供依据。

| Abstract: | Influenced by climatic factors such as precipitation, air temperature and sunshine, the steppe region distribution is very distinct in the middle and high latitude inland of Inner Mongolia Pasturol areas. In addition, water requirement of grass and water consumption by grassland vary considerably due to overall impacts of steppe vegetation and weather conditions. Consequently, the research on water comsumption by natural pastures in Inner Mongolia and the reveal of the contradiction between water supply and water consumption, provide not only technical guidance for the improvement of grassland productivity, but also the basis for the evaluation of drought in pastoral areas. |
