摘　　要：西部草原是中国西部地区居民的主要生活生产资料来源。多年来,受超载过牧、滥垦、滥挖、人口增长等因素的影响,草场大面积沙化和毒草化,使西部地区的自然生态环境遭受严重破坏,制约了西部地区畜牧业生产的可持续发展。毒草的迅速蔓延是造成草地生态失衡的重要生态学问题之一,是草地退化的一个重要指标。笔者在对文献资料分析、归纳的基础上,就中国西部草地近几十年的毒草灾害状况,毒草种类与分布,毒草综合防治及合理利用做以综述。Western grassland is the main source of living and means of production of western inhabitants. For many years, desertification and poisonous-weeds growth in grassland were resulted from over-grazing, over-reclaiming, over-spading and population growth. And western natural ecological environment is destroyed severely. Meanwhile, it has restricted the sustainable development of animal husbandry. The fast spreading poisonous-weeds, which caused grassland ecology unbalance, is one of the considerable bioecology problems and an important index of grassland degeneration. Based on analysis and induction of previous data, this article introduced the situation of poisonous-weeds disaster of western grassland in recent decades, category and distribution of poisonous-weeds, integrated control and reasonable utilization.
