摘　　要：通过对贵州高寒山区天然草地改良前后植被覆盖度、草群高度、产草量、可食牧草与毒草个体数比例、放牧羊增重量等进行监测,系统分析,客观评价。结果表明,实施天然草地改良,对未退化、轻度退化、中度退化和严重退化草地在一定程度上都可提高植被覆盖度、增加草群高度和产草量,同时,增加可食牧草在与毒草个体数比例,使得草原草地生态发生显著变化,促进草地的可持续性利用,产生良好的生态效益及社会经济效益。The vegetation coverage,the height of grass group,the yield of grass,the ratio of individual number of edible herbage and poisonous herbage,and the weight gain of grazing sheep were studied before and after the improvement of natural grassland in Alpine region of Guizhou Province.The results showed that the natural grassland improvement could increase the coverage of vegetation,the height of grass group and the yield of grass in the non-degraded,slightly degraded,moderately degraded and severely degraded grassland,the increase of the ratio of edible herbage to poisonous herbage makes the grassland ecology change significantly,promotes the sustainable utilization of grassland,and produces good ecological and social economic benefits.
