摘　　要：同德县43．54万hm2天然草地中退化草地约占45．4％，而严重退化的“黑土型”退化草地占17．7％，并且由于超载过牧、鼠虫危害等因素，呈逐年扩大趋势。因此，对这类草地进行综合防治的探讨势在必行。根据同德县实际，提出了限制载畜量、建立人工草地等防治措施。There are 435400ha natural pasture grassland which is 45. 4%degraded grassland of total area in Tongde county,and serious 'black soil':degraded grassland is 17. 7%. It will be increased by overtaken and rodents pests. So some integration control methods should be made out.
