中文摘要	利用冷季调查的牧草相关数据,以牧草保存率为主要参数,分析研究区域内草甸草原、典型草原、荒漠草原和沙地植被四种草地类型的牧草保存率的变化趋势.结果表明:四种草地类型在常年围封和自由放牧两种利用状态下的牧草保存率逐月递减,其递减趋势各不相同.常年围封状态下,冷季末期(4月)草甸草原、典型草原、荒漠草原和沙地植被牧草保存率分别降至41.7%、48.3%、39.0%和35.5%,平均月递减率分别为10.6%、10.3%、12.2%和12.9%;自由放牧状态下,冷季末期四种草地类型牧草保存率降至11.7%、12.6%、0和12.6%,牧草保存率平均月递减率分别为17.7%、17.5%、20.0%和17.5%.
英文摘要	Making use of the grass data investigated in cold season, taking grass preservation rate as the major parameter, the changing trend of grass preservation rates of meadow steppe, typical steppe, desert steppe and sand vegetation was analyzed.The results showed that the grass preservation rates of the four grasslands in fenced and free grazing were decreased month by month in normal year, the decline trend was different among four grasslands.The grass preservation rates of meadow steppe, typical steppe, desert steppe and sand vegetation in the late cold season (April) fenced whole year were 41.7%, 48.3%, 39.0% and 35.5% respectively, average month decrease rates were 10.6%, 10.3%, 12.2% and 12.9% respectively.The preservation rates of meadow steppe, typical steppe, desert steppe and sand vegetation in free grazing were 11.7%, 12.6%, 0 and 12.6% respectively in April, the average month decrease rates were 17.7%,17.5%,20.0% and 17.5%, respectively.
