摘要
青藏高原高寒草甸退化草地有1620×104hm2,占全区退化草地面积的32.40%。退化草地生产力很低,水土流失严重。由于长期超载过牧、鼠类危害和气候变暖等影响,加快了高寒草甸的退化速度。因此,对退化的高寒草甸类草地进行综合治理的探讨势在必行,针对退化原因,提出了以草定畜、防治草原鼠害和建立人工草地等治理对策。
There 1620×10~4km^2,degraded alpine meadow in Qingzangplateau,occupied 16.54%the all area of degraded grassland,low grassland productivity,water and soil run off seriously,degradating of alpine meadow is speeded up since overgrazing for long time and the hazardous of mouses etc...Hence,investigating of strategy to manage the grassland is necessary.According to the degradation reason of the type grassland,the paper propounded strategy to restrict grazing capacity and establish artificial grassland etc...
