摘要
若尔盖高原湿地在青藏高原湿地生物多样性保护中占有十分重要的地位 ,但其现状不清。卫星影像解译表明若尔盖高原湿地面积为 3 .94× 10 4 hm2 ,占土地总面积的 2 .2 %。在各种湿地中沼泽所占的比重最大。与 2 0世纪 5 0年代和 80年代初期相比 ,湿地面积大幅度减小而且退化严重 ,急需保护。目前应采取的保护措施有 :加强湿地自然保护区的建设与管理 ;探讨湿地退化机制与生态恢复措施 ;进行沼泽湿地草场生态牧业试验和示范研究 ;加强湿地保护立法与宣传教育。
Wetlands in the Zoige plateau play an important role in the protection of the wetland biodiversity of the Qinghai and Tibet plateau, but their present situation is unknown. TM image shows that there is 3.94×10 4 hm 2 wetland in the Zoige plateau, accounting for 2.2% of the total area. The ratio of marsh is the most in all kinds of wetlands. Compared with the wetland area in the early part of 1950s and 1980s, that in the region at present decreased rapidly and degraded badly, and the wetlands in the region are in dire need of protecting. At present, the protecting measures include: (1) strengthening the construction and administration of wetland natural reserved area; (2) discussing degradation mechanism and ecological restoration measures; (3) carrying through ecological stock raising experimentation on wetland meadow; (4) enhancing lawmaking and education on wetland protection.
