摘要
在新疆巴音布鲁克高寒草原对沼泽植物群落的结构、植物物种多样性和生产力的研究表明:高寒沼泽草地主要由水生植物和湿生植物构成,植物种类以莎草科较多。水沼泽植物群落的优势度指数大于丘状沼泽。植物群落物种重要性的大小依次为:黑穗苔草>细刺苔草>嵩草>囊状苔草>马先蒿>水麦冬>报春花。高寒沼泽草地的平均鲜草产量为571.5g/m2,平均载畜能力为1.69只羊单位/ha。水沼泽草地的鲜草产量高于丘状沼泽,分别为646.2g/m2和496.7g/m2。
Structure, plant species diversity and productivity of swamp community were studied in Bayanbulak alpine grassland, XinJiang. The results showed that alpine swamp grassland is composed of aquatic plants and wet ground plants, the number of plant species of cyperaeeae are more than others families. Simpson index of aquatic swamp is higher than mound swamp, important value decreased gradually in the order of Carex melanantha, Carex microglochn, Kobresia filifola, Carex vesicular, Pedieularis albevti, Triglochin plustre, Primula sibirica. Average productivity of wet grass of alpine swamp grassland is 571.5g/m^2, proper carrying capacity of alpine swamp grassland is 1.69 sheep unit/ha. Productivity of wet grass of aquatic swamp（646.2 g/m^2） is higher than mound swamp（496.7g/m^2）.
