摘要:

湖南茶陵湖里沼泽(北纬26°50'、东经113°40')为一山地沼泽,面积0.15平方公里,海拔150米。对该沼泽的生境及水生植物进行了考察。采集到维管植物62种,其中,普通野稻(Oryza rufipogon)、长喙毛莨泽泻(Ranalisma rostrata)等为珍稀、濒危植物,总种数和珍稀、濒危植物种数多于我国大部分湖泊、沼泽。物种多样性程度之高与其水生生境的复杂性与稳定性有关。建议对这些珍稀、濒危水生植物及其生境采取保护措施。

Abstract:

In Chaling County, Huna Province, Huli Marsh (26°50' N、113°40' E, 150m above sea level)was investigated.It is surrounded with hills and covers about 0. 15km2. 62 species of aquatic vascular plants were collected inthis marsh. Of which, more than 2 species are rare or endangered plants, they are: Oryza rufipogon,Ranalisma rostrata, etc. The total species or the rare and endangered apecies are more than those of the mostmembers of the marshs or lakes in China, which related to the complexity and stability of the habitat.Authors suggest that these rare or endangered plants and their habitat should be conserved.
