摘 要：
2006年8—9月通过样方法,对安徽黟县、泾县2地记录有野生金头闭壳龟分布的34个栖息地进行了实地调查,分析了植被的改变对野生金头闭壳龟栖息地其它环境因子的影响。结果表明:对金头闭壳龟栖息地产生较大影响的环境因子包括植物群落结构、溪边沙地、溪流水体环境等;野生金头闭壳龟栖息地植被多是天然林砍伐后形成的次生林、人工毛竹林和杉木林;统计样方中共有维管植物443种,分属129科232属,其中,河柳、枫杨、毛竹、水杨梅、鬼针草、线穗苔草、水蓼等植物在样方中出现频度较高(>50%)。植被的改变对金头闭壳龟生存繁殖产生很大影响,是导致金头闭壳龟濒危的主要原因之一。

摘 要：
In August-September 2006,a field investigation was made on the vegetation and other environmental factors in 34 wild Cuora aurocapitata habitats in Yixian and Jingxian counties of Anhui Province to study the effects of vegetation change on the other environment factors of wild C.aurocapitata habitats.It was found that the main environmental factors affecting the wild C.aurocapitata to select its habitats were plant community features,sandlot,and swag,etc.The vegetations of wild C.aurocapitata were mainly secondary deciduous broadleaved forest,Phyllostachys edulis forest,and Cunninghamia lanceolata forest.In all investigated sites,there were 443 species of vascular plants belonging to 129 families and 232 genera,and the high frequency plants were Salix chaenomeloides,Pterocarya stenoptera,Phyllostchys pubeseens,Adina rubella,Bidens bipinnata,Carex nemosttachys,and Polygonum hydropiper.Vegetation change significantly affected the survival and reproduction of wild C.aurocapitata,being one of the main causes made C.aurocapitata nearly endangered.
