摘要
岳西妙道山高山沼泽植被生于海拔1 000 m左右的山谷林下,总面积1.4 hm2。群落共有维管束植物90科180属258种,含种类较多的科有蓼科、蝶形花科、蔷薇科、莎草科、菊科、禾本科等,林下以湿生草本为主,多成片分布,形成高山草甸。叶级为中等叶,生活型有地上芽植物、地面芽植物和水生植物,分为乔木层、灌木层、草本层及层间植物。物种多样性草本层>灌木层。妙道山高山沼泽植被研究价值高,应加强宣传和保护。
The alt wetland vegetation grown under the valley forest with 1.4 hm^2 total area in Miaodao mountains of Yuexi county was investigated. The result indicates there are vascular plants of 90 families, 180 genera,258 species with the predominance of Polygonaceae, Fabeaceae, Rosaceae, Cyperaceae, Compositae and Gramineae. The vegetation under forest is alt wetland with wet grass component of patch distribution. The living form of community with middling leaf grade is composed of supraterraneous bud, ground bud and hydrophyte.
