梁子湖水生植被

AQUATIC VEGETATION IN LIANGZI LAKE

对梁子湖水生植被的种群组成、植被类型和生物量进行了初步调查。结果表明：梁子湖水生高等植物的种类为３５科６２属９２种，全湖沉水植物平均生物量为４．７５ｋｇ·ｍ^（－２）。根据梁子湖水生植物的种类组成和结构全湖分为１２个水生植物群落。梁子湖水生植被带状分布不显著，其特点是挺水植物和漂水植物未形成一个独立的植物带，沉水植物占绝对优势，分布面积接近全湖。

This paper reports aninvestigation on the species composition,vegctation type and biomass of aquatic vegetation in Liangzi lake.The resalts show that there are about 92 species of vascular plants belonging to 62 genera and 35 families.The average biomass of submersed plants of whole lake is 4.75 kg·m-2 According to species composition and constitution,the vegetation of Liangzi lake can be classified into 12 aquatic vegetation types of communities. The zonal distribution of aquatic vegetation in Liangzi lake is unapparent.Its outstanding feature is that the emergent and floating plants does ont form an independent zone of vegetation.The absotute dominant is the submersed plant species and distributes in almost whole lake.
