摘要

1992~1993年对武汉东湖三个主要湖区(郭郑湖、汤林湖和牛巢湖)水生植被的调查表明,该湖区共有水生植物32种,优势种为大茨藻、狐尾藻、苦草和菱。金鱼藻呈不断扩大的趋势。植被类型可分为11个群丛,植被面积约为0.65km,总生物量为1236.39t(湿重),植被带状分布仅见于汤林湖北部和其他部分湖汊。汤林湖和牛巢湖水生植被正处于自然恢复演替阶段。

Abstract

The results obtained from investigation on the aquatic vegetation of three main subregions of East Lake (Guozhenghu, Tanglinhu and Niucaohu ) of Wuhan, in 1992 -- 1993 are presented. There were 32 species of plants, among them the dominant of community was Myriophyllum spictum, Najas marina, Vallisneria  natans and Trapa natans. The types of aquatic vegetation can divided into 11 associations, the areas covered by plants was about 0. 65 km2 and the biomass in total 1 236. 39 t (wet weight). The distribution of vegetation appears zonaly only mainly in the north of Tanglin lake subregion and other parts of lake bends. The aquatic vegetation in the subregions of Tanglin lake and Niucao lake is now in the natural succession stage. And, the approach to'the restoration of vegetation in East Lake is also discussed.
