摘要
江西省地处长江中下游交接处的南岸,境内有大小河流2400多条,总长约18400km。江西河流水生植被的组成植物隶属27科,36属,共61种,且可划分为14个主要群落类型,其中以苦草、黑藻、竹叶眼子菜、(艽木)和菹草、微齿眼子菜、金鱼藻等沉水植物群落分布较广,面积较大;而适应流水和水深变化能力较差的挺水、浮叶及漂浮植物仅零星分布在河流边岸、河湾水潭边缘或河滩低洼处等。
There are more than 2400 rivers with a total length of 18400km in Jiangxi, a province south to the middle and lower reaches of the Changjiang (Yangtze) River. Sixty one species of aquatic plants belonging to 36 genera of 27 families are identified in the rivers in this province. Vegetation in the rivers Jiangxi can be classified into 14 major types of communities. The submersed plants, including Vallisneria spiralis, Hydrilla verticillata, Potamogeton malaianus, Muriophyllum spicatum+Potamogeton crispus, Potamogeton maackianus, Ceratophyllum demersum ect., are adapted to living in flowing, deep waters and have wide distributions. The emergent, floating-leaved and freely-floaing plants are secttered near the river-sides because of their relative poor adaptations to flowing, deep waters.
