摘  要:
在富营养水体云龙湖水库建立小型围隔进行沉水植物恢复试验。结果表明,沉水植物在围隔中的恢复效果主要与沉水植物种类、形态特征、生理特点和水体状况有关,在移栽的4种沉水植物中,金鱼藻生物量增长最快,8月收割时达到5.96 kg.m-2,为种植时的29.8倍,马来眼子菜、狐尾藻和苦草的生物量分别为2.16 kg.m-2、1.44 kg.m-2和1.12 kg.m-2。

摘  要:
The recovery experiments of submerged plants were done by utilizing the small enclosures in the eutrophic water of Yunlonghu Reservoir in this study.The result showed that the effect of recovery was mainly related to species,the morphological and physiological characteristics of submerged plants and the water quality.Among four chosen transplanted submerged plants,Ceratophyllum demersum L.grew fastest,reached 5.96 kg·m-2 when it was harvested in August,29.8 times as much as its original biomass,the biomass of Potamogeton malaianus Miq.,Myriophyllum spicatum L.and Vallisneria spiralis L.was 2.16 kg·m-2,1.44 kg·m-2 and 1.12 kg·m-2,respectively.
