摘要
在三峡库区香溪河支流高岚河库湾修建了生物浮岛,并在浮岛周围及上下游设置点位监测理化指标和浮游藻类。结果发现高岚河水体处于中营养型-轻度富营养型水平。在8月期间,藻类大量生长,浮岛区理化指标Chla、DO、CODMn、低于对照区,NH4+-N、高于对照区。浮岛上植物去除TN负荷顺序为美人蕉﹥风车草﹥菖蒲﹥梭鱼草。去除TP负荷顺序为美人蕉﹥风车草﹥梭鱼草﹥菖蒲。在植物生长过程中,单位干重的TN含量逐渐降低,TP含量先增加后降低。在浮岛区和对照区发现藻类7门31属,4月藻类主要以绿藻、硅藻为主,8月主要以蓝藻为主。浮岛区和对照区藻类种群结构无明显差异。在8、9月,浮岛区藻类生物量明显低于对照区。蓝藻种群与CODMn呈正相关(r=0.6829)。藻类生物量及种群结构随时间变化显著(p<0.05)。
An artificial-floating island was built at a bay of the Gao Lan River which is a tributary of the Xiangxi River in the Three Gorges reservoir. Samples were collected from several sites around artificial-floating island, upstream and downstream the Gaolan River for the monitoring of physic-chemical parameters and phytoplankton. From the results we can conclude that the water is mild eutrophicated. When algae blooms in August, Chla, DO and CODMn of floating island area were lower than those of the control area while NH4+-N was higher. TN removal by the plants on the floating island was in the following order: Canna indica > Cyperus alternifolius > Pontederia cordata > Acorus calamus Linn while the TP removal was in the following order: Canna indica > Cyperus alternifolius > Acorus calamus Linn > Pontederia cordata. The N content of the plants decreased with the growth of the plants while the P content first increased then decreased.In the study areas, 31 algal genera of 7 phyla were identified. In April, bacillariophyta and chlorophyta were dominant while cyanophyta was dominant in August. CODMn is positively related to the cyanophyta density(r=0.6829). The density of algae in the floating island area is significantly different(p<0.05)from the control area in august and September.
