摘要
采煤塌陷区人工湿地含有氮、磷、重金属等污染物,适宜采用水生植物进行生态修复。通过调查分析,发现九里湖人工湿地含有芦苇、菖蒲等挺水植物,水鳖等浮叶根生植物,金鱼藻、马来眼子菜、菹草等沉水植物。水生植物通过吸附、吸收等净化作用,有效降低了九里湖水体悬浮物的浓度、水的浊度,增加了水体的透明度、溶解氧,有效抑制了藻类生长。
There is plenty of nitrogen, phosphorus and heavy metal pollutants in artificial wetland in the subsided coal-mining areas, aquatic plants are the best choice to restore the site. Through investigation and analysis, it was found that emergent plants of Phragmites australis and Acorus calamus, floating-leaved plants of Hydrocharis dubia, and submerged plants of Ceratophyllum demersum, Potamogeton malaianus, Potamogeton crispus growing in Jiuli artificial wetland. The aquatic plants in Jiuli lake purified the water through adsorption and absorption, effectively reducing the concentration of suspended matters and the turbidity of watel, increasing the transparency and dissolved oxygen of water, and theretbre effectively inhabiting the growth of algae
