Research on purification efficiency of polluted water remediation by submerged macrophytes 沉水植物修复受污水体净化效能的研究
Rooted hydrophytes , both emergent and submergent , are found in this zone 该区域分布有有根的水生植物,包括浮游植物和沉水植物。
At present the submersed macrophytes in the lake are almost absent but floating plant 现在该湖沉水植物消失,菱等浮叶植物却泛滥成灾。
4 . furthermore , the purify functions in water with the submerged aquatic plants were realized 实验证明,沉水植物能有效地改善水体的水质及观赏效果。
Experimental study on improving ecological conditions through harvesting submerged plants in a vegetation rich lake 草型湖泊沉水植物收割工程对生态改善的试验
Therefore , establishing and restoring the ecosystem mainly of macrophyte was the effective way to control the eutrophication of the west lake 因此,建立和恢复以沉水植物为主的生态系统,是治理西湖富营养化的有效途径。
But it was rarely studied on the effects dependant on the low exposure concentration and the chronic toxicity to antioxidant enzymes 目前国内外对重金属的植物修复方面的研究重点是陆生和挺水超积累植物,对沉水植物的作用很少研究。
Considering the status of ignoring aquatic seeds in water scenery designing and utilization , we suggested it is necessary to use aquatic seeds in further designs . 5 但目前在园林水景中对沉水植物的应用考虑较少,为此,在以后的水景营造中应重视沉水植物的应用。
In this study the main form of the nitrogen that diffused from sediment into overly water was ammonia , and the submerged plant decreased the diffusion fluxes of ammonia and nitrate at water - sediment interface 总之,水沉积物界面氨氮是沉积物向上覆水扩散的主要氮组分,沉水植物降低了氨氮和硝态氮的扩散通量。
There were 119 species of wetland plants belonging to 82 genera and 44 families in yulin . 32 species were hygrophyte plants , 8 species were submersed plants , 11 species were floating plants , and 68 species were emergent plants 玉林湿地植物有44科82属119种,其中湿生植物32种,沉水植物8种,浮水植物11种,挺水植物68种。
