摘　　要：选取黑藻、苦草、金鱼藻、狐尾藻4种沉水植物作为试验对象,模拟墨水湖水体环境开展沉水植物种植技术研究,并在户外静水条件下对不同植物的净化能力和耐污能力进行综合比较,结果表明:4种沉水植物对水体中TN、TP、NH_(3)-N、COD_(Mn)的去除效果均优于对照组,各污染指标的实际去除率范围为43.28%~58.95%、65.36%~66.38%、52.63%~54.26%和36.59%~45.08%,且黑藻的株高和生物量变化均高于其余3种植株增长量,其耐污能力优于其余3种。4种沉水植物对水体治理能力大小为:黑藻>苦草>金鱼藻>狐尾藻。与此同时,还需开展植株种植后期对湖泊水体负面影响的研究,运维管理亦是沉水植物种植关注的重要环节。Four submerged plants were selected as the test objects,and the submerged plant planting technology was studied in the simulated ink Lake water environment,and the purification capacity and pollution resistance capacity of different plants were comprehensively compared under outdoor conditions.The results showed that:The removal effects of the four submerged plants on TN,TP,NH_(3)-N and COD_(Mn)in water were all better than those of the control group.The actual removal rates of each pollution index ranged from 43.28%to 58.95%,65.36%to 66.38%,52.63%to 54.26%and 36.59%to 45.08%.The changes of plant height and biomass were higher than those of the other three plants,and its pollution tolerance was better than that of the other three plants.The water treatment capacity of the four submerged plants was as follows:black algae>bitter grass>goldfish>foxtail.At the same time,it is also necessary to carry out research on the negative effects of plant planting on lake water body in the later stage,and operation and maintenance management is also an important link of submerged plant planting.
