兴庆湖景观水体复合生态修复实验研究

Experiment on composite ecological restoration of landscape water in Xingqing lake

以西安市兴庆湖景观水体为研究对象,进行复合生态修复实验研究。分别构建两组复合生态系统:系统1(伊乐藻+罗氏轮叶黑藻+睡莲+鲤鱼)和系统2(伊乐藻+罗氏轮叶黑藻+睡莲+鲫鱼)。研究表明:在相同的环境条件下,系统1对TN、TP、氨氮、高锰酸盐的去除率分别可以达到63.2%、97.2%、40%、15.6%;系统2对TN、TP、氨氮、高锰酸盐的去除率分别可以达到50.8%、78.5%、41.2%、16.5%;系统1比系统2的净化效果好,更适于兴庆湖景观水体的生态修复。

This paper was concerned with the composite ecological restoration experiment research on the landscape water body in Xi＇an Xingqing lake . Two groups of composite ecological system were constructed. The first system consists of waterweed , roche vane black algal , water lily and carp ; and the second system consists of waterweed , roche vane black algal , water lily and crucian carp. The research indicates that, in the same experimental condition, the removal rate of TN, TP, ammonia nitrogen, potassium permanganate in the first system can reach 63.2% , 97.2% , 40% and 15.6% respectively ; the removal rate of TN, TP, ammonia nitrogen, potassium permanganate in the second system can reach 50. 8%, 78.5%, 41.2% and 16.5% respectively ; The purification effect of the first system is better than that of the second system, and the first system is more suitable for ecological restoration of landscape water body in XingQing lake.
