利用沉水植物生长期收割进行富营养化水体生态管理的实地研究
Field study on effect of harvesting submerged plant during growing season for ecological management of eutrophicated water
摘要
Abstract
Experiment of harvesting submerged plant as a method of ecological management was conducted at Yulinglong in the Yuanmingyuan Park where surface water was supplied with reclaimed water. Water quality was monitored semimonthly from April to December, 2011. Results showed that the average concentrations of TP, SRP, TN, NH4+-N, NO3--N and COD were around 0. 1, 0. 04, 0. 86, 0. 1, 0. 32 and 18 mg/L, respectively as a result of harvesting submerged plants during growing season, and the water quality was thus maintained between Grade Ⅲ and Grade Ⅳ Two control areas were selected. Control 1 was located at Yulinglong inlet where no harvesting was conducted, and the highest concentrations of TP, SRP, TN and NH4+ -N were recorded as 0.5,0. 1,2.4 and 0. 60 mg/L, respectively, when submerged plants started decaying in September. A-quatic plants in Control 2 were mainly emerged ones, and the water quality was pervasively worse than that of Yulinglong, and the highest concentrations of TP, SRP, TN and NH4+-N reached 1. 2 , 0. 6, 6. 1 and 0. 61 mg/ L, respectively. The field experiment in Yuanmingyuan Park showed that submerged plants have strong capability of water purification, which can be enhanced through harvesting during growing season. Therefore, harvesting submerged plants during growing season can be applied as an effective measure for ecological management of eutrophicated water.关键词
