| 摘 要： | 2008年3月至2009年9月对紫阳湖生态修复效应进行了全程跟踪监测及诊断指示研究。研究表明,通过水生生物群落构建,水生态环境有了明显改善,全湖水质达到地表水IV标准,透明度上升到100 cm左右,叶绿素a下降到10 mg/m3以下。生态修复后各指标50%的效应时间序列为Chla、DO、SD、TP、NH3-N、TN和COD。研究认为,Chla/SD作为湖泊水质指数(LQI)是检验生态修复效果较敏感的指标,可用于浅水富营养湖泊生态修复后水质的诊断和评价。

| Abstract: | From March 2008 to Sept.2009,effects of ecological restoration in Ziyang Lake were studied.Results showed that water quality has improved significantly,with transparency increasing to 100cm and Chla decreasing below 10mg/m3.Time series of 50% effect of parameters are Chla,DO,SD,TP,NH3-N,TN and COD.Chla/SD,as lake water quality index(LQI) is the most sensitive indicator used for diagnosis and evaluation of water quality after ecological restoration in shallow eutrophic lakes. |
