摘要
滴水湖是在围垦滩涂上开挖的人工湖泊,2003年10月开始引水。为了对滴水湖引水成湖后早期的湖泊生态状况进行评价,本文测定了2008年3月至2009年2月滴水湖周年的水质状况。结果显示:湖泊透明度年平均值为(40.7±8.3)cm,溶解氧DO年平均值为(10.09±2.32)mg/L,总氮TN年平均值为(2.765±0.629)mg/L,总磷TP年平均值(0.336±0.108)mg/L。综合比较发现,滴水湖全年处于中富营养化水平状态。本文结合当地实际情况给出了切实可行的治理建议。
Man-made Dishui Lake which is excavated in the reclamation of beach land began to be perfused in Mar.2003.To assess its earlier ecological condition,this study analysis monthly data samples from the lake between Mar.2008 and Feb.2009 to investigate the changes in water quality,and evaluate the nutrition level of the water body.The results are followed by average transparency of year（40.7 ± 8.3） cm,DO（10.09 ± 2.32） mg/L,TN（2.765 ± 0.629） mg/L,and TP（0.336 ± 0.108） mg/L.Compared with the data earlier years’,the lake is in the condition of medium eutrophication comprehensively.And some practical and rational proposals were given.
