摘要:

根据2008年4~11月无锡市环境监测中心站对梅梁湖水域的应急监测数据,探讨了夏季梅梁湖水体中蓝绿藻密度和叶绿素的时空分布特征。结果表明,蓝绿藻密度和叶绿素均存在明显的时空变化;月变化中,蓝绿藻密度和叶绿素分别在9月份和8月份达到最高值,可见影响梅梁湖藻类大量繁殖的主要环境因子是水温;空间分布中,蓝绿藻密度和叶绿素均在北岸为最高,沙渚水域的蓝绿藻密度和叶绿素较低,这可能主要与太湖夏季盛行“东南风”和“引江济太”的调水工程有关。可见梅梁湖藻类大量繁殖的8、9月份是需要重点关注的月份,同时相对于梅梁湖其他水域,把沙渚作为无锡重要饮用水源地是非常合理和正确的选择

Abstract:

Temporal and spatial distributions of bluegreen algae density and Chlorophyll were discussed according to emergency monitoring data of the Meiliang Lake measured by Wuxi environmental monitoring centre with Multiparameter Water Quality Sonde YSI6600v2 in 2008 from April to November.Data indicated that obvious temporal and spatial variations were found for bluegreen algae density and chlorophyll.Bluegreen algae density and Chlorophyll reached the highest value in September and August respectively,and reached the highest in the north zone of the lake,and the lowest in the Shazhu zone.The results showed that water temperature was a major limiting factor for the algae growth in summer Meiliang Lake,and the spatial distribution of algae was greatly influenced by the “southeast wind” and “The project of water diversion from the Yangtze River to Taihu Lake”.It was easy to see that the focus of attention was needed in the algal blooms of Augst and September in Meiliang Lake,and the Shazhu as an important drinking water sources compared with other zones in Meiliang Lake was very reasonable and the right choice.〖
