研究于 2008 年 12 月至 2009 年 10 月按季度对大通湖水质及软体动物资源监测,并通过纵向比较,探讨了集约化养殖对大通湖水域环境及软体动物群落的影响,以期为其渔业可持续发展提供理论依据.结果显示,大通湖水质全年呈碱性 (8.62 ± 0.07),具有较高的还原性 [(-88.40 ± 9.10) mv],属富营养水体.软体动物共计 5 科 15 种,梨形环棱螺(Bellamya purificata)、河蚬(Corbicula fluminea)和圆顶珠蚌(Uniodoug lasiae)是主要优势种.软体动物平均密度和生物量具有明显的时空差异,时间上呈现由春夏季到秋冬季逐渐升高的趋势,空间上整体呈现由东北向西南逐渐递减的趋势.典范对应分析表明氧化还原电位、p...

The environmental characteristics and Mollusca community in Datong Lake were investigated seasonally from December 2008 to October 2009.Potential effects of intensive aquaculture on water quality and Mollusca in Da-tong Lake were studied by comparing the current sampling with the historical data in 1960,to provide theoretical sup-port for sustainable fishery of the freshwater lakes.The results showed that Datong Lake was eutrophic and the water was alkaline(8.62 ± 0.07),with higher reducibility(?88.40 ± 9.10 mv).Fifteen Mollusca species were ...
