摘    要:通过对千岛湖网箱养殖区内外水域的四季水质调查,分析得出网箱养殖对千岛湖局部水域会产生明显的影响。造成养殖区水域的DO、pH下降,TN升高,不同季节和不同的水层影响存在差别。冬季对浅层的DO、pH产生明显下降,影响区域小;春季对表层的DO、pH产生明显下降,影响区域大;夏季受水温分层,影响不明显;秋季造成各层水体DO、pH下降,TN上升,影响区域大。千岛湖网箱养殖在春季和秋季对养殖区局部水域影响明显,但分散的网箱养殖对水域影响范围较小,对千岛湖水体短期内影响不明显。

关 键 词:千岛湖  网箱养殖  理化因子

Abstract:According to the seasonal water quality investigations and the analysis of fish cage - farming in Qiandao Lake, it is found that fish cage -farming will have an obvious impact on the partial waters of Qiandao lake, which causes the decline of DO and pH and the rise of TN in the waters of fishpond areas. However, the effect on waters differs from different seasons and different water levels. In winter, DO and pH in shallow layer in small area drops obviously ; In spring, DO and pH in surface layer drops obviously in large regional ; In summer, because of the water temperature lamination, the effect is not distinct; In autumn, it makes various laminations water body DO and pH fall, while TN rises in large regional. The scattered fish cage -farming in qiaodao lake have an obvious impact on the waters in spring and autumn. However, it just affects the smaller area and will not make a significant impact on the water body of Qiandao lake in a short term as a whole.
Keywords:Qiandao lake  Cage culture  Physical and chemical factors
