摘    要:水位作为重要的湖泊水文因子,对湖泊水动力过程、化学过程和生态过程具有重要的影响。通过2007~2008年鄱阳湖湖口的水位、水环境实测数据,分析了湖口的水位及水体各环境因子的变化特征,阐述了各水环境因子对水位变化的响应关系,并建立了水位与各水环境因子的回归方程。结果表明:湖口的水位及各水环境因子均呈现季节性变化,湖口水位与长江(九江站)水位呈直线正相关;湖口的水位变化对其水体各环境因子均存在明显的影响,其中水体透明度随水位上升而增大,悬浮物、溶解氧、高锰酸盐指数、氮化物和磷化物浓度随水位上升而下降。

关 键 词:水位  水环境因子  相关分析  湖口  鄱阳湖

Abstract:Water level, an important hydrological factor in shallow lake, has great influence on hydrodynamics, ecological and chemical processes. Based on the field observations from 2007 to 2008, the seasonal change of water level and water environmental factors in Hukou area of Poyang Lake were analyzed. Meanwhile, the relation regression equations between water level and water environmental factors were established. The analysis demonstrated that all the parameters showed an obvious seasonal change. The relationship between water of Poyang Lake (Hukou Station) and that of Yangtze River (Jiujiang Station) was positive and linear. The changes in water level were found to have a significant influence on the water environmental factors in Hukou area of Poyang Lake. With increases of water level, the transparency increased accordingly, but the permanganate index and the concentrations of suspended matter, dissolved oxygen, nitride and phosphide declined accordingly.
Keywords:Water level  Water environmental factors  Correlation analysis  Hukou area  Poyang Lake
