摘    要:2011年7月和10月对汉阳“六湖连通”工程的5个湖泊(后官湖、三角湖、南太子湖、墨水湖和龙阳湖)沉积物磷含量进行调查,研究其表层沉积物磷含量的空间分布和季节差异,以了解汉阳湖群的沉积物污染特征,为湖泊污染控制和生态修复提供依据.结果表明,后官湖沉积物磷含量最低,为(0.20±0.03) g/kg,龙阳湖最高,为(0.64±0.11) g/kg,二者差异显著(P<0.05),三角湖、南太子湖和墨水湖沉积物磷含量差异不显著(P>0.05).除后官湖外,汉阳湖群沉积物磷含量季节差异不显著(P>0.05).汉阳湖群沉积物磷含量具明显的空间分布特征,这种分布格局主要受外源污染输入的影响.相关分析表明,沉积物全磷与水体总氮、总磷和电导率呈极显著正相关(P<0.01),与水体透明度呈极显著负相关(P<0.01).

关 键 词:汉阳湖群  沉积物    空间分布  季节差异

Abstract:Research on spatial distribution and seasonal difference of phosphorous contents in the surface sediments Hanyang Lakes including Lake Houguan, Lake Sanjiao, Lake Nantaizi, Lake Moshui and Lake Longyang in July and October, 2011 aimed at understanding pollution characteristic of the lake sediments and providing reference for pollution control and ecological restoration. It is concluded that: 1.The sediment phosphorous contents were the lowest(0.20±0.03g·kg-1) in Lake Houguan, and highest(0.64±0.11g·kg-1) in Lake Longyang. 2.Significant difference of phosphorous contents was shown between Lake Houguan and Lake Longyang(P<0.05), and not among Lake Sanjiao, Lake Nantaizi and Lake Moshui(P>0.05). 3.Seasonal difference of phosphorous contents for most Hanyang Lakes was insignificant except Lake Houguan(P<0.05). 4.Clear spatial distribution patterns of sediment phosphorous mainly caused by exogenous pollution were observed in Hanyang Lakes. 5.Correlation analysis indicated that total phosphorous of sediments had significant positive correlation with total nitrogen, total phosphorous, and conductivity of water(P<0.01), and significant negative correlation with water transparency(P<0.01).
Keywords:Hanyang  Lakes  spatial distribution  seasonal difference  phosphorous  sediment
