摘要:
对太湖流域多个县(市)浮萍分布情况进行调查,观测各地浮萍种类及其生长水体的水质状况,探讨水体pH值,铵态氮、硝态氮、总氮、总磷含量及其与浮萍分布的关系。调查结果表明,浮萍适宜生长在静止的水体中,流动的河流中较为少见。太湖流域采集到3属5种浮萍,分别为Spirodela polyrrhiza、Lemna minor、Lemna turionifera、Lemna aequinoctialis、Landoltia punctata。其中,紫萍属(Spirodela genera)和青萍属(Lemna genera)分别占到49%和37%,为该地区主要的浮萍种类。少根紫萍适宜在中性的环境中生长,而紫萍适宜生长在偏碱性的水体中;相对而言,青萍生长的pH范围更广,在pH值 6.34~8.78均有分布。太湖流域浮萍生长水环境中氮、磷含量范围较广,铵态氮、硝态氮、总氮和总磷质量浓度范围分别为0.28~19.67、0.01~5.18、0.10~24.62、0.03~2.45 mg/L。尚未发现自然环境中浮萍的分布与水体氮、磷含量间的必然联系。调查还发现,太湖流域浮萍淀粉含量在10.95%~23.27%之间,均值为15.95%。在太湖流域水生植物修复过程中,可优先考虑利用当地优势浮萍品种及不同品种浮萍的共生复合系统,构建浮萍塘生态系统,来去除水体中的氮、磷等营养物质。
