  • 摘要: 选取长潭水库为研究对象,进行水环境因子和浮游植物群落特征分析,探讨水体氮、磷营养盐时空分布特征,阐明流域土地利用类型变化对水质影响以及驱动浮游植物群落季节性变化的主要环境因子,并根据主要环境问题提出针对性建议。结果表明:耕地和林地面源污染是水体总磷(TP)的主要来源,在水库蓄水区总氮(TN)、TP滞留率分别为41.71%和51.17%,由此形成库区氮磷比(N/P)为34.5的磷限制型水体,导致蓝藻生长更具优势;蓝藻各季节丰度占比为33.72%~82.47%,优势度大于0.02的浮游植物物种以蓝藻为主,其中产毒藻拉氏拟柱孢藻优势度最大(Y=0.078);冗余(RDA)分析结果显示,环境因子解释了群落结构演替的61.1%,其中水温和氮、磷营养盐浓度是驱动演替的主要环境因子;水体氨氮( NH 4 + -N)浓度与拉氏拟柱孢藻丰度呈极显著相关(R2=0.999,P<0.02),将流域生活污水处理率提高至95%,且 NH 4 + -N排放浓度不大于1.5 mg/L时,预期可减少51%拉氏拟柱孢藻丰度。提出建设面源污染隔离带、调节缩短库区水力停留时间以降低蓝藻生长优势、改善长潭水库水生态状况的主要措施对策。
