摘要

近年来，我国重要湖库水源的蓝藻水华现象日趋严重，由此产生的有害藻类代谢物质(嗅味物质、 藻毒素等)严重威胁饮用水安全。本项目选择我国北方营养程度有显著差异的湖库型水源地(密云水 库和洋河水库)为研究对象，围绕蓝藻水华及有害次生产物的暴发，通过原位观测和微宇宙模拟实 验，系统研究蓝藻水华对营养状态和水力条件的响应机制，以及嗅味物质和藻毒素产生的物理、化学 及生物学机制，综合应用生态水力学、环境化学和分子生物学方法，建立环境因子与藻类种群及其次 生产物变化之间的定性与定量模式，构建藻类生态动力学模型,对水库蓝藻水华暴发及有害次生产物 的产生行为进行预测，为湖库型水源地管理及水质安全保障提供科学基础。
