摘    要:藻源性湖泛在春季和夏季均有发生,但湖泛发生的完整过程在野外很难被追踪到.本文利用专利装置进行了春季与夏季藻源性湖泛的室内发生模拟,研究了湖泛发生过程中水体视觉和嗅觉两方面特征指标的变化过程.结果表明:湖泛在春季比夏季需要更长的酝酿时间方可发生,且持续时间较短;春季湖泛发生时水体真色度与悬浮固体含量均要高于夏季,且波动更显著;夏季湖泛致臭物质的变化较春季更明显,具有迅速、持久的特点;春季与夏季藻源性湖泛过程均具有嗅觉特征先于视觉效果显现的现象,即呈现先臭后黑的特点.

关 键 词:湖泛  季节差异  视觉特征  嗅觉特征  变化过程

Abstract:Algae-induce black bloom has occurred in the spring and summer, but the whole process of black bloom occurring was difficult to tracked in the wild. The study used a patented device simulation that the occurred process of algae-induce black bloom in spring and summer, and studied the change process of characteristics indicators of visual and olfactory when the black bloom occurred. The results showed that: spring black bloom occurred takes longer than in summer, and the short duration. True chromaticity and suspended solids of the black water in spring higher than in summer, and more intense volatile. The change process of the odor substances in summer black bloom more obvious than in spring, at the same time, the black bloom of summer was more quickly, more obvious, and more durable than spring. The algae-induced black bloom processes of spring and summer have shown black and odor appear not synchronized, olfactory effect manifested earlier than visual effects, that is olfactory effect appeared earlier than the visual effect.
Keywords:black bloom  seasonal differences  visual characteristics  olfactory characteristics  change process
