Abstract:

水华鱼腥藻是常见的有害水华藻种,但其在磷、光强、温度等生境要素协同作用下的生长动力学鲜见报道.本研究在Lehman模型、Steele模型基础上,设置8个PO43--P梯度:0、0.1、0.2、0.5、0.75、1.0、2.5、5.0μmol/L,4个温度水平:15、20、25和30℃和4个光强水平:1000、2000、3000和5000lx,采取单因素实验方法进行水华鱼腥藻室内纯培养.Monod模型表明水华鱼腥藻最适生长温度和光强条件分别是20℃和3000lx,最大比生长速率(μmax)和半饱和常数(KS)分别为0.447d-1和0.081μmolP/L;分别用Lehman模型和Steele模型模拟水华鱼腥藻μmax在不同磷浓度下对连续变化的温度和光强的响应,Lehman动力学模拟结果表明水华鱼腥藻的最适生长温度为21.22±0.98℃,μmax和KS分别为0.421±0.011d-1和0.055±0.009μmolP/L;Steele模型结果表明μmax和KS分别为0.461±0.010d-1和0.051±0.009μmolP/L,水华鱼腥藻最适生长光强Ik为2650.93±88.19lx.
