| 摘 要： | 试验研究了不同氮磷比对水体藻类生长以及对水环境因子的影响。通过设置水样的氮磷质量比(m(N)/m(P))分别为3、5、10、20、30、50,并对其进行长期连续观测,结果表明,当m(N)/m(P)为3.0～10.0时,有利于藻类的生长;m(N)/m(P)大于10.0时,将抑制藻类生长。在适合藻类生长的培养水体中,磷是限制藻类生长的主要因素。不同m(N)/m(P)对于藻类生长周期各个阶段出现的时间和持续时间影响效果不显著;藻类暴发前pH值与DO浓度都会出现峰值,据此可以建立藻类暴发预警系统。

| Abstract: | The impact of N/P ratio on algae growth and water environmental factors was studied.The water samples with N/P ratio(m(N)/m(P)) of 3,5,10,20,30 and 50 respectively were investigated through a long-term continuous observation.The results showed that,the algae growth was promoted when the m(N)/m(P) ranged from 3.0 to 10.0,and inhibited when it exceeded 10.0.In the water sample which adapt to algae growth,phosphorus was the main inhibiting factor.The effect of m(N)/m(P) on the starting time and lasting time of... |
