摘　　要：研究结果表明,藻类种群数量一直较大,经常发生赤潮的藻类,种群会不稳定,藻类种群会发生衰退概率增大;藻类种群数量一直较小的藻类,偶尔发生赤潮,也会发生种群衰退概率增大。赤潮是藻类种群大量繁殖的结果,而经常发生赤潮又使藻类种群衰退概率增大,繁殖和衰退是矛盾的统一体,因此种群的更替是赤潮普遍的现象。The exponential growth,population size and natural growth rate of algae population can produce random disturbances and have an impact on the population stability of algae.In this paper,from the mathematical ecology perspective,and qualitative description,algae have a large population of red tide algae,and the populations will become unstable,algae populations increasing the probability of decaying.The algal populations have been smaller algae,and the occasional red tide can also increase the probability that the populations fall.The red tide algae result from a large number of breeding populations of algae,the frequent arising of red tide algae makes algae populations increase in the probability of decaying,reproduction and the decay is the identity of the opposites,and thus species turnover is a common phenomenon of red tide.
