本文研究了在3个设置了人工循环系统的富营养化水库中蓝藻丰度与分层强度(N)的关系，以及设施规模对这种关系的影响。无论是否设置人工循环，当N > 10 [s]时，三个储层的蓝藻数量均显著增加。氮的减少需要一定的设施规模，设施对氮的充分减少发生在防止蓝藻的水库中。减少氮的适当设施规模被认为与每个油藏固有的内部弗劳德数有关。
We investigated the relationship between the abundance of cyanobacteria and stratification intensity (N) in three eutrophicated reservoirs in which an artificial circulation system had been installed and the effects of the facility scale on that relationship. Cyanobacteria markedly increased when N was above 10 [s] in all three reservoirs whether the artificial circulation was installed or not. A certain facility scale wais needed for the decrease of N. Sufficient decrease in N by the facility occurred in the reservoir in which cyanobacteria was prevented. The appropriate facility scale to decrease N was considered to be related to the internal Froude number inherent in each reservoir.
