小型人工湖蓝藻水华季节性发生规律及其防治研究

以西安鱼化湖为研究对象,通过原位观测总结了鱼化湖季节性蓝藻发生的现象和规律,表明蓝藻水华的发生季节与水质富营养化程度密切相关,人工湖蓝藻水华产生的原因主要可归纳为外源因素和内源因素。在蓝藻水华现象和原因分析的基础上针对鱼化湖具体特点提出了蓝藻的治理方法,所得结论与建议可为以后人工湖蓝藻预防与治理提供借鉴。

Seasonal Occurrence Regularity of Cyanobacteria and its and Control in Artificial Lake in Xi'an

Cyanobacteria control is still a major water environment problem which has not been solved in our country.Especially in the northwest region,there are less related research about cyanobacteria control in artificial lakes.In this paper we choose Yuhua lake as the main research object,the causes of artificial lake cyanobacteria blooms is analyzed,the seasonal occurrence regularity and control methods in the international university to reveal seasonal regulation of cyanobacteria in Yuhua lake in theory.We also find a scientific method to deal with cyanobacteria in artificial lake and restore a healthy lake ecological system.Finally,to prevent cyanobacteria disasters happened in xi'an artificial lakes in the future and provide a feasibility reference on prevention and control technology for cyanobacteria in artificial lakes in the northwest region.
