蓝藻水华暴发是在一定的营养、气候、水文条件和生态环境下形成的藻类过度繁殖和聚集的现象,是水体环境因子(如总氮、总磷、pH值、溶解氧)和气象因子综合作用的结果. 然而滇池周年性水华暴发标志着滇池蓝藻水华在当前水质条件下,气象因子为关键影响因子. 为了进一步探究滇池蓝藻水华发生与气象因子的规律,本文利用2010-2011年滇池蓝藻水华遥感监测资料与周边地面气象站逐月资料,研究滇池蓝藻水华月发生频率与月气象因子的关系. 结果显示,滇池蓝藻水华发生频率与平均气温、最低气温、平均风速、累计日照时数和降雨量等气象因子均表现为显著相关,其中与日照时数和风速呈显著负相关. 各因子中与风速...

The published study suggested that cyanobacteria bloom was a phenomenon of excessive reproduction and aggregation with certain nutrient levels, climate and hydrological conditions and was the result of the comprehensive effect of meteorological and water environmental factors such as total nitrogen, total phosphorus, pH values. It was also found that annual outbreak of cyanobacteria bloom in Lake Dianchi indicated that, under the current condition of water quality, the main factor was the meteorological factor. In order to further explore the regularity between meteorological factors and occur...
