太湖蓝藻暴发的气象条件研究

Study on the meteorological condition of blue-green algae fast growth in Lake Tai

通过对1986—2007年12个太湖蓝藻暴发典型个例的分析,得出:水体污染造成富营养化是蓝藻生长发育和暴发的基础,日平均气温偏高、降雨量和降雨日数偏少、气压偏低、日照时数偏多有利于蓝藻生长发育和暴发;水质、气象等要素的综合作用是蓝藻暴发的主要原因。

The 12 typical eases of blue-green algae fast growth in lake Tai in 1986-2007 have been analyzed. Combined with suitable meteorological conditions, such as： high mean daily temperature, long duration of sunshine, less amount of precipitation, shortage of rain-days and lower pressure of air, bluegreen algae growth is unavoidable to accelerate. In short, leading factor of blue-green algae fast growth in lake is integration effeet of water quality and weather.
