摘  要:
通过对1978~2007年30年间洪泽湖蓝藻暴发的18个案例分析,结果表明,洪泽湖蓝藻产生和暴发的主要气象条件为月平均气温异常偏高、旬降水量偏少和旬日照时数偏多。对上述气象条件历年值进行0、1因子选取,符合洪泽湖蓝藻暴发条件的为1,反之为0;旬内有蓝藻暴发的为1,反之为0;应用多因子交叉相关综合法建立洪泽湖蓝藻暴发预报方程,历史拟合率为87.5%,2008~2009年试报准确率87.5%。除气象条件外,洪泽湖蓝藻暴发还受工业污染等影响,在预报服务时要加以考虑。

摘  要:
Based on the data of 18 cases during the past 30 years from 1978 to 2007,the major meteorological conditions for blue-green alga fast growth in Hongze Lake were analyzed.The results showed that the conditions were as following:the monthly average temperature anomaly is on the high side,the ten days precipitation is lesser and the ten days sunshine hours is more than the normal.Through the 1(satisfied)or 0(non satisfied)factor selection for the above three weather conditions over the 30 years,the prognostic equations for blue-green alga outbreak are established by using multi-factors overlapping correlating synthesis method.The historical fitting rate was 87.5% and the experimental forecasting accuracy rate in 2008-2009 was 87.5% too.Beside the meteorological conditions,the blue-green alga is also influenced by industrial pollutions etc.,which have to be considered in the forecasting procedures.
