太湖蓝藻水华预警监测与风速风向的关系研究

Study on Correlation between Data for Cyanobacteria Bloom Early Warning Monitoring and for Wind Speed and Direction in Taihu Lake

太湖蓝藻水华预警监测的启动问题已基本解决,但监测响应日期和周期却一直难以确定。统计分析了太湖2007—2009年蓝藻预警监测、现场观测的历史资料,研究蓝藻水华在水体中的分布与风速风向之间的关联规律,从环境监测部门蓝藻预警监测工作的实际出发,划分出了蓝藻水华预警监测的响应级别,提出具体的监测要求,较好地解决了预警监测的响应周期问题。为环太湖地区相关部门更好地开展蓝藻预警监测工作提供了科学依据。

The mechanism for Cyanobacteria bloom early warning monitoring in Taihu Lake was initially established. However, determination of the response date and cycle has yet to be addressed. The history data for early warning monitoring and field observations of cyanobaeteria bloom in Taihu Lake from year 2007 - 2009 was summarized and the correlation between the distributions of cyanobaeteria bloom and wind speeds and directions was explored. Different response levels were defined based on the monitoring requirements, a solid ground for relevant departments to carry out early warning monitoring of cyanobaeteria bloom in Taihu Lake area.
