摘要
以卫星遥感2002～2007年NOAA/AVHRR为信息源,统计这一时段内巢湖发生水华的资料,对水华的时空变化规律进行了分析.同时,结合相应的气象要素资料,对水华发生的气象条件进行分析.结果表明,巢湖水华的发生具有明显的时空规律,春、夏季多发,4,8月份的发生概率分别为19%和39%;西半湖多发,年均发生概率最大值均超过8%;气温、日照和风是影响巢湖水华的主要气象因子.
Remote sensing data of NOAA/AVHRR from 2002 to 2007 was used to analyze temporal and spatial characteristics of algae bloom. And then the meteorological condition was studied, and to find the key meteorological factor and interrelated parameter which can control the algal growth. The temporal and spatial variation of algae bloom were significant. During the spring and summer, it occurred frequently, and the maximum probability were 19% and 39%, respectively. In the western region of Chaohu Lake, the algae bloom occurred frequently and the probability was over 8%. Atmospheric temperature, sunlight and wind are the main meteorological factors those effected the algae bloom.
