摘    要:环境一号卫星CCD数据具有获取周期短、空间分辨率高等特点,能够及时准确地监测叶绿素a的浓度变化和分布,其在内陆湖泊水质遥感监测方面具有良好的应用前景。文章通过星地同步地面实验,建立起巢湖水体的叶绿素a浓度遥感反演模型,利用2009年4月至2010年3月的环境一号卫星CCD数据,分季节对巢湖叶绿素a行动态监测和分析。结果表明,巢湖叶绿素a具有明显的时空分布特征,夏季叶绿素a浓度最高,冬季最低,秋季高于春季;西半湖湖区叶绿素a浓度一般高于东半湖湖区,西北部和中部湖区空间变化比较大,东部湖区变化较小。

关 键 词:环境一号卫星  巢湖  叶绿素a  动态监测

Abstract:Environmental Satellite 1 CCD data can monitor chlorophyll-a timely and correctly due to its short revisiting period and high spatial resolution.So the Environmental Satellite 1 CCD data has good application prospect in chlorophyll-a remote sensing monitoring.Through the experiment of satellite-ground synchronization,the objectives of this paper are to build the model of retrieving chlorophyll-a concentration in Chaohu Lake. The chlorophyll-a concentration in Chaohu Lake is dynamically monitored and analysed in different seasons using the Environmental Satellite 1 CCD data from April in 2009 to March in 2010. An obvious spatial-temporal distribution was found for chlorophyll-a concentration in Chaohu lake, chlorophyll-a concentration had the maximal value in summer and the minimal value in winter, the average chlorophyll-a concentration in autumn was higher than that in spring.The chlorophyll-a concentration in the west of lake was higher than that in the east. Great changes have taken place in the northwest and middle of the lake,while the changes are smaller in the east.
Keywords:HJ-1 satellite  Chaohu lake  Chlorophyll-a  Dynamic monitoring
