【摘要】 采用实地水质采样分析、水面光谱测量等实地监测 ,并结合NOAA气象卫星遥感信息 ,对巢湖水华进行星地同步调查监测。结果表明 ,蓝藻叶绿素的存在使得进入近红外波段水体反射率明显上升 ,基于这一光谱特性以及蓝藻特有的漂浮特性 ,可利用NOAA卫星监测巢湖等内陆大面积的严重污染湖泊蓝藻水华的分布状况。更多还原

【Abstract】 A synchronous investigation combining field sampling/analysis work and spectral measuring by NOAA satellite has been carried out in Chaohu Lake, a large lake that is undergoing heavily pollution and eutrophication in Anhui Province. NOAA data showed that high concentration chlorophyll a caused by blue green algal bloom over the lake gave rise to an obvious increase of the lake water reflectivity in near infrared spectrum.更多还原
