摘要
以巢湖为研究区,从2008年4月到11月,对巢湖水体的24个点位进行了连续的水体光谱测量,通过对蓝藻水华爆发程度与其光谱反射率之间关系的研究,确定遥感识别水华爆发级别的阈值,对四类不同爆发程度蓝藻水华光谱特征进行遥感识别,绘制巢湖蓝藻水华特征等级图。
For the study area in Chaohu Lake,Water bodies of the Chaohu 24 points for the continuous measurement of the water spectra from April 2008 to November.Through studying the relationship between outbreak degree of cyanophyte bloom and its reflectance to determine the threshold level of water bloom outbreak of remote sensing to identify.Using remote sensing to identify four kinds of cyanophyte bloom spectral signatures of different extent outbreak,and mapping algae bloom level image of MODIS images.
