基于高分六号卫星观测数据监测太湖蓝藻水华研究
摘要
Abstract
Based on the GF-6satellite data in 2018 and 2019,this paper uses the Normalized Difference Vegetation Index to extract cyanobacteria blooms in Taihu Lake,and verifies the excellent monitoring effect of red edge band on cyanobacteria blooms.The results show that cyanobacteria blooms occur most frequently in Meiliang Bay,the north of the central area of Taihu Lake and the northern part of West Taihu Lake.NDVI has a representative minimum global and seasonal threshold range,and the overall threshold has a high correlation with the summer threshold,and the stability of the threshold range of the red edge Ⅰ band(0.71 band)is better than that of the red edge Ⅱ band(0.75 band)and the near-infrared band(0.83 band),and the minimum threshold range is normal distribution.Therefore,the GF-6 satellite has the potential to monitor the cyanobacteria bloom in Taihu Lake and can be used to quickly monitor the outbreak of cyanobacteria bloom in Taihu Lake.关键词
