摘　　要：基于半经验遥感模型,开展广东省雷州湾SPOT-5影像不同水深范围的遥感反演及误差分析,给出不同模型对应的最佳水深范围和不同水深范围的最佳反演模型,结果如下：红光单波段模型、红光-绿光双波段模型、绿光-红光-近红外三波段模型均在2～5m水深范围内反演误差最小,分别为16.7%,13.2%和17.1%。0～2m水深范围内,红光-近红外双波段模型反演误差最小,为34.3%；2～5m水深范围内,红光-绿光双波段模型反演误差最小,为13.2%；5～10m水深范围内,红光-近红外双波段模型反演误差最小,为19.3%；10～20m水深范围内,三波段模型反演误差最小,为31.5%。Remote sensing inversions of different water depth ranges and their error analysis are made for SPOT-5image in the Leizhou Bay,Guangdong Province,by using a semi-empirical model.The best water depth ranges corresponding to different models and the best inversion models for different water depth ranges are presented.The results show that in the depth range from 2to 5m,the red light single band model,the red-green dual band model and the green-red-near-infrared three band model all have a minimum retrieval error of 16.7%,13.2%and 17.1%,respectively.In the depth range from 0to 2m,the red-near-infrared dual band model produces a minimum retrieval error of 34.3%.In the depth range from 5to 10m,a minimum retrieval error of 19.3%is obtained by using the red-near-infrared dual band model.In the depth range from 10to 20m,the minimum retrieval error from the green-red-near-infrared three band model is 31.5%.
