摘要：Red tides are usually caused by dinoflagellates and inflict great damages to coastal fisheries,especially to prawn culture in the west coastal area of Buohai bay. A remote sensing technique by use ofLandsat TM data for mapping of red tides in their stages has been developed using phytoplankton pigmentand red colored material as the indicators. Pigments and red colored material in near surface sea waterwere measured in the Buohai bay by thematic lilapper on Landsat. Sea truth data were simul taneouslycollected during the red tide occurred. TM data digital image was processed to abstract thematicinformation i.e. pigment and red colored material. The thematic images indicated the highest correlationwith sea truth data employed. The most reliable procedure for the two indicator's distribution weredetermined to be (TM2-TMl)/(TM2+TMl)+TM5 and (TM3-TMl)/(TM3+TMl)+TM5' Detailed distribution maps of themin near surface water were obtained. The red tide area was classifIed with the two indicators from thecompared clear water area from the two thematic images. Even though further study should be necessary,it shows a strong applicability of remote sensing data on the problems of red tide
