The estimate of sea ice resources quantity in the Bohai Sea based on NOAA/AVHRR data

P731.15; The research on sea ice resources is the academic base of sea ice exploitation in the Bohai Sea.According to the ice-water spectrum differences and the correlation between ice thickness and albedo,this paper comes up with a sea ice thickness inversion model based on the NOAA/AVHRR.data.And then a sea ice resources quantity (SIQ) time series of Bohai Sea is established from 1987 to 2009.The results indicate that the average error of inversion sea ice thickness is below 30％.The maximum sea ice resources quantity is about 6× 109 m3 and the minimum is 1.3x 109 ma.And a preliminary analysis has been made on the errors of the estimate of sea ice resources quantity (SIQ).
