利用卫星遥感对同一地区重复成像的特点，采用从海湾不同时相的影像中提取不同潮位的水域面积的方法，建立潮位面算式和采用分层求和的方法建立沉积参量算式。利用沉积参量算式和潮位面算式计算了海口湾两个不同时段的０ｍ以浅的沉积参量：１９６５～１９８４年时段沉积总量为４．８×１０６ｍ３，沉积速率为２．５×１０５ｍ３／ａ：１９８４～１９９０年时段沉积总量为－８．９×１０５ｍ３，沉积速率为－１．５×１０５ｍ３／ａ。
Based on the characteristics of repeated images of the same area by satellite remote sensing, a method of extracting water area with different tide levels from images of different phases of the Gulf is proposed, and a mathematical formula of sediment parameters is established by using the method of stratified summation. Sediment parameters and tide planes are used to calculate the shallow depositional parameters of 0m in two different periods of Haikou Bay: the total sedimentary volume is 4.8 × 106m3 from 1965 to 1984, and the deposition rate is 2.5 × 105m3 / a: 1984 The total sedimentary volume in 1990 ~ -8.9 × 105m3, deposition rate of -1.5 × 105m3 / a.
