利用卫星遥感对同一地区重复成像的特点,采用从港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港两个不同时段的0m以浅的沉积参量:1965~1984年时段沉积总量为4.59×106m3,沉积速率为2.4×105m3/a;1984~1990年时段,沉积总量为-8.4×105m3,沉积速率为-1.4×105m3/a。
Based on the characteristics of repeated images in the same area by satellite remote sensing, a method of extracting water area with different tide levels from images of different phases of the harbor was established, and the calculation formulas of tide planes and stratified summation were established. Sediment parameters and tide planes were used to calculate the shallow depositional parameters of 0m in two different periods of Haikou Harbor: the total deposition was 4.59 × 106m3 from 1965 to 1984, the deposition rate was 2.4 × 105m3 / a; 1984 ~ 1990 During the year, the total sedimentary volume is -8.4 × 105m3 and the deposition rate is -1.4 × 105m3 / a.
