| 摘 要： | 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.

| Abstract: | -By making use of the distinguishing features of repetitive imagery of the same area by satellite remote sensing, a method of extracting water areas at different tidal levels from the images of bays at different times was adopted to establish a calculating model for tidal surface and a method of finding a sum by layers was used to establish a calculating model for the deposition parameter. Moreover, by making use of the calcu- lating models for the deposition parameter and for tidal level, the deposition parameter for the sea area less than 0 m was calculated for the Haikou Bay at two different periods of time: during the period of 1965-1984 the total amount of deposits was 4.8x 106m3, and the sedimentation rate was 2.5X105m3/a; during the period from 1984 to 1990, the total amount of deposits was -8.9 X 105m3 and the sedimentation rate was -1.5X 105m3/a. |
