Abstract:This article studied the spatial distribution and the variability of suspended solids concentration (SSC) in the coast water of Hongkong leveraging the HJ-1A/B CCD data of 2009~2012and the measured data. The remote sensing inversion model had been set up. Based on which, the analysis was conducted by means of the geostatistical method. SSC in the north part of the area (i.e., the Shenzhen bay) was higher than other areas all the year around; SSC in the northeast part of area (i.e., the estuary of the Pearl River) fluctuated remarkably from seasons to seasons; SSC in the south of Lautau island was relatively lower all the year around, and fluctuated from seasons to seasons. The study of data from 2009to 2012indicated that the total SSC in the area was low. Specifically, the average SSC was 12.25mg/L, and SSC was higher in the north part and lower in the south part; SSC was characterized as remarkable variation in spatial and temporal dimensions. Besides, SCC showed a strong autocorrelation in spatial dimension, where the value of nugget/sill was lowest in March (0.0005).
