- Abstract
Inversion of water components concentration of inland water body was hotspot and difficulty problem in water quality remote sensing. Based on the measured data of the concentrations of Chlorophyll-a in tropical islands waters area of China and the recent synchronous remote sensing image data, the inversion simulation was carried out to realize the spatio-temporal monitoring of the sea area. Through the analysis of the correlation between the radiation intensity of the water supply in the 1-4 bands of Wuzhizhou Island in 2010 and 2014 and the Chlorophyll-a concentration in Wuzhizhou Island, the Chlorophyll-a concentration inversion model was established. The distribution of Chlorophyll-a concentration in the study area was simulated, and the change of Chlorophyll-a concentration in four years was analyzed. The results showed that the Chlorophyll-a concentration in the blue and green bands was higher, and the ratio of the two as the independent variables could effectively reflect the Chlorophyll-a concentration in Wuzhizhou Island. The Chlorophyll-a concentration increased significantly from 2010 to 2014. Due to the impact of human activities, the concentration of Chlorophyll-a in tourism concentrated areas was low.
