Abstract

Suspended matter is an important indicator of water environment monitoring. As a model of tropical tourist island in China, the content of the suspended substance influences the development of marine tourism. In order to understand the distribution of suspended matter concentration in Wuzhizhou Island, the correlation between the band combination and the concentration of suspended matter was analyzed by EXCEL and SPSS using TM data of Landsat-5 satellite and WFV2 image data of GF-1 satellite. The inversion model with high correlation level and good ufit was selected for estimation of suspended substance concentration. The results show that the polynomial regression model with the B2/B3 ratios of the Landsat-5 TM image on June 12010 is the best, and the B4 / B3 combination of GF-1 WFV2 data on June 2, 2014 is the best . The increase of the suspended matter concentration in Wuzhizhou Island area from 2010 to 2014, especially the northwest marine bathing area, the northern diving area and the maritime recreation area were affected by human tourism activities, and the suspended matter concentration changed obviously.
