Suspended solids concentration is an important parameter to evaluate the quality and environment
water. It has very important significance to get the time-spatial distribution information of
solids concentration in lakes for their environmental management based on the remote sensing
The four seasons’ inversion models were built according to the suspended solids concentration
Poyang Lake continuously measured in spring, summer, autumn and winter season of 2009 and 2012
combining with the regression analysis of the lake’s multi-band MODIS images in the same period.
they are used to obtain the suspended solids concentration of the lake in annual spring, summer,
and winter seasons from year 2000 to 2013. The results show that the suspended solids
Poyang Lake is higher in the center of the lake and the main channel while is relatively lower
coastal waters, what is more the concentration was increasing year by year from 2000 to 2013
value in spring and autumn but low in summer and winter. Human activities have a great influence
suspended solids concentration changes, too.
