- •
A correlation of BSi and suspended sediments was built for the Changjiang River.
- •
Middle and lower of the Changjiang basin yielded more BSi than upstream.
- •
BSi/(BSi + DSi) ratio has decreased from 0.47 before 1980s to 0.19 in 2013–2014.
- •
BSi dissolution in the TGR contributes to 4–16% of DSi in the Changjiang River.
