Abstract The paper studied anic matter contents position and the degree of humification of the surface sediment
of Lake Wuliangsuhai by chemical method. Correlation between sediment humus and physical-chemical factors were also discussed.
The results showed that anic matter of the surface sediment varied from 1. 06% to 5. 38% . Their distribution characteristics
, ,
were related to hydraulic cond
