Abstract：A special sampler was made to take continous specimens of sediment(up to 2m long)from X议i Wetland．T11e
contents of total nitrogen(TN)，total phosphorous(TP)and organic matter(OM)were measured on the sediment
specimens taken from different depths，and their distributions along depth in this wetland were determined．
Concentrations of TN，TP and OM in the pore-water of sediments and the upper water body were also measured．On the
base of the measurements，the eutrophication pollution degree in the sediments Was evaluated by using the organic index
method．It Was found that the active zone of pollution was extended to a depth of 60cm below the river bed．Sediments in
the active zone were slightly-moderately polluted，and nO pollution wag observed at the depth greater than 60cm(i．e．，
relatively stable Zone)．The distributions of TN，TP and OM along depth showed a consistent trend．The amounts of TN
and TP in the pore water of shallow sediments wcrc found to be much more t
