Abstract:
The vertical distribution of TN, TP and organic matter (OM) contents in the sediment of ModernFuyang Original Wetland Park was analyzed, and the eutrophication of the sediment in the target river was evaluated by the organic index method. The results showed that the overall profiles of the contents of TN, TP and OM in the sediment of the target river were rising with the depths, and the correlation of the three was significant in the vertical direction. According to the variation trends of TN and OM, it was speculated that the lower sediment had a higher risk of organic pollution. Due to the particularity of the distribution of sediment pollutants, covering measures could be used as a means of shortterm control. As sediment was the main source of internal pollution, dredging was considered to be the longterm remediation scheme. However, the depth of dredging needed to be further studied.
