| Abstract: | This paper taked Sanjiang Plain Hamatong river watershed as a study area, starting with the change situation of each pollution index in reed plants, wetland water and the wetland sediment, the article studied the purity effect that natural wetland to agricultural non-point pollution. The results showed that the concentration of nitrogen and phosphorus decreased clearly after purifying wetlands. The removal rate of phosphorus was up to 61.90% and nitrogen was up to 80.36%. |
