At last the article concluded that ⑴the impact of nutrient in the sediment on water was due to surface sediment; ⑵the solubility rate of total nitrogen was higher than of total phosphorus in the sediment,and the balance system of nitrogen near the sediment interface was easy destroyed; ⑶phosphorus inwater was absorbed by the sedime.
