不同地表覆被下南四湖表层底泥营养元素分布特征
Distribution Characteristics of Nutrient Elements of Surface Sediments from Different Land Uses in Nansihu Lake, China
摘要
Abstract
Based on all the 29 samples taken from aquatic vegetation area, agricultural and residential area, fish culture area, natural water of Nansihu Lake, the contents of TN, TP and TOC of water surface sediments were analyzed and the characteristics of the nutrient distribution were examined in the study. Through the analysis of correlation of surface sediments and the water, the origins of these nutrients were discussed, and the level of pollution was analyzed with the organic index. The results indicated that the eutrophication had appeared in agricultural area, residential area and fish culture area, but the aquatic vegetation area and natural water were not threatened by eutrophication. On the other hand, the source of TN in surface sediments was mainly from the organic nitrogen of Nansihu Lake, and the source of TP was mainly from the inorganic phosphorus outside the lake.关键词
