湖北省典型浅水湖泊冬季氮的空间分布特征研究——以洪湖和武汉东湖为例
The spatial distribution of Nitrogen in typical shallow lakes in winter of Hubei province
摘要
Abstract
To study the spatial distribution characteristics of nitrogen in shallow lakes, the samples in two typical shallow lakes (Honghu Lake and East Lake) were analyzed in winter in 2010. Honghu Lake is the largest lake away from city in Hubei province, East Lake is the largest urban lake in Hubei province. Through the analysis in the laboratory, the total-nitrogen, ammonia nitrogen, nitrate nitrogen and nitrite nitrogen of two lakes were obtained. The results indicated that, in two lakes, the concentration of the ammonia nitrogen was the highest, the nitrate nitrogen second, and nitrite nitrogen the lowest. In addition, the average concentration of total-nitrogen, ammonia nitrogen and nitrate nitrogen in Honghu Lake were greater than these in East Lake in winter, the average concentration of nitrite nitrogen of Honghu Lake is lower than the one in East Lake in winter. The spatial distribution patterns of different nitrogen species in two lakes in winter were studied by the ARCGIS spatial interpolation. The results indicated that, the spatial distribution of the concentration of ammonia nitrogen was in agreement with the one of total nitrogen. The concentration of various forms of nitrogen near the sewage outlets and the space deep influenced by human activity were bigger.关键词
