对1991年～2000年湘江衡阳段干流水体中氨氮、亚硝酸盐氮和硝酸盐氮在不同江段、不同年际的时空变化规律进行了分析.结果表明,亚硝酸盐氮和硝酸盐氮含量有逐年升高的趋势,氨氮含量年际变化幅度较大,是湘江衡阳段水体超标指标之一.对水体中氮的来源作了分析,并提出了保护水资源的措施.

Space-time variations of nitrogen content in different river sections from 1991 to 2000 in Hengyang Part of Xiang River was studied. The results showed that nitrite and nitrate contents in water body tend to increase yearly. The variation of ammonia contents is very great, and ammonia is one of the exceeding quota in Hengyang Part of Xiang River. The Source of nitrogen in water was analyzed and the measurement...
