| 摘 要： | 为了探究合坝发电前后大源渡库区氮含量的时空变化规律，对大源渡库区合坝发电前5年和后5年水体中的三氮含量在不同断面、不同年际的监测数据进行统计处理并对时空变化进行分析。结果表明，库区水体亚硝酸盐氮和硝酸盐氮年均含量总体呈逐年升高的趋势；氨氮含量年际变化幅度较大，且为库区水体超标指标之一。合坝发电前后库区水体中三氮年均含量变化没有显著性差异。但若将合坝后5年与合坝前5年三氮含量年均值比较，则亚硝酸盐氮呈现显著性升高，氨氮与硝酸盐氮无显著变化。 |

| Abstract: | In order to evaluate space-time variations of nitrogen contents in the water-body of Da Yuan Du reservoir before and after the dam was jointed, monitoring data of nitrogen content of the different river sections from 1993 to 2002 in the water body were studied. The results show that nitrite and nitrate contents in the water body tend to increase yearly. The variation of ammonia contents is very great , and it is one the exceeding quota in the water body of reservoir. The variation of nitrogen contents in water body is not distinct before and after the dam was jointed. |
| Keywords: | Nitrogen content ammonia: nitrite: nitrate |
