| 摘 要： | 针对丹江口水库总氮超标问题,对作为主要集水区的汉库入库各河流进行了一整年的水量和水质同步监测。结果表明:(1)主要河流入汉库总氮量共24503t/a,湖北和陕西两省入库总氮量比例总体上与水资源量比例相当,其中,汉江干流上游陕西来水入库总氮量占68.2%,湖北主要支流包括十堰堵河(18%)、神定河(7%)、泗河(4%)、官山河(0.9%)、浪河(0.7%)剑河(0.5%)和天河(0.5%)。(2)入汉库总氮总量月变化与入库总水量变化一致,总氮入库量主要集中在5~9月,占全年的77%。(3)根据各河流水环境容量和纳污特征,可将入库河流划分为容量型、点源污染型、农业面源型和混合型等四种类型。建议对不同类型河流应采取不同控制对策,点面结合,综合防治。 |

| Abstract: | With respect of high content of total nitrogen (TN) in Dangjiangkou Reservoir,TN concentrations were determined over a whole year as well as water quality and quality on river entries to Hanjiang Reservoir. Results showed that TN amount from rivers flowing into Hanjiang Reservoir was 24,503t/a,and its distribution from river entries in Hubei and Shaanxi Province were comparable with proportion of incoming water quantity of each province. TN from incoming water of Shaanxi Province accounted for 68.2% of tota... |
