摘  要：
随着人口的持续增长和工农业的迅速发展,举水干流的纳污能力日益成为制约流域内城镇发展的重要因素。根据举水干流水文水质资料,分区计算了举水干流纳污能力。利用丹麦DHI MIKE21软件,建立了二维水动力(HD)和对流扩散(AD)模型,模拟得到了举水干流中下游段水质变化趋势图,并进一步分析了举水干流主要污染物纳污能力。总体来看,部分河段纳污能力有限,为达到污染物入河总量控制目标,举水流域仍需从城乡生活污水处理、农业面源治理、加强交界断面水质监测等方面加大污染防治力度,以实现水资源的可持续发展。

摘  要：
With the steady increase of population and rapid development of industry and agriculture, the water environmental capacity of the Jushui River is becoming an important factor restricting the development of cities and towns in the basin. Based on the hydrological and water quality data, the water environmental capacity of the Jushui River was calculated in sections. Based on MIKE21 software, two dimensional hydrodynamic(HD) and convection-diffusion(AD) models were established, the trend map of water quality variation in the middle and lower reaches of the Jushui River was obtained by simulation, meanwhile, the water environmental capacity of the main pollutants were analyzed. In general, most river reaches have limited capacity to absorb pollution. In order to achieve the goal of controlling the total amount of pollutants entering the river, it is needed to strengthen pollution prevention and control from the aspects of urban and rural domestic sewage treatment, agricultural non-point source controlling, and water quality monitoring at boundary sections, so as to realize the sustainable development of water resources.
