泾河平凉段水环境容量分析与对策

Analysis and Countermeasures on Water Environmental Capacity of Jing River in Pingliang Section

水环境容量是衡量一个水域水质状况的重要指标,泾河作为平凉市的主要河流,其环境状况与人们的生产、生活息息相关。将泾河平凉段分为三个控制单元,分别分析其属性和水质达标情况,在对污染源进行调查研究之后,采用一维模型计算其水环境容量,并将其与现行排污量进行比较,得出该流域的剩余水环境容量,同时提出了泾河平凉段水环境治理的具体对策。

Water environmental capacity is an important index measuring water quality of rivers. As a main river in Pingliang, Jing River＇ s environmental status is closely linked with peoples＇ production and life. Jing River in Pingliang section was divided into three control units, and their attributions and status reaching water quality standards were analyzed. After the investigation on pollution sources, the water environmental capacity was calculated using one-dimensional model, compared with the current discharge capacity, and the remaining water environmental capacity was obtained. Some specific countermeasures governing the water environment of this river were put forward.
