“Thirteenth Five-Year Plan” Danjiang Main Stream Water Environment in Shangluo City Quality Evaluation and Trend Analysis

通过对“十三五”商洛丹江干流的水质监测数据进行评价与趋势分析,结果表明,商洛丹江干流水环境质量总体稳定,除个别断面存在轻度污染,其余断面为尚清洁,出省水质达到Ⅱ类标准,主要污染物为化学需氧量和氨氮。针对研究结果 ,结合当地水质现状与产业布局,为商洛丹江的水质改善提出可行性强的建议。

This paper evaluates the water quality monitoring data of the main stream of the Shangluodan River during the 13th Five-Year Plan and analyzes its trends. The results show that the overall water quality of the main stream of the Shangluodan River is stable. Except for some sections with slight pollution, the rest of the sections are still clean. The water quality out of the province reaches the Class II standard, and the main pollutants are chemical oxygen demand and ammonia nitrogen. According to the research results, combined with the current situation of local water quality and industrial layout, it puts forward feasible suggestions for the improvement of water quality of Shangluodan River.
