摘要
本文以云南大理某高速公路建设对沿线水环境的影响为研究对象,采用单因子污染评价法进行水环境质量评价。结果表明,高速公路建设过程中对地表水中的COD和SS含量的贡献率较大,COD和SS是地表水中主要污染物质;地下水中总大肠杆菌在监测期内评价等级为Ⅴ类,由初期的Ⅰ类变化为后期的Ⅴ类。
This paper takes the impact of the construction of a highway in Dali,Yunnan on the water environment along the line as the research object,and uses the single-factor pollution evaluationmethod to evaluate the water environment quality.The results show that the expressway construction process has a greater contribution rate to the content of COD and SS in surface water,and COD and SS are themain pollutants in surface water;the total E.Class I changes to the later class V.
