摘　　要：在一些特殊的河段或地形条件下,渗渠取水在供水安全保障方面发挥着重要作用。运用内梅罗污染指数法对海浪河某傍河型渗渠水源地附近的河水水质、渗渠运行期间的渗渠水水质,以及渗渠停用后渗渠周围地下水水质进行了对比分析,结果表明,渗渠运行期间河水的水质综合评分在1~2之间(Ⅱ类水),同期的渗渠水水质综合评分在0.5左右(Ⅰ类水),在渗渠停用后周围地下水水质综合评分在2左右(Ⅲ类水);可见,渗渠水质优于河水。因此,在适宜地段合理布设渗渠,可进一步保障供水安全。Infiltration gallery plays an important role in water supplies for some special river. In order to assess the impact of infiltration gallery on water quality,a contrastive analysis between the Hailang River,infiltration gallery and local groundwater was carried out with the Nemerow index method. The results revealed that the water quality of the infiltration gallery was better than that of the Hailang River due to the natural filter of the soil. However the local groundwater was getting polluted with the use of chemicals and fertilizers. Therefore,optimizing the water-intake patterns of infiltration gallery could reduce the risks of water supplies and the water treatment requirements for a surface withdrawal.
