为了评价贵阳城市化河流南明河水质安全的演变规律,实现城区河段水环境质量的监测与管理工作,在实测黔中喀斯特地区南明河流经贵阳市区前后的花溪、水口寺、普渡桥3个断面2008年3月～2010年12月9个河流水环境参数的基础上,采用模糊数学方法对南明河市区段的水质安全进行综合评价分析。结果表明：城区及其下游的普渡桥和水口寺两个断面全年处于极不安全状态,花溪断面在平水期和枯水期为非常安全级别状态,但丰水期稍差,处于安全状态。南明河经过贵阳城区的过程中水体受到污染而处于极不安全状态,甚至经过长距离的河段净化也没能使得水质恢复到安全状态,这表明流域水文情势及城区社会经济行为对城市河流的水质安全具有显著的影响。

In order to assess the impact of water quality security that the Guiyang city urbanization acted to the riverine water of Nanminghe River for the water environmental quality monitoring and management work, the security of the urban riverine quality along the Nanminghe River were assessed using the fuzzy mathematics accord- ing to the 9 water environmental parameters of the site in Huaxi, Shuikousi and Puduqiao those were monthly sur- veyed alonge the Nanminghe River waterway throuthing out the ＇Guiyang city area in the Central Guizhou province during the period from March 2008 to December 2010. As a result, the water quality security have been in the most unsafe degree around the years in the both sites of the Puduqiao and the Shuikousi riverine water downing the Guiyang urban area, while the water quality security were thelbest safe degree during the lowflow and normal wa- terflow season, as well as were safe degree in the highwater season. It was suggested that the urban economical- social activities and hydr-circumstances have strikingly impacted the degree of the urban riverine water quality se- curity, for which the water quality security were the most unsafe degree either in the site of the down urban or in the site which water had been carried out a long-distance depuration and too late to refresh because of the pulluted water flowing into waterway for urban activities.
