清河流域水环境质量监测与评价研究

近年来,随着全球各地城市化和工业化进程的不断加快,以及人类对河流水生态系统资源的不合理、掠夺式利用,河流水生态系统遭到严重破坏,各地河流相继出现水质恶化、水文条件改变、物种多样性退化、生境条件恶劣等诸多问题。文章对辽河主要支流清河水生态系统的水质状况进行了研究,并于2012年6月,对清河流域22个监测断面水质状况进行了实地调查,对其水质状况进行了评价,结果表明:22个监测断面中,达到Ⅲ类水质断面的有8个,Ⅳ类7个,Ⅴ类1个,劣Ⅴ类6个。其中6个劣Ⅴ类断面分别因氟化物、氨氮、总磷浓度超标而为劣Ⅴ类。

Water Environmental Quality Monitoring and Evaluation Research in Qinghe River

With the acceleration of global urbanization and industrialization and unreasonable utilization of water, river aquat- ic ecosystems are seriously damaged in recent years. The deterioration of water quality, changes in hydrological conditions, degra- dation of species diversity, poor habitat conditions happened in many rivers. This article conducted research on Qinghe River - the tributary of Liaohe River. Fieldworks on 22 monitoring sections were conducted to evaluate the water quality in June 2012. The re- sults show that there are only 8 monitoring sections can reach water quality Ⅲ, seven reach water quality Ⅳ, one reaches water qualityⅤ and six reach inferior water quality Ⅴ for the total 22 monitoring sections. Six sections reach the inferior water qualityⅤ because of the fluoride ammonia and TP.
