摘　　要：以郑州市某住宅小区内大型景观水体为研究对象,依据《地表水环境质量标准》(GB3838-2002)和《景观娱乐用水水质标准》(GB12941-91),通过5个监测点位的7项主要评价指标的监测数据变化,评价景观水体的水质状况。应用综合营养状态指数法评价景观水体营养化程度,结果表明,5个监测点位均呈现中营养化。通过镜检分析判定了景观水体中的藻类类别。在景观水体富营养化成因分析的基础上,建议通过提升水体自净能力、增设内回流水动力设施、完善水生态系统,以改善景观水体水质并减少其富营养化程度。Large-scale landscape water body in a residential quarter in Zhengzhou City was taken as a case,and its water quality was evaluated according to the“Environmental quality standard for surface water”(GB 3838-2002)and“Water quality standard for scenery and recreation”(GB 12941-91)through examining the variation of monitoring data about seven major evaluating variables acquired from five sampling spots.By using the comprehensive trophic state index method to assess the trophic level of landscape water body,it was shown that the five sampling spots were all in medium eutrophic level,and algae species herein were identified through microscopic examination.Based on analysing the causative factors of eutrophication,it was suggested to improve the water quality and mitigate the eutrophic level through enhancing the assimilative capacity of water bodies,equipping hydrodynamic facilities for inner reflux and bettering the aquatic ecosystem.
