摘要
在2007年左江流域花山景区段丰水期(7月)及枯水期(11月),设置4个监测断面,监测分析溶解氧、高锰酸盐指数、化学需氧量、pH值、粪大肠菌群数5个水质指标,研究调查国家级风景名胜区(花山岩画)水域水质现状,探讨人类活动对当地水环境质量的影响。依据国家地表水GB3838-2002评价标准,风景区周边水环境质量大多处于Ⅱ类以上标准,但化学需氧量在3#断面一直为Ⅲ类标准,是该区域水体污染的限制性因子。分析水质恶化原因,并对水资源保护提出相应的措施。
In July and November of 2007,four monitor sections in Huashan Tour District of Zuo River Basin were set up in order to monitor and analyze the dissolved oxygen,permanganate index,chemical oxygen demand,pH value and fecal coliform number.The water quality in national-level scenic and historic interest district（Huashan Rock Paintings）was analyzed.The effects of human activities on the local water environmental quality were discussed.According to national surface water evaluation standard（GB 3838-2002）,the water quality was in the scope of national Ⅱ class water standard,but chemical oxygen demand in 3# section maintained Ⅲ class all the time,which was the restricting factor of water pollution in this area.The reasons for the water quality deterioration were analyzed.And the measures for the water resources protection were put forward.
