摘要
对太白山自然保护区水质状况进行了分析,并利用单项水质评价法和综合指数法对其进行了评价。结果表明:太白山自然保护区水体呈弱酸性,重金属元素含量顺序为Zn>Cu>Cr>As>Hg>Cd。保护区水域的大部分水质指标基本符合《地面水环境质量标准》(GB3838-2002)Ⅰ类水质标准,水质状况良好。受自然因素和人为因素的影响,化学需氧量(CODCr)和汞(Hg)是影响太白山自然保护区水体环境的主要因素,但均未对环境造成不利影响。
Water quality of Taibaihshan Nature Reservation was researched and single factor index and comprehensive index were used to assess the quality. The results showed that the water was acidity, the contents of 6 heavy metals were Zn〉Cu〉Cr〉As〉Hg〉Cd. The water quality of Taibaishan Nature Reservation is good. The determining values of the majority of items reached the first class standard value of surface water, For the interaction of natural and factitious factor, the value of CODcr and the concentration of Hg were the main influencing factors, but these were not serious for environment.
