摘要
根据2014年4月和8月19宗中小型水库水质监测数据,运用主成分分析方法对这些水库丰水期水质进行分析与评价。结果表明19宗水库中的溶解氧与五日生化需氧量、氨氮、总磷、总氮以及高锰酸盐指数表现出较强的相关性;铁与锰、硫酸盐、氯化物相关性较强;挥发酚与氰化物有较强相关性。影响水库水质的主要指标为溶解氧、BOD5、氨氮、总磷、总氮、高锰酸盐指数、氰化物和挥发酚,19宗水库以新坛水库水质最好,雷坡坑水库水质最差。
The water quality of 19 small -middle reservoir was analyzed in this paper based on April, August in 2014, ZhanjiangCity. The correlation and principal component analysis between physical factors and chemical factors were studied. The resultsshowed that Significant correlations were found between dissolved oxygen and five - day bio - chemical oxygen demand,permanganate index, ammonia nitrogen, total phosphorus, total nitrogen. The correlation of Phenol concentration and total cyanideconcentration, Fe, Mn Sulphate and Chloride were obvious. DO and BOD5 , CODM,1, NH3 - N, TP, TN, Phenol and TCN were keyfactors, which iffluenced the water quality of these reservoirs. The water quality of Xintan Reservoir was the best one, andLeipokeng Reservoir was the worst one.
