摘要
利用单因子水质标识指数法、综合水质标识指数法、模糊数学法和综合污染指数法4种水质分析评价方法并结合季节性Kendall趋势检验法对汤溪水库2014-2018年共5年的水质状况进行综合分析评价。这4种不同的评价方法结果均表明汤溪水库水质总体良好,且与Kendall趋势分析检验的结果趋于一致,但是不同的分析方法受影响因子干扰的程度不同,导致最终判定的水质类别也存在一定差异。因此对水库水质的综合分析评价需结合自身需求,针对性地选择适合的分析方法。
Comprehensive evaluation of Tangxi Reservoir water quality status from 2014 to 2018 was conducted by four analysis and evaluation methods including single factor water quality identification index method, comprehensive water quality identification index method, fuzzy mathematics method and comprehensive pollution index method, combining with seasonal Kendall trend test method. The evaluation results out of these four methods all demonstrate the water quality of Tangxi Reservoir is generally good and has a tend consistent with that of the Kendall trend test and analysis. However, different analysis methods are affected by the influencing factors to different extent,which leads to certain differences between the finally determined water quality categories. Therefore, suitable water quality comprehensive analysis and evaluation method shall be selected corresponding to the actual needs of reservoir.
