摘要
为了研究石佛寺人工湿地对矿业活动所产生的矿业污染物是否具有净化效果,采用模糊模式识别评价法,选取由矿业活动所产生的5个主要污染物作为评价因子,建立了模糊模式识别水质综合评价模型,对石佛寺人工湿地2014年汛期和非汛期进口、中间和出口水质进行评价。分析了各断面水质级别及其特征值的变化情况,结果表明,石佛寺人工湿地对矿业活动所产生的污染具有明显的净化效果,且汛期好于非汛期。该方法能全面客观地反映水质现状及水污染的变化情况。
In order to study whether Shifosi constructed wetland has purification effect to mining pollutants generated by the mining activities or not,this paper uses fuzzy pattern recognition assessment method,chooses five major pollutants generated by the mining activities as assessment factors,and establishes a fuzzy pattern recognition model for comprehensive water quality assessment.The method is used to evaluate the water quality of import,middle and export of Shifosi constructed wetland in the flood season and non？flood season of 2014,and the changes of water levels and their characteristic values in each section are analyzed.The results show that Shifosi constructed wetland has obvious purification effect to mining pollutants generated by the mining activities,and the purification effect in the flood season is better than in the non-flood season.This assessment method can comprehensively and objectively reflect the actual situation of water quality and the changes of water pollution.
