【摘要】 为了解韶关丹霞山风景区近年水质状况及动态,于2017～2018年间,对风景区的6个水质站点,每个站点选取6个水化指标进行调查,分析该区域水化指标的变化特征及站点间的相关性,采用单因素方差分析和PCA分析,进一步分析该地区的污染状况。结果表明,调查期间,丹霞山风景区各水质站点在丰水期和枯水期各项水化指标变化规律不同,水库与河流站点间营养盐指标差异显著,水库水质优于河流水质,枯水期水质优于丰水期。更多还原

【Abstract】 In order to know the dynamic state of water quality and water quality assessment in Danxia mountain of Shaoguan province, we chose survey result of six factors of water chemical from 2017 to 2018 in this district, where six water quality loci were chosen. Analyzing the change of water quality and the concentration among these loci, usedsingle-factor anova and PCA analysis, further to assess the state of pollution in this area. The results showed between flooding season and dry season, the variation of water quality among the loci was different. There was significance of difference between reservoir loci and river loci in Chemical factors. The water quality of reservoir was better than that in river loci, and water quality in dry season was better than that in flooding season.更多还原
