摘要
为探明白洋淀水质和沉积物理化参数存在的空间异质性特征,本研究选取白洋淀三个典型断面,分别对其上覆水及沉积物进行收集测定,结果表明,白洋淀水质和沉积物理化参数均存在明显的空间差异性。结合主成分分析,解析出化学需氧量是目前影响白洋淀水环境的主要因子,Spearman关联分析显示,水-沉积物界面存在明显的相互关系,水体pH值与沉积物中各环境参数联系紧密,呈现显著的相关性。
To explore the spatial heterogeneity characteristics of the water quality and sediment physicochemical parameters in Baiyangdian,the overlying water and sediment were collected and measured physicochemical parameters from three typical sections,respectively.The results show that the water quality and sediment physicochemical parameters of Baiyangdian have significant spatial differences.Combined with principal component analysis,it is resolved that chemical oxy-gen demand is the main factor affecting the water environment of Baiyangdian at present.The Spearman correlation analysis results show that there is a relatively obvious correlation at the water-sediment interface,and the water pH is closely related to the environmental parameters in sedi-ment,which has a significant correlation.The research results can provide further theoretical refer-ence for the governance and protection in Baiyangdian.
