摘要:
以江苏、广东2省多点的浮萍及其生活水体为研究对象,调查浮萍种属分布、水质状况,并分析浮萍分布与水环境因子的相关性。经DNA barcoding鉴定,江苏采集的浮萍属于青萍、多根紫萍、少根紫萍、芜萍,而广东采集的浮萍均为青萍。通过对水体pH值、氨氮、硝氮、总磷、铬(Cr)、锰(Mn)、镍(Ni)、铜(Cu)、锌(Zn)、镉(Cd)、铅(Pb)11种环境因子进行测定,发现青萍对pH值、氨氮、硝氮、总磷、Mn、Ni、Cu、Zn的耐受能力较其他浮萍强,而紫萍对Cr的耐受能力较好。通过相关性分析,发现水体环境的差异会造成浮萍分布的差异,而冗余分析(RDA)发现,氨氮、pH值与浮萍分布具有显著相关性,氨氮是影响浮萍分布最主要的环境因子。而广东采集的水体氨氮浓度过高,对氨氮耐受能力较弱的浮萍品种难以存活,这也是造成广东地区浮萍品种单一的原因之一。综上所述,本研究对选择浮萍品种处理水体具有一定的指导意义。
