Spatial Community Structure of Periphyton Assemblages in the Taizihe River Basin

  • 摘要: 以辽宁省太子河流域为研究范例,调查了全流域内69个采样点的着生藻类群落和水环境理化特征,并且以着生藻类的群落结构为基础,对太子河流域的水生态系统类型区进行了划分. 结果表明,太子河流域着生藻类群落结构具有明显的空间异质性. CCA(典范对应分析)结果显示,驱动全流域着生藻类群落结构形成的水环境因子为电导率、ρ(TDS)(TDS为总溶解固体)和ρ(TN). 基于着生藻类的群落结构特征,将太子河流域划分为3个着生藻类类型区:第1分区为太子河上游的森林多水区,第2分区为中游低山丘陵森林区,第3分区为下游平原农业区. CCA结果还显示,显著影响第1分区、第2分区及第3分区的着生藻类群落结构的环境因子分别为ρ(NO3--N)、ρ(TN)及ρ(总溶解固体)和硬度.
