水生态环境中不同建材基质附着藻类的生物学特征

[目的]开展不同附着藻类生物学特征的试验，分析水质指标与藻类生物学特征的关系，为筛选科学合理的附着基质，丰富附着藻类着生提供科学支持。[方法]通过模拟试验，分析3种不同建材基质(花岗岩、聚乙烯网、木板)附着藻类的生物学特征，筛选出效果好且易于资源化利用的附着基质类型。[结果]花岗岩和木板基质的附着藻类群落更加稳定，生物学特征更优，功能性藻类种类更多，更有利于发挥附着藻类在水环境中的生态效应。[结论]综合考虑可利用程度和操作的难易程度，花岗岩基质是3种基质中最合适的基质。

Biological Characteristics of Periphytic Algae on Different Building Material Substrates in Water Eco-enrironment

[Objective] The biological characteristics of different attached algae were determined and the relation between water quality indicators and algae biological characteristics were analyzed in order to provide scientific support for screening scientifically reasonable attached substrates and enriching the growth of attached algae. [Methods] The biological characteristics of algae attached to three different building material substrates (granite, polyethylene mesh, wood) were analyzed using simulation experiments. The types of attached substrates having good effects and easy resource utilization were selected. [Results] The periphytic algae communities attached to granite and wood substrates were more stable, and had better biological characteristics and more functional algae species, and thereby were more conducive to providing an ecological effect of periphytic algae in the water environment. [Conclusion] The granite substrate was considered to be the most suitable substrate among the three tested substrates because of its ready availability and ease of use.
