摘要 周丛生物在水生生态系统的初级生产、营养循环和食物网中发挥了重要作用.而周丛生物群落的结构和功能受营养、光、大型水生植物、牧食者、沉积物、水力扰动和水位、pH和碱度的影响.其中,营养、光照、牧食者强烈地影响周丛生物的数量和生产.沉积物除直接供给附泥周丛生物营养外,还通过大型水生植物间接影响附植周丛群落.水力扰动和水位可以影响周丛生物群落的空间分布、局域密度和种类结构.pH和碱度变化主要造成周丛群落优势种的变化.展望了周丛生物的应用和研究前景. Periphyton plays a key role in primary productivity, nutrient cycling, and food web interactions in fresh- water ecosystems. There are quite a few factors such as nutrient, light, macrophyte, grazer, sediment, waterpower, water level, pH and alkalinity influencing periphytic community structure and function. In general, the mass and pro- ductivity of periphyton are strongly influenced by nutrient, light and grazer. The effects of sediment on epipelic per- iphyton are direct as nutrient source, while the effects on epiphytic periphyton are indirect through influencing macro- phytes. The periphytic spatial distribution, local density, and species structure are effected by the actions of waterpow- er and water level. Otherwise dominant species of periphyton community can be changed by pH and alkalinity. An out- look of future prospects of periphyton studies and applications were given.
