摘要
主要围绕生物对营养的竞争作用,研究粉绿狐尾藻与铜绿微囊藻在较低营养水平水质中的相互影响机制.通过测定藻密度和水质指标,得出以下结论.在较高的初始藻密度条件下,粉绿狐尾藻更具竞争优势,表现出密度依赖效应,能够更有效地争夺水体中的营养成分.同时,铜绿微囊藻对总磷浓度的变化敏感性更高,但对总氮的浓度要求较高.
Abstract
Mainly focusing on the competitive role of organisms in nutrition,this study investigates the mutual influence mechanism between myriophyllum aquaticum and microcystis aeruginosa in water quality at lower nutrient levels.By measuring algal density and water quality indicators,the following conclusions were drawn.Under higher initial algal density conditions,myriophyllum aquaticum have a competitive advantage,exhibit density dependent effects,and can more effectively compete for nutrients in water bodies.Meanwhile,microcystis aeruginosa is more sensitive to changes in total phosphorus concentration,but has higher requirements for total nitrogen concentration.
