摘    要:本文在湖泊水质监测和实验室模拟的基础上,选择光照强度、温度和营养物三种环境因子做为限制因素研究藻类生长规律,得出了这些因子与藻类生长间的定量关系,并引入了藻类的死亡速率、沉降速率、浮游动物的捕食率、鱼类的捕食串以及水体的物理化学性质等参数,建立了镜湖藻类生长预测模型,该模型具有以下功能:①预测藻类生长的季节变化;②预测藻类在湖泊中的空间分布(深度);③预测湖泊在不同磷负荷下藻类生物量的变化。

关 键 词:藻类  生长动力学  富营养化    温度

Abstract:This paper selected illnminance, nutriention and temperature as three environmental limiting factors to study the law of algae growth, based on water quality monitoring of lake and laboratory modelling. It has got quantitive relation between these factors and algae growth. Some parameters are taken in such as death rate of algae, sedimentation rate, prey rate and physic-chemical characters of water body etc. model of algae growth in Jingpo lake is set up. The functions of model as follows.(1) Variation prediction of algae growth in different seasons;(2) Distribution Prediction of algae in different water depth;(3) Variation prediction of algae quantity under different phosphorus load.
Keywords:Algae  Eutrophication  Illuminance  Phosphorus  Temperature  Model
