摘要: 通过浮游植物的增殖态势与理化因子的友关联比较,以空间理论数学为基础,按规范性、偶对称性、整体性、接近性和光滑离散函数等原则,并定义灰导数和灰微分方程,由此建立灰色动态模型,研究大鹏湾浮游植物增殖与海水环境要素间的关系结果表明,浮游动物、Fe、Mn和溶解氧对浮游植物增殖密度有比较重要的影响.Abstract: The relation between the dynamics of phytoplanktan aad essential environmental factors of seawater has been studied.According to the cattparisons between environmental factors of seawater,and on the basis of mathematical space theory and the four principles of normalization,even syrranetry,globality and proximity,smoothing discrete function,the grey derivative and the grey differential equation have been defined,the grey models and relation to the factors(the seawater phiysical and chemical factors) are estimated.The calculated results indicate that rpoplanktom,Mn,Fe and dissolved oxygen are the most important factors.
