【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．更多还原

【Abstract】 The relation bebween the dynamics of phytoplankton and essential environmental factors of seawater has been studied. Accord ing to the comparisons between environmental factors of seawter, and on the basis of mathematical space theory and the four principles of nor malization, even symmetry, globality and proximity, smcothing discrete function, the grey denvative and the grey differential equation havebeen defined, the grey models and relation to the factors (the seawater phiysical and chemical factors) are estimated. The calculated resultsindicate that zooplanktons, Mn, Fe and dissolved oxygen are the most important factors.更多还原
