大鹏湾生态因子灰关联分析

研究大鹏湾夜光藻、反曲原甲藻、浮游动物种群增殖与浮游动物和海水理化因子之间的关系，采用的方法是根据它们的种群增殖态势与浮游动物和理化因子的比较，依据空间理论的数学基础，按照规范性、偶对称性、整体性和接近性这四条原则，确定参考数列（母序列：夜光藻和反曲原甲藻、浮游动物）和若干比较数列（子序列：浮游动物和海水理化因子）之间的关联度．给出各因子对母序列影响的排列次序．其结果是，对大鹏湾生态环境起主要影响的因子有浮游动物、锰、铁和溶解氧

Analysis of Grey Incidence of Ecology Factor in Dapeng Bay, South China Sea

The relations between the growth of Noctiluca scintillans,Prorocentrum sigmoides Bohm,zooplankton and physical,chemical factors of seawater were studied in this paper. Based on the comparion of zooplankton, physical and chemical factors of seawater, the population trends of the growth state of Noctiluca scintillans, Prorocentrum sigmoides Bohm were studies,mean-while according to the mathematical basis of space theory and the four principles (normal, even symmetry, globality and proximity), the gred incidence was estimated, those are the incidence degree of reference sequence, Noctiluca scintillans, Prorocentrum sigmoides Bohm, zooplankton and several comparasion series (zooplankton, physical and chemical factors of seawater). The calculation results indicated that zooplankton,Mn,Fe, and dissolved oxygen were the most important factor.
