摘要
对 1990年 3月 30日～ 6月 2 5日在大鹏湾盐田海域的海水采样结果 ,用灰色理论的系统分析方法研究并计算大鹏湾地区海水中的拟尖刺菱形藻与浮游动物数量等 15个海水理化因子变化的灰关联度 ,关联排序结果表明 :浮游动物、Fe、浊度、Me、DO、V、Se、酸碱度、盐度和温度对拟尖刺菱形藻的种群增殖态势有着较大的影响。进而建立灰色系统模型 {GM (1,h)
Based on the samples taken form the seawater of the salt field in Dapeng Bay of South China sea from March 30th to June 4th of 1990, the systematic analytical method of grey theory is used to study and calculate grey relative values between Pseudonitzschia pungen and 15 various relative physical chemical factors of seawater separately in Dapeng Bay. The rseult of relative values and their permutation indicates that Plankton, Fe, Turbidity, Mn, Dissolved Oxygen, V, Se, pH, Salinity and Temperature have more influence on this kind of alga than any other factor. Further more, the grey relative model {GM(1, h)} is established and used to identify and analyze the trends of population growth of P. pungens .
