【摘要】 应用灰关联方法对 2 0 0 1年 1 0月至 2 0 0 2年 7月柘林湾海域的海水采样结果进行数据分析 ,在磷酸盐、硅酸盐等 1 1项生态因子中找出影响浮游植物密度的关键因子 .根据这个结果 ,进一步建立了以这些关键因子为自变量的线性回归模型 ,模型最后的分析结果和灰关联分析的结果一致 ,即 Fe、水温、浊度是影响柘林湾浮游植物密度的关键因子 .更多还原

【Abstract】 Applying grey incidence-regression analysis method in this paper, we process data analysis of the samples taken in the period from October 2001 to July 2002 from seawater in Zhelin Bay, and find the key factors that affect phytoplankton density from eleven ecological factors such as phosphate and silicate, etc, and further establish the linear regression model with variables of these key factors. The conclusions between model analysis and grey incidence analysis consist, namely Fe, water temperature and turbidity are the key factors that affect phytoplankton density.更多还原
