摘要
根据2012~2014年4个月份滦河口邻近海域的海洋监测资料,分析了海水叶绿素a的时空分布状况。利用多元线性回归方法,以叶绿素a为因变量,筛选出水深、pH值、DO、COD、活性磷酸盐、亚硝酸盐、铵盐7个影响显著的关键环境因子,建立了最优的多元线性回归统计模型;利用单因子相关性分析结果,进一步证明了海水叶绿素a与众多的海水环境因子表现出多元相关性,说明水体中浮游植物的生长繁殖是众多环境因子综合作用的结果。
The temporal and spatial distribution of seawater chlorophyll-a was analyzed according to the marine monitoring data of Luanhe coastal area collected between 2012 and 2014. Multiple linear regression analysis was utilized to finding out seven key environmental factors as independent variables, and optimal multiple linear regression statistical model. In addition, the single-factor correlation analysis was utilized to further proving the correlation between chlorophyll a and environmental factors. Chlorophyll a can be regressed linearly to these actors, suggesting that the growth and development of phyto-plankton are the overall effects of these factors.
