摘要
运用灰色理论的系统分析模型研究叶绿素－ｂ与水温、浮游动物、盐度、溶解氧、酸碱度、磷酸盐、亚硝酸盐、硝酸盐、铁和锰等１０个海水理化因子间的关系。所有样品数据采自深圳大鹏湾的盐田海域。灰关联值的计算及其排序结果表明：硝酸盐、磷酸盐、亚硝酸盐和酸碱度对叶绿素－ｂ的浓度比其他海水理化因子有着较大的影响。本文建立叶绿素－ｂ与这４个海水理化因子的灰模型｛ＧＭ（ｌ，ｎ）｝，结果表明，相关因子与叶绿素－ｂ的浓度变化有着较好的吻合。
The systematic analytical method of grey theory was used to study the relationships between chlorophyll-b and 10 environmental factors (temperature, plankton biomass, salinity, dissolved oxygen (Do), pH, phosphate, nitrate, nitrite, Fe, and Mn) in seawater. Samples were collected from Dapeng Bay of the South China Sea, near Yan-tian area of the Shenzhen City. The resulting grey relative values and their permutation indicated that nitrate, phosphate, nitrite and pH had more influence on the chlorophyll-b concentration in seawater than any other factors. A grey model {GM (l, n)} was established to relate chlorophyll-b concentration with four factors among the ten.
