| 摘 要： | 2002年8月，在黄海北部大连湾棉花岛海域发生的丹麦细柱藻赤潮中，跟踪测定了赤潮生消过程的生物数量及各环境要素。用主成分分析的方法，分析该海域丹麦细柱藻赤潮与环境因子的相关关系。结果表明，pH、叶绿素a、水色、DO、活性磷酸盐、COD以及透明度是指示(影响)赤潮生物细胞总量的关键因子。

| Abstract: | The phytoplankton densities and related water quality parameters were monitored in the waters near Mianhua Island in Dalian Bay of north Yellow Sea during the Leptocylindrus danicus blooming period in August of 2002. The correlativity between red tides and the ambient sea- water factors was studied by means of the principal components analysis. Results indicated that the key instructive factors of the total numbers of phytoplankton are pH, chlorophyll-a, water color, dissolved oxygen (DO), available phosphate, chemical oxygen demand(COD) and light penetration measured by the Secchi disc. |
