利用2008年秋季胶州湾两个航次的调查结果,对该海域营养盐等生源要素的分布特征进行了分析,并通过相关性分析及陆海同步调查数据对其来源做了初步探讨.结果表明,胶州湾秋季两个航次的叶绿素、营养盐、化学需氧量、温度、光照、盐度、溶解氧等各调查要素相应的平面分布趋势基本相同,除盐度和温度外均表现出由河口向离岸逐渐降低的趋势.秋季可能成为胶州湾浮游植物生长限制因子的要素与叶绿素 a 相关性强弱顺序如下(“**”和“*”分别代表置信水平 P=0.01和 P=0.05):活性磷酸盐:0.889(**)、溶解无机氮:0.724(**)、溶解有机氮:0.549(**)、溶解有机磷:0.523(**)、颗粒态氮:0.474(**)、温度:–0.696(**)、活性硅酸盐:0.410(*)、颗粒态磷:–0.191、浊度:–0.096.由相关性分析结果及陆海同步调查结果可初步得出与叶绿素 a 相关性较强的各要素来源如下:化学需氧量、盐度、溶解无机氮、活性磷酸盐、溶解有机氮、溶解有机磷具有明显的陆源输入特征,颗粒态氮以浮游植物新陈代谢产生为主.

In this paper, the distribution and sources of biogenic elements were studied through the analysis of relevance between them based on the investigation results taken in the Jiaozhou Bay during autumn 2008. The re-sults showed that the distribution trends of chlorophyll concentration, nutrients, chemical oxygen demand, tem-perature, light, salinity, dissolved oxygen in the two voyage were basically the same which showed the gradual lowering trend from the outfall to offshore with the exception of salinity and temperature. Potential limiting ones of the phytoplankton growth factors in autumn in Jiaozhou Bay associated with the chlorophyll exhibited the following order(** and * refers to the confidence level(P) of 0.99 and 0.95 respectively): labile phosphate: 0.889(**), dis-solved inorganic nitrogen: 0.724(**), dissolved organic nitrogen: 0.549(**), dissolved organic phosphorus:0.523(**), particulate nitrogen: 0.474(**), temperature: –0.696(**), labile silicate: 0.410(*), particulate phosphorus:–0.191, turbidity: –0.096. Correlation analysis results and results of the river investigation which had been done at the same time of the two voyage can give a preliminary conclusion about the sources of the elements which had tight correlation with the chlorophyll: chemical oxygen demand, salinity, dissolved inorganic nitrogen, labile phos-phate, dissolved organic nitrogen and dissolved organic phosphorus were input from land-based sources and par-ticulate nitrogen is mainly from phytoplankton metabolism.
