厦门西海域环境参数的分布特征

The Distribution Features of Environmental Key Parameters In Xiamen Western Sea

本文以厦门西海域１９９０～１９９２年的环境监测数据为基础，分析总结了厦门西海域环境参数的分布变化特征。通过对水体中ＣＯＤ和无机氮含量变化的分析，指出水体自身污染的趋势以及人为排放的不良影响，并利用聚类分析的手段将西海域划分为７个区域，各区具有不同的环境性质。

Based on the environmental monitoring data from 1990 to 1992,the distributionfeatures of environmental key parameters in Xiamen Western Sea were discussed and concluded,Thetendency to self-pollution in the water and the bad effect of discharge were demonstrated by means ofanalysing the variation of COD and inorganic nitrogen concentration. The result of cluster analysis ledto the study region being divided into 7 areass, of which each had various environmental characters re-spectively.
