胶州湾水质及主要营养盐季节性变化分析

于2010年4个季度对胶州湾水质进行了调查,根据单因子污染指数法,利用计算机软件绘制了水质分区图,分析了胶州湾水质的最新状况及不同季节的水质变化情况,同时对胶州湾主要营养盐无机氮和活性磷酸盐的变化进行了分析。调查结果显示,2010年胶州湾水质定性评价为差,无机氮和活性磷酸盐的平均浓度分别为0.393 mg/L、0.018 mg/L,高值区主要分布在胶州湾东北角,无机氮和活性磷酸盐的平均浓度及空间分布随着季节的变化而呈现了一定的变化。

Analysis on Water Quality and Seasonal Changes of Major Nutrients in Jiaozhou Bay

In the four quarters of 2010,Jiaozhou bay water quality was investigated.This paper analyzed the latest water quality changes in different seasons and the changes of Jiaozhou Bay major nutrient salt: inorganic nitrogen and active phosphate.The investigation showed that Jiaozhou bay water qualitative evaluation of 2010 was poor,the average concentration of inorganic nitrogen and phosphate was 0.393 mg/L and 0.018 mg/L respectively,high value zones were mainly distributed in the northeast corner of the Jiaozhou bay,the average concentration and spatial distribution of inorganic nitrogen and phosphate was different in different seasons,and was dynamic.
