| 摘 要： | 本研究分析了2017年9月(夏季)和11月(秋季)青岛市文昌鱼(Branchidermus fasciatus)水生野生动物市级自然保护区营养盐含量的季节变化和平面分布,并对该海域进行了富营养化评价。研究结果显示,2017年溶解无机氮(DIN)平均含量夏季高于秋季,NO_(2-)N、NH_(4-)N平均含量分别是秋季的1.98倍、1.44倍,而NO_(3-)N和PO_(4-)P平均含量低于秋季,分别是秋季的88.8%和47.6%。夏季DIN总体水平优于海水一类标准值,PO_(4-)P总体水平优于海水一类标准值;秋季DIN总体水平优于海水一类标准值,PO_(4-)P总体水平劣于海水一类标准值。从水平分布来看,夏季海水的DIN浓度分布趋势大致呈核心区实验区缓冲区的趋势;秋季海水的DIN浓度分布呈缓冲区实验区核心区。夏季N/P比值略高于Redfield比值,而秋季N/P比值较低于Redfield比值,DIN相对缺乏。根据潜在性富营养化评价模式,2017年保护区海域夏季和秋季营养水平较低,均属于贫营养水平。
