摘要

根据2008-2015年间共24个航次水质调查资料及人工鱼礁建设情况,分析了活性磷酸盐()、活性硅酸盐()和溶解无机氮(DIN)的分布、人工鱼礁建设的影响及DIN组成特征和营养盐结构的变化。结果表明2008~2015年间,海洋牧场鱼礁区和DIN含量呈现增长趋势,且秋季的浓度高于春、夏两季,而春夏两季含量较为稳定,2010年后浓度秋季高于春夏两季。对照区秋季含量高于春季和夏季,秋季呈递减趋势,春夏变化规律不明显,但与DIN变化与鱼礁区类似,变化幅度均较小于鱼礁区。可见,鱼礁建设明显增加了海洋牧场鱼礁区磷酸盐和无机氮含量,对硅酸盐含量的作用不明显,一直维持在相对稳定的浓度水平。另外,海洋牧场无机氮组成也发生了改变,由2012年前为主要组成变为。营养盐结构分析显示海州湾海洋牧场主要是限制。
According to the data of 24 voyage water quality survey and artificial reef construction in 2008-2015, analysis the distribution of active phosphate, active silicate and dissolved inorganic nitrogen, the effects of artificial reef construction, DIN composition and nutrient structure changes.The results showed that and DIN content increased in the marine reef area during 2008~ 2015, and the concentration in autumn was higher than that in spring and summer,while the concentration of was stable in spring and summer, after 2010 the concentration in autumn is higher than that in spring and summer.The control area concentration of in autumn was higher than that in spring and summer, and decreased in autumn, and the change regularity was not obvious in spring and summer, however, the change of and DIN is similar to that of reef area, and the variation range is smaller than that of reef area.It is obvious that the reef construction obviously increases the content of and DIN in the marine reef area, and the effect on the content is not obvious. The content has been maintained at a relatively stable concentration level.In addition, the composition of inorganic nitrogen in marine rangeland also changed from to in 2012.
