深圳大亚湾海域无机氮的组成、分布特征及其富营养化状况再探
|
摘要
以2017年对深圳大亚湾海域4个航次的调查数据为基础,分析不同季节无机氮中亚硝酸盐氮、硝酸盐氮和氨氮的组成比例,讨论不同季节无机氮在大亚湾海域的分布情况。运用营养状态质量指数法(NQI)和潜在性富营养化评价法评价海域富营养化状况,并利用叶绿素a与环境指标的相关性分析研究海水富营养化的环境驱动因子。结果表明,海域内无机氮的主要组成部分为硝酸盐氮和氨氮,受丰水期带来陆源污染的影响呈现明显的季节性变化;海域整体富营养化水平为贫营养状况,且在春季和冬季海域内呈现氮限制状态;富营养化的主要环境驱动因子为化学需氧量和氨氮。
Based on the survey data of 4 voyages in Daya bay of Shenzhen in 2017,the proportion of nitrite nitrogen,nitrate nitrogen and ammonia nitrogen in inorganic nitrogen in different seasons was analyzed. The distribution of inorganic nitrogen in different seasons was discussed,and the eutrophication status of the sea area was evaluated by nutritional status index and potential eutrophication evaluation. Environmental driving factors of eutrophication in sea water were analyzed. It showed that the main components of inorganic nitrogen in the sea area are nitrate nitrogen and ammonia nitrogen. They were seasonally influenced by the land sources especially in wet season. The overall eutrophication level is poor,and the nitrogen limitation status of the sea area occurred in spring and winter. The main environmental driving factors of eutrophication are chemical oxygen demand and ammonia nitrogen.
