长江口南支浦东机场圈围外江段营养盐的季节变化
|
摘要
2014年10月-2015年7月对长江口南支浦东机场促淤圈围外江段营养盐进行了季节性调查,分析了总氮、总磷、硝酸盐、亚硝酸盐、氨氮、活性磷酸盐、溶解性无机氮等6项营养盐指标。结果显示该江段营养盐具有明显的季节性变,硝酸盐和氨氮含量春季较高,分别为0.639mg/L和0.098mg/L,亚硝酸盐和总氮含量冬季较高,分别为0.012mg/L和3.418mg/L;活性磷酸盐含量秋季较高,总磷含量夏季较高,含量分别为0.031mg/L和0.322mg/L。调查江段营养指数全年变化范围为2.42-21.99,均大于1,显示水体呈富营养化状态,且存在一定的磷限制。
Nutrient loads in the south branch of the Yangtze River Estuary close to a land-reclamation project of Pudong Airport,were investigated from October 2014 to July 2015.Total nitrogen,total phosphorus,nitrate,nitrite,ammonium,phosphate,and dissolved inorganic nitrogen were analyzed.Nutrient levels varied seasonally.Nitrate and ammonia concentrations were the highest in spring,0.639 and 0.098 mg/L,respectively.Nitrite and total nitrogen concentrations were the highest in winter,0.012 and 3.418 mg/L,respectively.Active phosphate concentration was the highest in autumn and total phosphorus content was the highest in summer,0.031 and 0.322 mg/L,respectively.The annual range in the nutrition index of this section of the river was from 2.42 to 21.99 mg/L,indicating that it was under a eutrophic condition;however,it was phosphorus-limited.
