文档介绍：厦门岛地下水中营养盐含量及***含量指标的确定郭占荣黄奕普蔡明刚刘广山(厦门大学海洋与环境学院福建·厦门 361005 ) 提要该文以厦门岛地下水为研究对象,研究了地下水中营养盐含量的空间分布和变化。结果表明 2001年 DIN (无机氮总- N )含量的变化范围是 2011 2~ 13681 1 μgΠ dm 3, PO 4- P含量的变化范围是 91 2~ 11901 0 μgΠ dm 3。从 1999年至 2000年,DIN含量的变化范围是 74~ 2068 μgΠ dm 3,PO 4- P含量的变化范围是 709~ 1825 μgΠ dm 3。同时该文将地下水中***离子作为海水入侵指标,根据***离子背景值确定出海水入侵***含量指标值。关键词地下水营养盐***离子厦门岛 Nutrition Content and Indicator Value of Chlorion for Groundwater in Xiamen Island Guo Zhanrong Huang Yipu Cai MinggangLiu Guangshan (Oceanography and Environment School ,Xiamen University ) Abstract The paper takes the groundwater as research object in Xiamen Island. Regional distributions of the nutrition content (NH 3- N、 NO 2- N、 NO 3- N and PO 4- P )in the groundwater are studied. The re2 sults showed that content of DINfor 2001 year ranges from2011 2 μgΠ dm 3to 13681 1 μgΠ dm 3and content of PO 4- P ranges from91 2 μgΠ dm 3to 11901 0 μgΠ dm 3, in Xiamen Island1 From1999 to 2000 year ,in Zengc2 uoan village , DIN ranges from 74 μgΠ dm 3to 2068 μgΠ dm 3and PO 4- P ranges from 709 μgΠ dm 3to 1825 μgΠ dm 31 Chlorion was used as an indicator of seawater intrusion and the index value of 200mgΠ dm 3for seawater intrusion was mended1 The research results are significant for further studying ,drainage of nutrition groundwater to the sea and for identifying the seawater intrusion1 Keywords groundwater ; nutrition ;chlorion ;Xiamen Island 作者简介
