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 2 0 0 1年DIN(无机氮总 -N)含量的变化范围是 2 0 1 2～ 136 8 1μg dm3,PO4 -P含量的变化范围是 9 2～ 1190 0 μg dm3。从 1999年至 2 0 0 0年 ,DIN含量的变化范围是 74～ 2 0 6 8μg dm3,PO4 -P含量的变化范围是 70 9～ 182 5 μg dm3。同时该文将地下水中氯离子作为海水入侵指标 ,根据氯离子背景值确定出海水入侵氯含量指标值。
【英文摘要】 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 results showed that content of DIN for 2001 year ranges from 201.2μg/dm3 to 1368.1μg/dm3 and content of PO 4-P ranges from 9.2μg/dm3 to 1190.0μg/dm3, in Xiamen Island. From 1999 to 2000 year,in Zengcuoan village, DIN ranges from 74μg/dm3 to 2068μg/dm3 and PO 4-P ranges from 709μg/dm3 to 1825 μg/dm3.Chlorion was used as..
