摘要：黄河三角洲处于海陆交错带,开展地表水化学特征及其影响因素研究,对于认识水化学演化和水体保护具有重要意义。2015年对主要地表水进行样品采集、现场测试和室内分析。结论如下:水体均为碱性,地表水化学空间变异明显,黄河水到近海水体表现为从淡水-微咸水-咸水-卤水的过渡;对照地表水环境质量标准,超标参数为总磷、硝态氮、氯离子和硫酸盐。综合多元统计、Gibbs图及离子关系分析,得出水化学成分主要受自然因素影响,其次为人类活动因素。前者包括水岩相互作用(碳酸盐、方解石和盐岩的溶解)、蒸发结晶和海水入侵混合作用;后者包括生活污水、采油、炼化废水因素以及氨氮硝化作用,导致有机物及氮磷含量升高,需对后者的污染引起足够的重视。
The Yellow River delta is in the sea-land ecotone. Its characteristics of surface water chemistry and influencing factors are important for understanding the chemical evolution of the delta water and water protection.Samples of the major surface water were collected in 2015,and were tested and analzed. Major conclusions are as follows： All the waters are alkalic,and significant spatial variability of water chemistry were found. It showed the fresh water-brackish water-salt water-brine transition from the Yellow River water to the coastal waters. According to the surface water quality standards,total phosphorus,nitrate,chloride and sulphate exceed the standards. Multivariate statistical analysis,Gibbs diagram and ion relationship analysis showed the first identified controlling factors are natural factors,and followed by human activities. The former include water-rock interaction（dissolution of carbonate,calcite and rock salt）,evaporative crystallization and mixing of seawater intrusion. The latter include domestic sewage,oil extraction,refining wastewater factors and the nitrification of ammonium nitrogen,resulting in the high content of organic matter,nitrogen and phosphorus. The impact of pollution caused by human activities should be given attention to.
