| 摘 要： | 依据深圳沿海所取31件表层海水样品的水化学数据,对主要离子Ca2+、Mg2+、Na+、K+、SO42-和HCO3-与C l-以及B r-与C l-的关系作散点图分析。西海岸表层海水Ca2+、K+、SO42-和HCO3-与C l-的比偏离海水稀释线,源于其位于珠江河道影响范围,与珠江水有不同程度的混合;东海岸表层海水Ca2+、K+和HCO3-与C l-的比主要围绕海水稀释线波动,表明沿海表层海水流动缓慢,受表层海水蒸发和当地沿岸污染河水排泄的长期累积影响;靠近深圳湾的5件西海岸海水样品成分与东海岸表层海水相似。

| Abstract: | Based on hydrochemical data of 31 surficial seawater samples collected along the coast of Shenzhen,scatter diagrams of major ions(Ca~(2+),Mg~(2+),Na~+,K~+,SO~(2-)_4 and HCO~-_3) vs Cl~-,and Br~-vs Cl~-are analyzed.On the western coast,the Ca~(2+),K~+,SO~(2-)_4 and HCO~-_3 vs Cl~-of surficial seawater deviate from the seawater dilution lines,which are confirmed by the mixture of seawater with river water in different ratios under the influence of the Pearl River.On the eastern coast,the Ca~(2+),K~+ and HCO~-... |
