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Ca~(2+)、Mg~(2+)、Na~+、K~+、SO_4~(2+)和HCO_3~-与Cl~-以及Br~-与Cl~-的关系作散点图分析.西海岸表层海水Ca~(2+)、K~+、SO_4~(2-)和HCO_3~-与Cl~-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Ca~(2+)K~+和HCO_3~-与Cl~-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.
依據深圳沿海所取31件錶層海水樣品的水化學數據,對主要離子Ca~(2+)、Mg~(2+)、Na~+、K~+、SO_4~(2+)和HCO_3~-與Cl~-以及Br~-與Cl~-的關繫作散點圖分析.西海岸錶層海水Ca~(2+)、K~+、SO_4~(2-)和HCO_3~-與Cl~-的比偏離海水稀釋線,源于其位于珠江河道影響範圍,與珠江水有不同程度的混閤;東海岸錶層海水Ca~(2+)K~+和HCO_3~-與Cl~-的比主要圍繞海水稀釋線波動,錶明沿海錶層海水流動緩慢,受錶層海水蒸髮和噹地沿岸汙染河水排洩的長期纍積影響;靠近深圳灣的5件西海岸海水樣品成分與東海岸錶層海水相似.

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_4~(2-) and HCO_3~-)vs Cl~-,and Br~- vs Cl~- are analyzed.On the western coast,the Ca~(2+),K~+,SO_4~(2-)and HCO_3~- vs Cl~- of surficial seawater deviate from the seawater dilution lines,which are confirmed by the mixture of seawater with fiver water in different ratios under the influence of the Pearl River.On the eastern coast,the Ca~(2+),K~+ and HCO_3~- vs Cl~- of surficial seawater fluctuate around the seawater dilution lines,which are resulted from progressively effect by slow flow and evaporation of the surficial seawater and the discharge of local polluted river waters.The compositions of 5 seawater samples on the western coast near the Shenzhen Bay are similar to those of surficial seawater samples on the eastern coast.
