中文摘要：目的研究热带海洋大气环境中SVCl^-的影响因素及变化规律。方法在湛江市临海陆地区域,通过湿烛法采集SVCl^-样品,利用Cl^-选择电极分析样品Cl^-含量,获得SVCl^-。分析热带海洋大气环境SVCl^-与地理位置、温度、湿度等环境因素的相关性。结果地理位置对SVCl^-影响显著,在风大、浪高海区的临海区域,SVCl^-是风小、浪平的湾内临海区域的1~7倍。随距海距离的增加,SVCl^-逐渐下降,距海距离50 m处的SVCl^-是距海距离200 m处的7倍左右。温湿度对SVCl^-影响显著,在低温干燥的冬季,温度升高,SVCl^-增加;湿度升高,SVCl^-降低。在温度逐渐升高、湿度逐渐增大的春季,在距海距离150 m内,SVCl^-的变化幅度较小,且与温度、湿度变化的相关性不大;在距海距离200 m处,SVCl^-随温度升高、湿度增大而增大。结论相距较近但处于不同临海位置区域的氯离子沉降速率有可能相差较大,氯离子沉降速率受临近海区海况条件,盛行风向等因素影响。

外文摘要：To study the influencing factors and change rule of SVCl^-in tropical marine environment.SVCl^-samples are collected by the wet candle method in the coastal areas of Zhanjiang.SVCl^-is gained from Cl^-content by ion-selective electrode analysis.The correlation isanalyzed between SVCl^-in tropical marine environment and the environmental factors(such as geographical location,temperature,and humidity).Geographical location has obvious influence on SVCl^-.SVCl^-of the coastal areas with wind and waves is about 1~7 times that of the coastal areas without wind and waves,and SVCl^-decreases with the increasing distance from the coastline(SVCl^-of the location 50 m away from the coastline is 7 times that of the location 200 m away from the coastline.Temperature and humidity have obvious influence on SVCl^-,too:SVCl^-increases with the increasing temperature and the decreasing humidity in cold and dry winter;in spring when temperature and humidity increase,within 150 m away from the coastline,the correlation is not significantly between SVCl^-and temperature and humidity,and SVCl^-changes little,but SVCl^-increases with the increasing temperature and humidity within 200 m away from the coastline.SVCl^-s of the locations that are close to each other and face different sea areas could be quite different.SVCl^-s sedimentation rates are affected by the adjacent sea state and the direction of the prevailing winds.
