Comparative Study of Cl^-Sedimentation Rates in Coastal Areas of Zhanjiang

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.
