| Abstract: |
| 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. |
