空气中氯离子沉积速率的影响因素分析

目的 分析空气中氯离子沉积速率的影响因素。方法 采用灰色关联分析法、pearson相关系数法和spearman相关系数法分析了海南省中东部离海岸线350 m处监测的气温、相对湿度、风速、降雨量、海水有效波高、海水温度与氯离子沉积速率的相关性。结果 3种方法的分析结果一致表明，与氯离子沉积速率的相关性最高的是海水有效波高，而与其他环境因素的相关性交替排序。结论 海水有效波高与氯离子沉积速率呈现显著性正相关，表明海水有效波高越高，氯离子沉积速率越大。

Analysis of Factors Influencing Chloride Deposition Rate in Air

The work aims to analyze the factors influencing chloride deposition rate in air. The gray correlation analysis method, Pearson correlation coefficient method and Spearman correlation coefficient method were used to analyze the correlation among air temperature, relative humidity, wind speed, rainfall, sea water effective wave height, sea water temperature and chloride deposition rate monitored 350 m away from the coastline in the Middle East of Hainan Province. The results of the three methods were consistent, the sea water had the highest correlation with chloride deposition rate, and the correlation with other environmental factors was arranged alternately. There is a significant positive correlation between the effective wave height of sea water and chloride deposition rate, indicating that the higher the effective wave height is, the higher the chloride deposition rate is.
