| 目的 研究热带海洋大气环境中不同地貌下氯离子沉积速率的分布规律及主要影响因素。方法 通过挂片法采集万宁地区的氯离子沉积速率，并分析离海距离、地形地貌对氯离子沉积速率的影响，以及其与海水因素、自然环境因素间的相关性。结果 近海开阔区域氯离子沉积速率受离海距离和地貌的影响显著，在300 m处降低至90 m处的1/3左右，地貌的变化导致同一距离点处的氯离子沉积速率相差30倍。另外，高的海水有效波高、风速和东风占比使春季氯离子沉积速率高于夏季。结论 不同地貌下的氯离子沉积速率均与海水有效波高、风速间呈较强的正相关性。 |

| The work aims to investigate the distribution and major effect factors of the chloride deposition rate in tropical marine atmospheric environment under different geomorphology. The deposition rate of chloride ions near the coastline in Wanning was observed by piece-hanging method, and the effects of the distance from the coastline, topography and geomorphology on the deposition rate, as well as the correlation coefficients between the deposition rate and the factors of seawater or natural environment were analyzed. The result showed that the chloride deposition rate in open offshore areas was significantly affected by distance from the coastline and geomorphology. The chloride deposition rate at 300 m decreased to about 1/3 of that at 90 m. Meanwhile, the change of geomorphology lead it a 30-fold difference at the same distance point. Additionally, high effective wave height, wind speed and easterly wind proportion made the chloride deposition rate higher in spring than in summer. In conclusion, there is a strong positive correlation between the chloride deposition rate under different geomorphology and the effective wave height of seawater and wind speed. |
