摘要
目的 对热带海洋环境氯离子开展立体化观测,掌握热带海洋环境下大气氯离子浓度在空间上的分布规律,为海洋大气环境下装备产品和重大工程服役环境研究提供立体化观测数据支撑.方法 在观测海岸线附近科学选点,采用无人机搭载远程控制大气采样器开展大气氯离子浓度立体化观测,对不同空间高度氯离子浓度分布规律进行分析.结果 成功采集万宁某海岸线附近1 km×300 m×100 m区域1 a以上氯离子浓度数据,通过 GIS 技术分析并建立了氯离子浓度分布三维场,实现了氯离子浓度可视化,并随离海距离、离地高度剖切显示.结论 海南万宁某区域海岸线附近氯离子浓度在冬季最大,夏季最低,且在一定观测范围内,随观测高度增加而先增大、后降低,随离海距离增大而逐渐降低.
Abstract
The work aims to carry out the three-dimensional observation of chloride ion in tropical marine environment to master the spatial distribution law of atmospheric chloride ion concentration in tropical marine environment and provide three-dimensional observation data support for the research of equipment products and major engineering service environment in marine atmospheric environment.Scientific observation points were selected near the observation coastline and unmanned aerial vehicles equipped with remote controlled atmospheric samplers were used to conduct three-dimensional observation of atmospheric chloride ion concentration.Then,the distribution law of chloride ion concentration at different spatial heights was analyzed.The chloride ion concentration data in 1km×300m×100m area were successfully collected.Through GIS technology,a three-dimensional field of chloride ion concentration distribution was analyzed and established,which realized the visualization of chloride ion concentration and the cutting display along with the distance from the sea and the ground height.Near the coast-line of a certain area in Wanning,the concentration of chloride ions is the highest in winter and the lowest in summer.Within a certain observation range,the concentration firstly increases and then decreases with the increase of observation height,and gradually decreases with the increase of distance from the sea.
