【摘要】：随着人类对资源需求的增加,海洋开发的社会价值与经济价值越发重大,但一味追求经济的发展会造成环境不可逆转的破坏。因此,我们要合理规划地发展海洋工程,可持续性地进行沿海工程开发,要充分考虑涉海工程项目所带来的环境影响,做到以可持续为前提、以发展为主线、以高效为特征的海洋资源开发利用。湄洲湾是一个半封闭海湾,港湾三面为山环抱,港内多岛,避风条件良好：无大河流入湾内,泥沙纳量小,是一个常年不冻不淤的天然良港。湄洲湾南岸地区地理位置优越,交通条件便利,发展空间广阔,该地区涉海工程项目众多,对周围环境影响效果显著。本文在进行湄洲湾南岸海域地面、探空以及海陆风环流实验的前提下,以湄洲湾南岸工程主要源强以及监测相关数据为依托,通过对湄洲湾南岸工程项目的环境影响进行研究,可以为该地区沿海工程的可持续发展提供指导,也为其它地区的沿海工程开发提供参考。依此,本文一共分为三个部分进行了相关研究。第一部分针对湄洲湾南岸海域的大气边界层进行分析。通过对中尺度气象模式的介绍以及湄洲湾南岸海域的风向、风速以及逆温层进行观测分析,得出该区域的大气边界层总体特征,为之后的工程污染物扩散、迁移规律研究提供背景支持。第二部分研究的海陆风环流与污染现象关系密切,通过进行观测实验以及结合观测资料对湄洲湾南岸海域进行海陆风环流数值模拟,来进一步研究该区域是否存在海陆风出现所要求的基本海陆温差条件,以及该区域出现的海陆风的特点。第三部分通过AERMOD和CALPUFF模型对湄洲湾南岸海域重点污染源污染物的数值模拟,结合监测值对比分析该区域的地形和气象环境对AERMOD和CALPUFF模型模拟能力的影响,确定更适用于湄洲湾南岸海域乃至沿海区域污染物模拟的空气质量模型。
[Abstract]:With the increase of human resource demand, the social value and economic value of marine development become more and more important, but the pursuit of economic development will cause irreversible damage to the environment. We should develop marine engineering reasonably and carry out coastal engineering development sustainably. We should fully consider the environmental impact of marine engineering projects and take sustainability as the premise and development as the main line. Meizhou Bay is a semi-enclosed bay with three sides of the bay surrounded by mountains and many islands in the harbour. The conditions of avoiding wind are good: no river flows into the bay and the sediment is small. Meizhou Bay south coast area is superior in geographical location, convenient transportation conditions, wide development space, the area involves many sea engineering projects. On the premise of surface sounding and sea-land wind circulation experiments on the south coast of Meizhou Bay the paper relies on the main source strength and monitoring data of the south coast of Meizhou Bay. By studying the environmental impact of Meizhou Bay south coast project, it can provide guidance for the sustainable development of coastal engineering in this area, and also provide reference for coastal engineering development in other areas. This paper is divided into three parts. The first part is the analysis of the atmospheric boundary layer in the south coast of Meizhou Bay. Through the introduction of the mesoscale meteorological model and the wind direction of the southern coast of Meizhou Bay. The wind speed and the inversion layer are observed and analyzed, and the general characteristics of the atmospheric boundary layer in this area are obtained, which are the subsequent engineering pollutant diffusion. The study of migration law provides background support. The second part studies the close relationship between the sea and land wind circulation and pollution phenomenon. Through the observation experiment and the numerical simulation of sea and land wind circulation in the south coast of Meizhou Bay, we can further study whether there are the basic sea-land temperature difference conditions required by the occurrence of sea and land wind in this area. In the third part, the AERMOD and CALPUFF models are used to simulate the major pollution sources in the south coast of Meizhou Bay. The influence of terrain and meteorological environment on the simulation ability of AERMOD and CALPUFF models is analyzed by comparing the monitoring data. The air quality model is more suitable for the simulation of pollutants in the south coast of Meizhou Bay and even the coastal area.
