【摘要】 随着社会经济的发展和城市化的加快，潟湖已成为人类水资源利用的组成部分。受大量生活污水和工业废水排出以及人类活动等影响，我国大部分湖泊受到不同程度的污染。湖泊水生态数值模拟可以快速、精确地建立湖泊水动力，分析水动力特征和变化规律，为湖泊水环境保护工作提供科学依据，为环境管理和监测部门提供水质现状和模拟预测分析基础，以便更好地进行科学决策。研究了湖泊在连通情况下的水动力和盐度的分布，进而分析工程对水生植物的影响情况，为海南陵水县双湖（新村港和黎安港的两大潟湖）规划的科学决策提供依据。同时，为相关的潟湖数值模拟研究提供参考。更多还原

【Abstract】 With the development of social economy and acceleration of urbanization, the lagoon has become a part of human water resources utilization. Because of the influence of domestic sewage and industrial wastewater discharged and human activities, most lakes are polluted in different degree. Numerical simulation of lake water ecology could quickly and accurately establish lake hydrodynamic model, analyze hydrodynamic characteristics and variation rules, provide scientific basis for lake environmental protection work, and provide the basis for environment management and monitoring departments to provide water quality status quo and simulation prediction analysis, so as to make better scientific decisions.The hydrodynamic and salinity distribution of the lakes under the condition of connectivity were studied, and furthermore the impact of the project to the aquatic plants was analyzed to provide a basis for scientific decision-making of the "Ling Shui County double lakes"(the two lagoons of Xincun Port and Li’an Port) connectivity project in Hainan Province. It can provide a reference for the numerical simulation of lagoons.更多还原
