【摘要】 渤海湾是渤海西部的一个浅水海湾,是渤海的三大海湾之一。随着环渤海区域经济的快速发展,海岸带的高强度开发,渤海湾面临巨大的生态环境压力。研究了渤海湾的水动力特性和水交换;海域水质、富营养化的演变和评价;建立了基于结构方程模型SEM和贝叶斯网络BN相结合的SEM-BN模型,利用遥感资料成功地预报了浮游植物的分布。更多还原

【Abstract】 Bohai Bay is a shallow bay in western Bohai Sea.With the development of economy and the increase of pollutant emission along coastal areas,the coastal ecological environment is facing tremendous pressure.In this paper,hydrodynamic characteristics and water exchange of Bohai Bay was studied;evaluated the evolution of marine water quality and eutrophication;established the SEM-BN ecological model based on Structural Equation Model and Bayesian network;predicted the distribution of phytoplankton using remote sensing data.更多还原
