基于RRM的沿海港口生态风险评估方法研究

摘要

Based on Relative Risk Model (RRM), by considering the properties of coastal port construction and operation, the construction, ship activities and comprehensive pollution are selected as three risk sources to carry out the risk impact analysis of the organisms which live in three kinds of biological circumstances, i.e. harbor landside area, intertidal zone and offshore seawater. In addition, the ecological risk assessment model specially for coastal ports is built to realize the quantitative comparison of various ecological risks during the construction and operation of coastal ports, provide a reference for identifying main risk sources and controlling the risks.%基于相对风险模型(Relative Risk Model,RRM),针对沿海港口建设和运营中的特性,选取施工建设、船舶活动和综合污染作为风险源,对港区陆域、潮间带和近海水体三种生境中的生物进行风险影响分析,建立了适合沿海港口的生态风险评估模型.模型实现了沿海港口施工期和运营期各种生态风险的定量化比较,为港口经营者对主要风险源的确定和风险管理提供参考依据.
