基于多目标决策模型的如东近岸浅滩适宜围填规模研究

适宜的围填海规模能够最大限度的协调岸滩围填和海洋资源环境保护的关系。以江苏辐射沙脊海域如东近岸浅滩围填海为例,运用多目标决策理论与方法,综合考虑围填海对动力泥沙环境、海洋生态环境、资源综合开发和社会经济影响,建立围填海适宜规模评价指标体系,构建适宜围填规模评价决策模型。并对该岸段不同的围填规模方案进行计算,据此推荐围堤前沿线位于+5 m的围填海方案是该岸段的适宜围填规模。对围填海适宜规模的研究手段和方法进行了探索和尝试。提出的研究方法及推荐的如东岸段近岸浅滩适宜围填规模可为江苏滩涂资源的开发提供参考。

Study on appropriate scale reclamation of Rudong shoal based on multi-objective decision model

Appropriate reclamation scale can coordinate the relationship between reclamation and protection of marine environment and resources to the maximumextent.Taking Rudong shoal of radial sandy ridges area as an example,an integrated study is made on various aspects of impact caused by reclamation including the dynamic sediment environment,marine ecological environment,comprehensive resource development,society and economy.By using the multi-objective decision theory and methods,an assessment model of appropria...
