湖库泥沙资源化多目标优化配置研究综述

A Review of Multi-objective Optimal Allocation of Sediment Resources in Lakes and Reservoirs

合理利用泥沙的资源特性,实现泥沙资源优化配置是湖库生态环境治理迫切需要解决的关键问题之一。该文旨在对泥沙资源化及多目标优化配置方法的研究进行综述,总结泥沙资源化的研究现状和分析其发展趋势。首先对泥沙资源优化配置框架的相关研究进行了综述,主要集中于泥沙资源优化配置、泥沙资源化的途径、泥沙管理生态化及优化配置方法等方面,然后分析了目前对于泥沙资源优化配置的理论认识、模型构建及应用、方案评价及决策存在的主要问题,最后探讨了泥沙资源优化配置相关研究未来发展方向。

The rational utilization of the characteristics of sediment resources to achieve the optimal allocation of sediment resources is one of the key problems which needs to be solved urgently for the ecological environmental governance in lakes and reservoirs. This paper aims to review the study on sediment resources and the multiobjective optimization methods,summarize the research status of sediment resources and analyze its development trend. Firstly,relevant researches on sediment resources optimal allocation framework were summarized,which mainly focus on the sediment resources optimal allocation,approach to sediment resources utilization,sediment ecological management and optimal allocation methods. Then the existing problems such as the current understanding on sediment resources optimal allocation theory,model construction and application,evaluation and decision-making were analyzed. Finally the future research direction of sediment resources optimal allocation was discussed.
