在水利工程建设的过程中,蓄水水位的提升会对沿岸周边的农田造成侵蚀,不仅影响周边生态环境与耕地,还会造成生态迁移人口增加,抬田工程是解决这一系列问题的有效途径。如今已有的对抬田工程研究偏重于技术及意义,本文通过科学合理的设计,运用成本效益分析方法,对比分析抬田工程项目和传统生态移民项目,并构建决策模型,进一步改进现有的抬田工程经济决策方案。为抬田工程的实施提供更合理的依据,便于抬田工程的推广应用。 In the process of water conservancy construction, agricultural water level will enhance the surrounding coastal erosion caused not only affect the surrounding environment and farmland, but also cause ecological migration of population increase, lifting the field project is an effective way to solve this set of problems . Today, the existing engineering research emphasis on lifting the field of technology and significance of this paper, scientific and rational design, the use of cost-benefit analysis, comparative analysis of lifting the field projects and traditional ecological migration project, and build decision-making model to further improve the existing Carrying out the project of economic decision-making program. To carry out the implementation of the project to provide a more reasonable basis for facilitating the promotion and application of the project.
