Research on the Evaluation and Screening of Green and Low-carbon Restoration Technologies for River and Lake Buffer Zones and Aquatic Vegetation in the Yangtze River Basin

 Based on the analysis of the restoration technologies of river and lake buffer zones and aquatic vegetation at home and abroad, a technical evaluation index system is constructed from 1four dimensions: technological readiness, economy, pollution reduction and carbon emission reduction, and ecological environment. The Entropy Weight TOPSIS method is applied to evaluate 62 technologies that have been applied in projects. As a result, 9 green and low-carbon technologies for river buffer zone restoration, 9 green and low-carbon technologies for lake buffer zone restoration, 6 green and low-carbon technologies for wetland ecological restoration, and 8 green and low-carbon technologies for aquatic vegetation restoration are screened out. Moreover, radar charts are used to analyze the advantages and disadvantages of these green and low-carbon technologies, and the analysis results can provide guidance for the further optimization and practical application of these technologies.
