摘　　要：为解决巢湖流域防洪蓄洪能力不足、水体富营养化和生物多样性偏低等问题,本研究提出了一个创新的基于自然的解决方案(NbS),以十八联圩生态湿地蓄洪区为例,实现了调蓄洪水、水质净化、生物多样性保护和农业种植等多项目标。该项目采用多田湿地恢复、沼泽湿地恢复和林草湿地恢复等多种措施,并结合生态渗滤岛技术和小微湿地技术,以构建多目标的生态湿地蓄洪区。通过将南淝河水引入湿地系统,实现分洪蓄洪功能,改善入湖水质,提升了十八联圩区域生物多样性和生态系统稳定性。本研究为类似生态湿地的设计和管理提供了有价值的参考,展示了在生态修复和水资源管理领域的创新方法。This study proposes an innovative Nature-based Solutions(NbS)to address the insufficient flood control and storage capacity,eutrophication of water bodies and low biodiversity in the Chaohu lake catchment.Shibalianwei ecological wetland was taken as an example of flood buffer zone,which achieves a number of objectives such as flood regulation,water purification,biodiversity conservation and agricultural cultivation.The project adopts various measures such as multi-field wetland restoration,marsh wetland restoration and forested wetland restoration,and combines ecological percolation island technology and and small micro-wetland technology in order to construct a multi-objective flood buffer zone of the ecological wetland.The project realized the function of flood diversion and storage by introducing water from the Nanfei river into the wetland system,improved the quality of water entering the lake,enhanced the biodiversity and ecosystem stability of the Shibalianwei.This study provides a valuable reference for the design and management of similar ecological wetlands,demonstrating an innovative approach in the field of ecological restoration and water management.
