生态湿地蓄洪区恢复与设计——以十八联圩湿地为例

Restoration and Design of Ecological Flood Regulating and Storage Wetland—A Case Study of Shibalianwei Wetland

摘要: 以生态湿地蓄洪区——十八联圩湿地为例，针对蓄洪区进水长期高水位运行后湿地植被受损与生态功能退化问题，旨在解决湿地植被恢复困难的难题。采用“以自然恢复为主，人工修复为辅”为导向的技术路径，设计了以下策略：1) 基础调查，锁定恢复重点；2) 水力修复，重塑多样生境；3) 基底修复，激活土壤活力；4) 植被恢复，乡土耐淹物种的精准配置。湿地植被恢复效果预期较好，可为其他类似圩田湿地植被恢复提供借鉴。

Abstract: Taking the ecological flood regulating and storage wetland—Shibalianwei wetland as a case study, this research addresses the challenges of vegetation degradation and ecological function loss caused by prolonged high-water levels following flood retention. Aimed at overcoming the difficulties in restoring wetland vegetation, a technology-driven approach prioritizing natural recovery supplemented by artificial restoration was adopted. The main strategies include: 1) Baseline surveys to identify key restoration targets; 2) Hydrological restoration to reshape diverse habitats; 3) Substrate remediation to reactivate soil vitality; 4) Vegetation restoration through precise allocation of native flood-tolerant species. The wetland vegetation is expected to recover effectively, offering a valuable reference for the restoration of similar polder wetlands elsewhere.
