黄河三角洲自然保护区湿地生态恢复的原理、方法与实践

黄河三角洲自然保护区以河口新生湿地生态系统为主要生态类型,具有年轻性、脆弱性、不稳定性等生态特点,在自然条件和人为因素的双重影响下,导致部分区域生态恶化和退化。2002年黄河三角洲湿地自然保护区开始实施湿地生态恢复工程,在对湿地生态系统论述的基础上,对自然保护区湿地生态恢复进行了总结,分析了湿地生态恢复的生态背景、湿地退化的原因,论述了实施生态恢复的目的、原理、方法、工程设计及效果评估。

Theory,Methodology and Practices of Wetland Ecological Restoration in Yellow River Delta Nature Reserve

Newly-formed wetland is the main ecosystem type of Yellow River Delta Nature Reserve featured with young-age, frangibility and instability. Influenced by both natural conditions and human activities, some areas of the wetland are ecologically deteriorated and degraded. A wetland restoration project has been carried out since 2002. Based on analysis of newly-formed wetland ecosystem, this paper tries to summarize experiences in wetland ecosystem restoration and to analyze ecological conditions, causes for degradation. The objectives, principles, project design and effect evaluation of the restoration project were described
