摘　　要：城市建设、农业开垦等人类活动影响导致湿地面积锐减、生态功能退化及生物多样性丧失,严重威胁到生态安全与区域可持续发展。湿地的保护与恢复得到国内外学者的广泛关注。区域尺度上的湿地恢复适宜性空间量化评估,有利于降低湿地恢复的复杂程度和恢复成本。本文以三江平原为研究对象,通过对土壤、植被、水文、地形等自然影响因子和土地利用年限、利用强度等社会经济因子的分析,揭示影响湿地恢复适宜性的关键因素,并对湿地恢复适宜性进行评价,确定三江平原恢复可能性高的关键区,以指导三江平原退化湿地的恢复。对三江平原湿地的恢复优先性评价,将有效促进我国北方内陆湿地保护与恢复的研究进展,在此基础上建立湿地恢复优化网络可为湿地管理者和决策者提供科学的参考,同时也为湿地恢复潜力评估和恢复策略的制定提供基本体系框架。The impacts of human activities such as urban construction and agricultural reclamation lead to the sharp decrease of wetland area,the degradation of ecological function and the loss of biodiversity,which seriously threaten the ecological security and regional sustainable development.Wetland protection and restoration has been widely concerned by scholars at home and abroad.The spatial quantitative assessment of wetland restoration suitability at regional scale is helpful to reduce the complexity and cost of wetland restoration.Taking Sanjiang Plain as the research area,integrating natural(soil,vegetation,hydrology,topography,etc.)and socio-economic factors(land use,years and utilization intensity),the key factors affecting wetland restoration suitability were revealed,and the wetland restoration suitability was evaluated to determine the restoration priority areas with high restoration possibility,so as to guide the the wetlandrestoration of Sanjiang plain.The prioritization of wetland restoration in Sanjiang Plain will effectively promote the research progress of wetland protection and restoration in northern China.On this basis,the establishment of wetland restoration optimization network can provide scientific reference for wetland managers and decision makers,and also provide a basic system framework for potential assessment and strategy formulation of wetland restoration.
