湿地修复是应用生态学的重要研究内容，湿地修复成效的评价是其中的研究焦点。本研究拟采取空间差异代替时间差异的方法，在黄河三角洲早期修复湿地、晚期修复湿地和未修复自然湿地等3个区域开展鸟类群落多样性和空间分布、鸟类体内重金属积累、湿地重金属空间分布、底栖动物分布及其体内重金属积累等相关研究。以揭示鸟类和重金属空间分布间的关系，探寻湿地重金属环境的指示鸟种，探讨重金属在湿地底质、底栖动物和鸟类之间的富集效应，进而建立湿地修复评价体系，以综合评价湿地生态修复成效。研究结果不仅能丰富湿地修复生态学理论，也可为湿地环境监测和湿地生态修复提供科学依据。

Wetland restoration is important in applied ecology and its research focus is evaluation of restoration effect. We will conduct studies on diversity and spacing distribution of bird community, heavy metals accumulation in body of birds, spacing distribution of heavy metals in wetland, distribution of zoobenthos and heavy metals accumulation in body of zoobenthos in order to reveal the relation of spacing distributions between birds and heavy metals in wetland, seek out indicative bird species of wetland with heavy metals and discuss mechanism of concentration from wetland bottom, zoobenthos to birds, using method for replacing time difference in space difference in early restored wetland later restored wetland and natural wetland in Yellow River Delta . Further more, we will establish evaluation system for wetland restoration to evaluate the effects of wetland restoration comprehensively basing on above results. The research results can not only enrich the theory of wetland restoration ecology, but also provide scientific basis for wetland environment monitoring and wetland restoration.
