Waterbird diversity is one of the most important indicators for monitoring wetland quality. However, the increasing intensity of reclamation activities in recent decades caused the change of habitat landscape along coasts, which could affect the diversity of wintering waterbirds. Our study tried to investigate how reclamation history and post‐reclamation habitats influence the species richness, species abundance, and Shannon–Wiener diversity of wintering waterbirds along Yancheng coastal wetlands. A total of 68 waterbird species were recorded and the abundance pattern of wintering birds changed from 2009 to 2013. Species richness and abundance of wintering waterbirds varied in the different reclamation histories. Most importantly, the general linear mixed model highlighted the importance of reclamation history, post‐reclamation habitat type, and their interactions for shaping both species abundance and Shannon–Wiener diversity of wintering waterbirds, but these variables did not affect the species richness of waterbirds. Furthermore, the random forest results also showed a positive association between reclamation history with species richness, species abundance, and Shannon–Wiener diversity of wintering waterbirds. Moreover, three post‐reclamation habitat types, Suaeda glauca, bare flat, and fish pond, played important roles for wintering birds. Our results highlighted that reclamation history, post‐reclamation habitats, and their interactions determined waterbird diversity. Given the growing threats to wetland ecosystems from reclamation activities, further research should find a balance between coastal reclamation and waterbird biodiversity conservation.

越冬的水鸟多样性对黄海沿岸开垦历史和开垦后栖息地的响应。
水鸟多样性是监测湿地质量的最重要指标之一。然而，近几十年来开垦活动的强度增加导致沿海栖息地景观的变化，这可能影响越冬水鸟的多样性。我们的研究试图调查开垦历史和开垦后的生境如何影响盐城沿海湿地越冬水鸟的物种丰富度，物种丰富度和香农-维纳多样性。从2009年到2013年，总共记录了68种水鸟物种，并且越冬鸟类的丰度模式发生了变化。越过不同的开垦历史，越冬水鸟的物种丰富度和丰富度也有所不同。最重要的是，一般线性混合模型强调了开垦历史，开垦后栖息地类型，及其相互作用对越冬水鸟的物种丰富度和Shannon-Wiener多样性的影响，但这些变量并未影响水鸟的物种丰富度。此外，随机森林结果还表明，开垦历史与越冬水鸟的物种丰富度，物种丰富度以及香农-维纳多样性之间存在正相关。此外，有三种填海后的栖息地类型，裸露的浅滩和鱼塘对越冬鸟类起着重要作用。我们的结果表明，开垦历史，开垦后的栖息地及其相互作用决定了水鸟的多样性。鉴于开垦活动对湿地生态系统的威胁越来越大，进一步的研究应在沿海开垦和水鸟生物多样性保护之间找到平衡。
