We compared the European and eastern Chinese waterbird assemblages and checked whether the effects of human disturbance could be detected in the assemblages' composition. For the different Chinese provinces, we expected to find a negative effect of economic development on the mean bird species mass and on the proportion of bentivorous, piscivorous and insectivorous bird species. We also expected to find relatively fewer large species in the Chinese assemblage. Species rank-abundance curves were relatively similar, but China had significantly more species with smaller body masses. The China assemblage was characterized by relatively higher abundance of heavy-bodied species, contrary to our expectations. Mean bird body mass decreased in China with increasing disturbance and increasing gross domestic product (GDP). For coastal provinces in China the percentage of bentivorous, piscivorous and insectivorous bird species declined with increasing GDP, maybe through the increased use of pesticides or fertilizer.
我们比较了欧洲和中国东部的水鸟组合，并检查了在组合的组成中是否可以检测到人类干扰的影响。对于不同的中国省份，我们预计经济发展对鸟类物种平均质量和食虫、食鱼和食虫鸟类比例的负面影响。我们还预计在中国的组合中相对较少的大型物种。物种等级-丰度曲线相对相似，但中国的物种数量明显较小。中国组合的特点是相对较高的重体物种的丰度，与我们的预期相反。随着干扰和国内生产总值（GDP）的增加，中国鸟类的平均体重减少。对于中国沿海省份，食虫、食鱼和食虫鸟类的比例随着 GDP 的增加而下降，也许是由于使用了更多的杀虫剂或化肥。
