对山东黄河三角洲国家级自然保护区形目鸟类的食性、觅食地质量、食物量与形目鸟类的关系及鸟类在不同觅食地的分布等的研究表明 :形目鸟类单位面积的数量与觅食地底栖生物的生物量呈正相关。并对形目鸟类的觅食地进行了评价
The research on the feeding habits, foraging quality, the relationship between the food quantity and the avian birds and the distribution of birds in different foraging sites in the Yellow River Delta National Nature Reserve in Shandong Province shows that: The number of birds per unit area is positively correlated with the biomass of foraminiferal benthic organisms. The foraging habitat of ostracods was evaluated
