摘　　要：2011年3—5月,使用粪便显微分析法对扎龙保护区丹顶鹤求偶期的食性与营养组成进行了研究。结果表明:扎龙保护区丹顶鹤求偶期的食物组成包括9科27种植物,禾本科、莎草科、黑三棱科、蓼科和眼子菜科占取食的主要部分,其中玉米(Zea mays)、芦苇(Phragmites australis)、黑三棱(Sparganium stenophyllum)、糙叶苔草(Carex tristachya)、碱蓬(Suaeda glauca)、马来眼子菜(Potamogeton malaianus)和贝加尔针茅(Stipa baicalensis)是主要食物(占取食植物的88.24%);不同植物的不同营养成分存在显著差异,获取率也显著不同。进一步分析表明,植物的营养成分是影响该时期取食的关键因素之一,丹顶鹤偏好取食粗蛋白含量高、粗纤维含量低的植物。An experiment was conducted to study the feeding habit and nutritional composition of Red-crowned Crane in Zhalong Nature Reserve by microscopic fecal analysis during March-May 2011.Results indicated that the diet composition of Red-crowned Crane in Zhalong Nature Reserve included 27 plant species in 9 families during the courtship period.Gramineae,Cyperaceae,Sparganiaceae,Polygonaceae,and Potamogetonaceae were dominant,among which Zea mays,Phragmites australi,Sparganium stenophyllum,Carex tristachy,Suaeda glauca,Potamogeton malaianus,and Stipa baicalensis were the main foods,accounting for 88.24 percent of all the plants used.A significant difference in nutritional composition was observed between different plants,and the intake rates for the Red-crowned Crane were also obviously different.Further analysis shows that plant nutrients are key factors affecting the feeding habit of Red-crowned Crane during the courtship period.Red-crowned Crane exhibits feeding preference for plants with high content of crude protein and low content of crude fiber.
