| 中文摘要: |
| 2008年11月至2009年3月,采用样线法、样方法和因子分析法对鄱阳湖国家级自然保护区越冬白鹤(Grus leucogranus)觅食地特征进行了研究。结果表明,白鹤在保护区的分布具有时空动态性,主要受水位和食物的控制;白鹤对不同类型觅食地具有选择性(P<0.05),对沉水植物型觅食地,即以苦草(Vallisneria natans)、黑藻(Hydrilla verticillata)、马来眼子菜(Potamogeton malaianus)为主的沉水植物型生境利用度最大;白鹤各型觅食地各因子的方差分析表明,植被因子具有极显著差异(P<0.001),基底因子和掘食因子具有显著差异(P<0.05);因子分析表明,觅食地选择以取食效率因子为主,其次是基底因子和食物丰富度因子。 |

| From November 2008 to March 2009,the characteristic of the feeding habitat wintering Siberian Crane’(Grus leucogranus) was studied using line transect,plot sampling measurement and factor analysis methods in Poyang Lake National Nature Reserve of Jiangxi Province.We found: the distribution of the Siberian Crane in the Poyang Lake showed spatio-temporal dynamics,mainly affected by the factors of water and food.There isa significant selection of the Siberian Crane on the different feeding habitats(P < 0.05),and the bird favored on the habitat of submerged plants,dominated on Vallisneria atans,Hydrilla verticillata,Potamogeton malaianus.Based on variance and factor analysis,we discovered that there were significant differences in vegetation(P < 0.001),basement and digging food factors(P < 0.05).As to feeding habitat selection of Siberian Crane,the feeding efficiency factor was dominant with basement and food abundance factors followed. |
