| 中文摘要: |
| 为了探讨扎龙保护区散养与野生丹顶鹤(Grus japonensis)巢址选择的异同,2009年3～5月在扎龙国家级自然保护区内用生境因子测定法对散养丹顶鹤与野生丹顶鹤巢址选择进行比较。独立样本t-检验(independent-samples t-test)结果表明,散养丹顶鹤和野生丹顶鹤在巢址选择中,植被高度、植被密度、巢周围苇丛面积及巢距人为干扰地距离均存在着显著差异。说明野生丹顶鹤对巢址选择具有严格要求,倾向于选择人为活动较少,植被高度较高,植被密度和巢周围苇丛面积较大的生境中筑巢;散养丹顶鹤对生境要求不高。 |
| 英文摘要: |
| To study the differences on nest-site selection of Grus japonensis between semi-captive and wild individuals in Zhalong Nature Reserve,a comparative research was conducted by the factor measurement method in Zhalong Nature Reserve from March to May,2009. Results of Independent-Samples t-test indicated that in the nest-site selection of G. japonensis of Semi-captive and Wild Individuals,difference was found in the heights of vegetation,density of vegetation,the area of reed surrounding nests and the distance of nests from areas of human activities. The results showed that the Wild Individuals of G. japonensis have strong selection to the nest-site. They preferred to feed in the place with less human activity,higher vegetation,bigger the density of vegetation and the area of reed surrounding nests. The Semi-captive Individuals of G. japonensis have weak selection to the nest-site. |
