| 摘 要： | 2005~2006年鸟类的繁殖季节,在吉林省左家自然保护区确定了11块次生林斑块,对次生林斑块的边缘效应对鸟类分布格局的影响进行了研究.结果表明:11块样地面积在10.9~51.2 hm2之间,平均面积为24.8 hm2;鸟类主要分布在0~50和50~100 m两个距离梯度;不同梯度中鸟类的分布在年际间未发生较大波动(P0.05),不同距离梯度的鸟类分布差异很大,达到极显著水平(P=0.00);0~150 m为鸟类的主要分布区域,边缘距离为150 m,次生林斑块中边缘效应存在.

| Abstract: | During the bird breeding seasons between 2005 and 2006,11 patches were investigated by GPS to study edge effects of secondary forest on bird distribution in Zuojia Natural Reserve of Jilin Province,China.The results showed that the average patch area was 24.8 hm2,with a range of 10.9~51.2 hm2;birds mainly occurred in the distance gradient of 0~50 and 50~100 m.There were no significant difference for bird distribution between two years(P>0.05),and significant differences in different distance gradient were v... |
