【摘要】 斑尾榛鸡是我国特产松鸡科鸟类,国家Ⅰ级保护动物.1998～1999年,我们利用卫星遥感技术,结合野外实际调查,在甘肃省莲花山区对斑尾榛鸡的栖息地碎分化状况以及生存现状进行了研究.研究表明斑尾榛鸡在莲花山区是一个隔离种群,其主要栖息地针叶林和针阔混交林呈现严重的碎分化状态,针叶林总斑块数为229个,平均斑块大小为18.0hm~2;针阔混交林的总斑块数为477个,平均斑块大小为39.3hm~2.初步调查显示,在受到严重采伐、栖息地严重碎分化的森林斑块中,仍有斑尾榛鸡生存,但数量很低.我们建议加强对研究地区针叶林的保护,扩大现有的莲花山自然保护区,使之包括冶力关地区的大面积针叶林.更多还原

【Abstract】 The Chinese Grouse is an endemic and endangered bird in China. It inhabits the mountain conifer forest. In 1998 and 1999, using satellite images, we studied the habitat fragmentation situation of the Chinese Grouse at landscape scale at Lianhuashan Mountains in Gansu Province. The forest in our study area has been heavily cut during past 30 years. We found the Chinese Grouse did survive in some poor forest patches where forest been cut for more than 60 percent, however, in very low density. We suggest enlarging the Lianhuashan Natural Reserve to include the Yeliguan area, where most relatively good conifer forest left.更多还原
