【摘要】 1996—2012年,采用样线法、样方法、访问法和野外跟踪观察法对灰胸竹鸡的迁移、扩散、种群自然恢复进行研究。研究结果表明,灰胸竹鸡由1996年两个分布点、50只个体、初始分布面积250 km2的小种群,经过16年的迁移扩散恢复到29个分布点、990只个体、分布面积1 345 km2的大种群,扩散距离达到103 km,遍布海拔500~1 650 m之间,栖息地类也由3类发展到6类。更多还原

【Abstract】 From 1996 to 2012,the authors adopted fixed line transect,tracking and visiting method in the research on bambusicola thoracica’s migration,diffusion and population recovery. In 16 years’ migration diffusion recovery,the population of bambusicola thoracica has developed from 2 distribution points,50 individuals,initial distribution area of 250 km2in 1996 to a large population of 29 distribution points,990 individuals,1 345 km2. The diffusion distance reached 103 km,and the distribution elevation between 500 and1 650 m,the habitat class from class 3 to class 6.更多还原
