大熊猫的放归与保护

根据大熊猫在野外的分布格局，对栖息地的选择及种群生存力的分析，应将大熊猫就地保护，使固有的栖息地的种群得以恢复，并提高其生存值和适应度。另一方面，圈养的大熊猫存活率和净生率都大于野外种群，经过一段时间的增殖，保持其野外生态习性，通过驯化，先在大面积范围内散放，然后放归自然，增加野外种群数量和遗传多样性是可行的。

THE RETURNING TO THE NATURE AND PROTECTION OF GIANT PANDAS

Accoding to the analysis of giant pandas' distribution pattern,habitat selection,population structure and vitality in the wild,it is important that we protect giant pandas in the wild.In this way,the population in the proper habitats can be recovered quickly and developed because of their increasing survival value and fitness.On the other hand,since the breeding and rearing in captivity of giant pandas has developed a great deal,their survival rate and net reproductive rate are both higher than those in the wild.It is also acceptable to set them free in a large area,then let them return to the nature after a period of proliferation,preservation of the ecological habits and characteristics in the wild and domestication,which can increase the wild population and their genetic diversity.
