大熊猫出现于更新世初期,兴旺繁荣于更新世中期,曾广泛分布于我国南部、中部、西南,向北直达北京周口店等16个省市,南至缅甸北部。后来由于第四纪的冰川袭击和人为活动的影响,大片森林毁灭后,使它们失去了赖以生存的环境,引起了种群的衰败,故孑遗至今数量稀少,成为我国特产的古老珍稀动物。现仅分布在四川盆地西北部,和与四川毗邻的甘肃文县、陕
The giant panda appeared in the early Pleistocene and thrived in the middle Pleistocene. It was widely distributed in 16 provinces and cities such as southern China, central China, southwest China, northward to Beijing Zhoukoudian and south of Myanmar. Later, due to the impact of Quaternary glaciers and human activities, the destruction of the vast forests caused them to lose their living environment and caused the population to decline. Therefore, the number of rare and ancient monuments has become so small that they have become rare animals of ancient China. Now only distributed in the northwestern Sichuan Basin, and adjacent to Sichuan, Gansu Wenxian, Shaanxi
