大熊貓是熊科,據考證,大熊貓的古代名稱有貘、白豹、虞等。在200多萬年前的更生世早期,到100萬年前的更生世中晚期,大熊貓已廣布于我國南半部,組成了大熊貓-劍齒象動物群,該動物群的許多種已經絕滅,而大熊貓卻一直活下來,因此大熊貓有“活化石”之稱。

大熊貓的生長環境:

大熊貓棲于中國長江上游的高山深谷,為東南季風的迎風面,氣候溫涼潮濕,其濕度常在80%以上,它們是一種喜濕性動物。大熊貓生活的6塊狹長地帶,包括岷山、邛崍山、涼山、大相嶺、小相嶺及秦嶺等幾大山系,橫跨川、陜、甘3省的45個縣(市),棲息地面積達20000平方公里以上,種群數量約1600只,其中80%以上分布于四川境內。它們活動的區域多在坳溝、山腹洼地、河谷階地等,一般在20°以下的緩坡地形。
