1976年大熊猫灾难性死亡原因的探讨

大熊猫Ailuropoda melanoleuca(David)是我国一类保护动物,闻名世界。1976年在大熊猫的一些产区由于遭到灾难性的死亡,致使数量急剧下降,有濒临绝灭的危险,现已引起国内多方面的注意。 1976年在甘肃和四川相毗连的岷山山系一支--摩天岭主脉的南北,发生大熊猫灾难性死亡,这主要是由于大熊猫的食物--华桔竹(Fargesia spathacea)大面积开花死亡导致大熊猫食物缺乏而饥饿致死。但是,为什么华桔竹在这个时期内,在大熊猫分布的地方(四川青川、平武、南坪和松潘县、甘肃文县)均有不同程度的开花现象呢?这是一个值得探讨的问题。

A PRELIMINARY DISCUSSION ON THE CAUSE OF THE DISASTROUS DEATH OF GIANT PANDA (AILUROPODA MELANOLEUCA)

The disastrous death of the Giant Panda in 1976 in Southern Gansu was a result from the extensive blossom and drying-to-death of Fargesia spathaeca, which brought the Giant Panda a long-term malnutrition. The blossom of Fargesia spathacea is generally periodical under normal conditions. However, the extensive blossom occurring in Southern Gansu during 1969-1976 as mentioned above was probally related to the anomalies of geophysics and geochemistry, which might be caused by the powerful and recurrent earthquake of its neighbouring area Sungpan-pingwu district, Szechuan, and it may have influenced the regular physiographical activities of Fargesia spathacea. The blossom of Fargesia spathacea was synchronized with the earthquake, a strong structural movement of theearth.
