Abstract: 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.
