Abstract: Daily energy intake of giant pandas and energy supply of bamboo resources were estimated in Mabian Dafengding Reserve, Liangshan Mountains. On a diet of 12.25 kg(fresh weight) of Qiong zhuea macrophylla leaves and stems, an adult panda could obtain about 15 378 kJ per day in spring, 27 856.2 kJ in summer-autumn, and 20 502.6 kJ in winter. The daily energy in take is just a little bit higher than the daily energy expenditure (14651～16 744 kJ ). The evidence suggests that the panda's nutritional margin of safety is relatively small. Therefore, giant pandas are prone to the environmental pressure. Pandas could utilize only about 123.5 kJ energy supply by Q. macrophylla per square meter. About 0.06 km ² of this bamboo stands could meet an adult panda’s annual energy expenditure.

摘要：

本文对凉山山系马边大风顶自然保护区大熊猫日能量摄入和食物资源能量进行了估算。结果表明, 不同季节大熊猫的日能量摄入各异, 春季为15 378 kJ , 夏秋季为27 856.2 kJ , 冬季为20 502.6 kJ , 约高于日能量支出14 651～16 744 kJ , 营养保险差较小, 对环境的承受力较弱。另外, 环境中每平方米大叶筇竹林能被大熊猫实际利用的能量约为123.5 kJ , 约0.06 km2大叶筇竹林能满足1只成年大熊猫全年的能量消耗。从食物资源蕴藏量来看, 该研究区域大熊猫食物资源十分丰富。
