摘要
本研究利用粪粒对一群滇金丝猴的食物摄食量进行了定量分析,并检验了它们的主要食物类型。通过对笼养滇金丝猴消化能力的测定,建立野外滇金丝猴群摄食量方程;结合数理统计进行分析。结果表明,该猴群在雪季每排下0.49千克混合残留物,即应先食入单子叶植物12.5千克,地衣21.7千克,冷杉叶1.1千克(均指干重值)。对解消假设检验显示,冷杉叶是滇金丝猴的很次要食物。
This study delt with quantitative analysis for diets taken in by a group of Rhinopithecus bieti in wild, and tested its principal types of diets among the residues from its excrements. Through the determination of digestive ability from an individual of R. bieti in captivity, an cquantion about . quantity of diets taken in by wild R. bieti groups was established. The results have indicated that, in this group of R. bieti, Per 0.49 kg residuary compounds excreted must correspond to 12.5 kg of grass belonging to Monocotydoneac, 21.7kg of lichens, but only 1.1 kg of leaves of Abies sp. etc. taken in (all arc dry weights) . These data had been analysed with statistics, and test of null hypothesis indicated that Abies sp. are less important diets than the two above.
