中文摘要：2008年3～5月，采用焦点猴群连续跟踪观察和记录法对金佛山黑叶猴的食性进行了研究。结果表明：黑叶猴春季采食的植物主要有18种，分属8科17属。黑叶猴嗜食灯台树、香叶树、毛叶木姜子、山梨、构树和木姜子，喜食山樱桃、山桃、山桑和野桐。取食部位有叶、芽、嫩枝、花和果实。在日活动节律中，觅食行为有两个高峰期，分别是7:30～9:30和17:00～18:30。在黑叶猴每天的时间分配中，觅食所占的时间比例为21.56%±8.13%。
英文摘要：From March to May in 2008, the feeding habits of Francois’ langur (Trachypithecus francoisifrancoisi) was investigated by focused observation and continuous recording in the Jinfo Mountain Nature Reserve. The results showed Francois’ langur mainly fed on 18 kinds of plants, which belong to 8 families, 17 genera. By index of selectivity (SI), the ranking of food selection was：Cornus controversa, Lindera communis, Litsea mollis, Pyrus ussuriensis, Broussonetia papyrifera , L. wilsoni (SI＞1.5)＞Prunus serrulata, P. davidiana, Morus mongolica, Mallotus japonicus var. floccosus (1.0＜SI≤1.5)＞Salix psammophila, Malus hupehensis, Lasianthus japonicus (0.5＜SI≤1.0)＞Phoebe neurantha, Kerria japonica, Rhododendron simsii, Sorbus folgneri, Maddenia hypoleuca (0＜SI≤0.5), as preferred, favored, edible and anorectic. From March to May, Francois’ langur ate leaves, sprouts, young branches, flowers and fruits. There were two peak-times feeding in the daily activity rhythm of wild Francois’ langur. One was about 7:30～9:30 and the other about 17:00～18:30. The time spent on feeding accounted for 21.56%±8.13% of the daily time distribution.
