摘　　要：于2009年12月～2010年2月采用瞬时扫描取样法对贵州麻阳河自然保护区的5个黑叶猴Trachypithecus francoisi猴群以及同域放养的山羊羊群的取食行为进行观察记录,并对两者的取食数据进行比较分析,以期了解该地区黑叶猴与放养山羊在食物资源最为匮乏的冬季的资源竞争关系,为黑叶猴的保护管理提供科学依据。研究结果表明:黑叶猴冬季取食植物67种,放养山羊同期取食植物44种,两者食物重叠26种;对26种重叠食物的采食分别占黑叶猴与放养山羊冬季取食时间的76.2%与22.0%;黑叶猴冬季采食的19种主要食物(>1%冬季采食时间)中,有14种为放养山羊所采食,占黑叶猴与山羊冬季采食时间的71.7%与17.8%;黑叶猴与山羊冬季食物生态位宽度分别为0.68与0.39,两者的冬季食物生态位重叠指数C=0.74。表明贵州麻阳河地区黑叶猴与同域放养山羊在食物最为匮乏的冬季存在较为激烈的食物资源竞争关系。From December 2009 to February 2010, we collected the feeding data of five groups of Franqois＇ langur Trachy- pithecus francoisi and sympatric grazing goats in Mayanghe Nature Reserve via instantaneous scan sampling, aiming to quan- tify the food competition between the langurs and grazing goats in the food-lean season and to provide information for conser- vation. Results indicated that： the langurs fed on 67 floral species while the grazing goats consumed 44 species, with 26 species overlapped between them; the feeding time devoted to the 26 overlapped plants occupied about 76.2% and 22% of the total feeding time of the langurs and grazing goats respectively; 14 out of the 19 major food species （ each accounted for more than 1% of feeding time） of the langurs were consumed by the sympatric grazing goats, and the 14 species accounted for 71.7% and 17.8% of the total feeding records of the langurs and goats respectively; the trophic nich of the langur and grazing goat were 0.68 and 0.39 respectively, and the food niche overlap index between them was 0.74. Findings indicated that there was intense food competition between the langurs and grazing goats in Mayanghe in winter.
