白头叶猴环境生态的研究──白头叶猴的野生食性

ENVIRONMENTAL ECOLOGICAL STUDY OF WHITE-HEADED LANGUR──RESEARCH ON FIELD-DIET OF WHITE-HEADED LANGUR

对野生条件下若干群白头叶猴进行食性考察．以不干扰白头叶猴正常觅食习性为前提，以观察记录白头叶猴采食动作和食遗物食迹为根据，研究白头叶猴的主要食物来源、采食植物种类和部位、采食行为特点．结果表明：白头叶猴喜食植物至少有３０种，分属２７个植物属和１８个植物科．采食部位分别有叶、花和果．白头叶猴采食习惯于攀扶采摘、攀扶持嚼、折枝握扯、折枝持嚼和拔枝咬嚼５种进食型式．白头叶猴的饮水来源、食源和蔽荫栖息与石山森林环境保护具有极重要相关．

The feeding habits of some groups of the white-headed langur in wild state was observed and studied.According to the principle of not to distract the behaviour of white-headed langur often looking for food and the observing records of the behaviour of white-headed langur eating plant and the trace of white-headed langur eating rest food,studied that the main resource of white-headed langur often eating plant and the plant's species or plant's parts of white-headed langur often eating and the behaved characteristic of whiteheaded langur eating.The results show that the plants of white-headed langur often eating are not less than thirty species,belonging to 27 genera and 18 families.The plant's parts of white-headed langur often eating are leaf,flower'and fruit.The eating ways of white-headed langur embrace five types,elimbing and picking or climbing and chewing or breaking branch and pulling leaves or breaking branch and chewing or pulling branch and chewing with the front limbs.The sources of drinking water and eating plant and under perch of white-headed langur has a direct bearing on the environmental protection f of forest in limesstone muuntant.
