摘要

爪哇叶猴（Trachypithecus auratus）是爪哇岛的特有物种，根据世界自然保护联盟（IUCN）的规定，其保护地位处于易受攻击状态。这项研究旨在确定爪哇叶猴在索康邦森林的分布和食物偏好，作为了解生态条件的一部分。研究采用了带状横断面和集中计数法，利用意外取样法对食物的分布进行取样，并通过快速评估记录食物植物的利用数据。结果显示，爪哇叶猴食用的食物种类为 14 种植物，分布在 5 条横断面上的 6 个点。爪哇叶猴喜欢的植物比例为：（Pangium edule）29.4%，（Artocarpus elasticus）17.6%，（Dysoxylum excelsum）11.8%，（Pometia pinnata）8.8%，（Cinnamomum iners）5.9%，其他2.9%。爪哇叶猴在觅食活动中的平均垂直空间利用率为 17.3 米（C 层），占 70.6%。爪哇叶猴树冠空间利用模式的百分比为 CII（36.1%）、CI（19.4%）、BII（13.9%）、AI（11.1%）BII 和 CIII（8.3%）、AII（2.8%）。食物类型和树冠空间是爪哇叶猴在索康邦出现的重要原因。

Ecological conditions of Javan langur (Trachypithecus auratus É. Geoffroy Saint-Hilaire, 1812) in Sokokembang Forest (Central Java, Indonesia) through distribution and food preferences

Javan langur (Trachypithecus auratus) is endemic to Java Island with vulnerable conservation status according to IUCN. The study aimed to determine the distribution and food preferences of Javan langurs in Sokokembang Forest as part of understanding ecological conditions. The research used strip transect and concentration count methods, sampling the distribution of food using accidental sampling and recording data on the utilization of food plants with rapid assessment. The results showed that the types of food consumed by javan langurs were 14 types of plants, which were scattered at 6 points on five transect lines. The percentage of preferred plants was (Pangium edule) 29.4%, (Artocarpus elasticus) 17.6%, (Dysoxylum excelsum) 11.8%, (Pometia pinnata) 8.8%, (Cinnamomum iners) 5.9%, and others 2.9%. The average vertical space utilization of javan langurs during feeding activities was 17.3 m (stratum C) with a percentage of 70.6%. The percentage of tree crown space usage pattern of javan langur in CII (36.1%), CI (19.4%), BII (13.9%), AI (11.1%) BII, and CIII (8.3%), AII (2.8%). Food type and tree crown space are important parts of the presence of Javan langurs in Sokokembang.
