【摘要】 【目的】海南长臂猿生境供给是种群发展的瓶颈，了解海南长臂猿现有栖息地的植被组成及其分布状况，为促进种群恢复提供科学依据。【方法】以海南长臂猿栖息地植被为研究对象，以0.5 km网格的方式对栖息地植被进行调查，得到物种和环境数据。并利用多元回归树方法对栖息地植被进行分类，再根据《中国植被》和《海南植被志》的分类原则，以优势种原则划分和命名群系，得到海南长臂猿栖息地植被类型，最后再结合遥感影像，利用ArcGIS软件绘制海南长臂猿栖息地植被群系分布图和海南长臂猿栖息地食源植物群系分布图。【结果】1）海南长臂猿栖息地天然林植被划分为热带低地雨林、热带山地雨林、热带针叶林、热带云雾林这4个植被型，分别包含13、17、1、1个群系，合计32个群系。主要优势群系有：鹅掌柴-水锦树-黄心树群系（Form. Schefflera heptaphylla-Wendlandia uvariifolia-Machilus gamblei）、厚壳桂-厚皮香八角-陆均松群系（Form. Cryptocarya chinensis-Illicium ternstroemioides-Dacrydium pectinatum）、厚壳桂-白颜-黄叶树群系（Form. Cryptocarya chinensis-Gironniera subaequalis-Xanthophyllum hainanensis）、海南杨桐-思茅松-鹅掌柴群系（Form. Adinandra hainanensisPinus kesiya-Schefflera heptaphylla）。2）海南长臂猿栖息地食源植被划分为热带低地雨林、热带山地雨林这2个植被型，分别包含8、6个群系，共14个群系。主要优势群系有：厚壳桂-黄叶树-油丹群系（Form. Cryptocarya chinensis-Xanthophyllum hainanensis-Alseodaphne hainanensis）、海南杨桐-鹅掌柴-细齿叶柃群系（Form. Adinandra hainanensis-Schefflera heptaphyllaEurya nitida）、鹅掌柴-橄榄-禾串群系（Form. Schefflera heptaphylla-Canarium album-Bridelia balansae）。3）在海南长臂猿栖息地食源植被上，海南长臂猿5个家族群的食源植被类型丰富度依次为：B家族群（10种）>A家族群（9种）>C家族群（7种）=D家族群（7种）=E家族群（7种）。【结论】海南长臂猿栖息地主要以热带山地雨林和热带低地雨林植被型为主，植被组成相对丰富，但不同家族群的食源植物类型组成有较大差异，尤其是A、B、C、D 4个家族群与E家族群之间的食源植被差异最明显，A、B、C、D 4个家族群栖息地内热带山地雨林和热带低地雨林植被的面积比例大致持平，植被类型相对丰富，而E家族群所有植被类型均属于热带低地雨林，植被类型相对单一。本研究可以为海南长臂猿现有栖息地和潜在栖息地的植被恢复提供重要参考价值，有利于改善海南长臂猿生境质量，促进海南长臂猿物种恢复和发展。更多还原

【Abstract】 【Objective】Habitat supply of Hainan gibbons is a bottleneck for population development. Understanding the vegetation composition and its distribution in the existing habitat of Hainan gibbons provides a scientific basis for promoting population recovery.【Method】Hainan gibbon habitat vegetation is taken as the research object, and the vegetation in the habitat is investigated with a0.5 km grid to obtain species and environmental data. The habitat vegetation is classified by using multiple regression tree(MRT)method, and then according to the classification principles of China Vegetation and Hainan Vegetation, the formation is divided and named according to the principle of dominant species, so as to obtain the vegetation type of the habitat of Hainan gibbon. Finally,combined with remote sensing images, The distribution map of vegetation groups in Hainan gibbon habitat and the distribution map of food plant vegetation groups in Hainan gibbon habitat were drawn on the map by using ArcGIS software. 【Result】1) The forest vegetation in the habitat of Hainan gibbon are divided into 4 vegetation types: tropical lowland rain forest, tropical mountain rain forest, tropical coniferous forest, tropical cloud forest, including 13, 17, 1 and 1 formations respectively, with a total of 32 formations.The main dominant groups are: Form. Schefflera heptaphylla-Wendlandia uvariifolia-Machilus gamblei, Form. Cryptocarya chinensis-Illicium ternstroemioides-Dacrydium pectinatum, Form. Cryptocarya chinensis-Gironniera subaequalis-Xanthophyllum hainanensis,Form. Adinandra hainanensis-Pinus kesiya-Schefflera heptaphylla. 2) The food plant vegetation groups in Hainan gibbon habitat are divided into two vegetation types: tropical lowland rain forest, tropical mountain rain forest, including 8 and 6 formations respectively, with a total of 14 formations. The main dominant groups are: Form. Cryptocarya chinensis-Xanthophyllum hainanensisAlseodaphne hainanensis, Form. Adinandra hainanensis-Schefflera heptaphylla-Eurya nitida, Form. Schefflera heptaphylla-Canarium album-Bridelia balansae. 3) In terms of food plant vegetation groups in Hainan gibbon habitat, the richness of food plant vegetation types of the five family groups of Hainan gibbon is as follows: B family group(10 species) > A family group(9 species) > C family group(7 species) = D family group(7 species) = E family group(7 species). 【Conclusion】Hainan gibbons mainly inhabit tropical mountain rainforests and tropical lowland rainforests, and the vegetation composition is relatively rich. However, the composition of the types of food plants of different family groups is quite different, especially the difference of food plants between the A, B, C, D 4family groups and the E family groups is most obvious. The vegetation area of tropical mountain rainforest and tropical lowland rainforest in the habitat of 4 family groups A, B, C and D was roughly the same, and the vegetation types are relatively rich.However, all vegetation types of E family group belong to tropical lowland rainforest vegetation type, and the vegetation type is relatively single. This study can provide an important reference value for the vegetation restoration of the present and potential habitats of Hainan gibbon, which is conducive to improving the habitat quality of Hainan gibbon and promoting the recovery and development of Hainan gibbon species.更多还原
