摘要:

本研究通过对桂林岩溶石山232种主要木本植物的生长型、生活型、物候型、光习性、叶性质和果实类型进行统计分析，进一步揭示植物对生长环境的适应性，为今后桂林岩溶石山植被生态恢复、合理利用生态资源以及保持生态系统的可持续发展提供参考依据。结果显示：灌木有115种，乔木有89种，木质藤本有28种；大高位芽植物有3种，中高位芽植物有78种，小高位芽植物有98种，矮高位芽植物有53种；落叶植物有130种，常绿植物有102种；阳生植物有121种，阴生植物有111种；中型叶有126种，小型叶有105种，微型叶仅有1种；单叶有177种，复叶有55种；非全缘叶有127种，全缘叶有105种；革质叶有108种，纸质叶有98种，草质叶有25种，肉质叶仅有1种；单果有213种，聚花果有12种，聚合果有7种；单果中核果有63种，蒴果有47种，浆果有44种，荚果有17种，瘦果有13种，坚果有10种，翅果有8种，蓇葖果有8种，梨果有3种。表明桂林岩溶石山主要木本植物的功能性状是其生境条件和人为活动等因素的共同作用结果。

Abstract:

A statistical analysis of the functional traits (growth, life, phenology, light habits, leaf properties and fruit types) of 232 woody plants in karst hills of Guilin was conducted to further reveal the adaptability of plants to the growth environment, and provide reference for the future vegetation ecological restoration, rational utilization of ecological resources and sustainable development of ecological system in karst hills of Guilin. The results showed that there were 115 species of shrubs, 89 species of trees, and 28 species of woody vines. There were 3 species of large high bud plants, 78 species of medium high bud plants, 98 species of small high bud plants, and 53 types of short high bud plants. There were 130 kinds of deciduous plants, 102 kinds of evergreen plants, 121 kinds of heliophilous plants, and 111 kinds of sciophilous plants. There were 126 kinds of medium-sized leaves, 105 kinds of small leaves, and only 1 kind of mini leaves.There were 177 kinds of single leaves and 55 kinds of compound leaves. There were 127 kinds of non-whole leaves, and 105 kinds of whole leaves. There were 108 kinds of leathery leaves, 98 kinds of paper leaves, 25 kinds of grass leaves, and only 1 kind of fleshy leaves. There were 213 kinds of single fruits, 12 kinds of flower fruits, and 7 kinds of aggregate fruits. There were 63 kinds of stone fruits, 47 kinds of capsules, 44 kinds of berries, 17 kinds of pods, 13 kinds of achenes, and 10 kinds of nuts. There were 8 kinds of samara, 8 kinds of hazelnuts, and 3 kinds of pear fruit. The results show that the functional traits of the main woody plants in karst hills of Guilin are the result of the joint action of habitat conditions and human activities.
