摘要:

为探究热带珊瑚岛植物对高温、高光照、土壤贫瘠生境的适应性，对热带珊瑚岛不同生活型植物叶片功能性状及其生态适应策略差异进行研究。结果表明，不同生活型植物叶片全N、纤维素含量，C/N、水分利用效率和比叶面积存在显著差异；叶片功能性状间的显著相关性表明植物在资源分配和生长投资间存在权衡；不同物种在珊瑚岛生境中采取不同的生态策略，且呈现明显趋异性。在热带珊瑚岛植被恢复实践中，可优先选择的乔木树种为抗风桐(Pisonia grandis)，灌木为银毛树(Tournefortia argentea)，但同时要防范飞机草(Chromolaena odorata)、孪花蟛蜞菊(Wollastonia biflora)和南美蟛蜞菊(Sphagne- ticola trilobata)的扩张。

Abstract:

In order to understand the ecological adaptability of plant species to high temperature, intense radiation and deficit soil in tropical coral islands, the differences of leaf functional traits and the ecological strategies among different life forms of plants grown on coral island were studied. The results showed that there were significant differences in total N, cellulose concentrations, leaf C/N ratios, water use efficiency and specific leaf area among the life forms, and there were significant correlations among leaf function traits, indicating trade-offs between resource allocation and growth investment of the plants. Plant species exhibited significantly different and divergent ecological strategies grown in the coral islands. In the practice of vegetation restoration in coral island, plant species like Pisonia grandis and Tournefortia argentea could be preferentially adopted, but herb like Wollastonia biflora, Chromolaena odorata and Sphagneticola trilobat should be strictly monitored to avoid their expansion.
