摘　　要：以相邻自然灌草丛为对照,对广西喀斯特石山17年生翅荚木人工林林下植物多样性进行了调查分析,结果表明:翅荚木人工林林下共出现13科22属22种植物,其中灌木层有7科10属10种,草本层有6科12属12种,植物丰富度、Shannon-Wiener多样性指数、Simpson多样性指数均高于自然灌草丛。研究结果为科学评价翅荚木在喀斯特石漠化治理中的生态作用提供依据。In order to explore the plant diversity under Zenia insignis forests in Karst Rocky.Results shows that there are 22 species in 22 genera and 13 families in the understory of Zenia insignis,including 10 species in 10 genera of seven families in shrub layer,12 species in 12 genera in six families in herb layer.Plant richness,Shannon-Wiener diversity index and Simpson diversity index are higher than those of natural shrub.Result provides a basis for scientific evaluation of the ecological role of Zenia insignis in karst rocky desertification control.
