| 摘要: |
| 通过对深圳市宝安区2007年生态风景林改造前的马占相思林分进行样地调查，运用丰富度、多样性、均匀度等指标，研究了马占相思林下植物的多样性，结果表明：（1）林下物种主要是茜草科、禾本科、大戟科、菊科植物，样方中出现最多的物种为芒、春花、桃金娘、芒萁、酸果藤、鸡眼藤、梅叶冬青、山芝麻；（2）现有林下植物种类少，生物多样差异较大，不利于稳定群落的形成，建议在生态风景林改造时对部分地段进行林下植物的改造。 |

| Abstract: |
| Based on plot investigation data of Acacia mangium forest in Bao-an district, Shenzhen city, the undergrowth diversity of Acacia mangium is analyzed with richness, diversity and uniformity index. It indicates that:(1) most undergrowth belongs to Rubiaceae, Gramineae, Euphorbiaceae and Compositae. And the most common species are Miscanthus sinensis Andr., Rhaphiolepis indica Lindl, Rhodomyyrtus tomentosa(Art.)Hassk, Dicranopteris linearis (Burm. f.) Under, Embelia laeta (L.) Mez, Morinda parvifolia Bartl. et DC.，Ilex asprella(HK.et Arn.)champ.ex and Helicteres angustifolia L. (2) the number of undergrowth species is a little small in some extent, and species diversity varies greatly, which makes against the stability of community. Therefore, it is suggested that undergrowth should to be rebuilt in some plots with the rebuilding of ecological scene forest. |
