摘要：通过对深圳市宝安区已列入2007年生态风景林改造工程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,林下已出现众多的乡土植物种类,其物种构成主要包括桃金娘科、铁线蕨科、菊科、禾本科、蔷薇科、梧桐科、茜草科、樟科、冬青科的植物,样方中出现最多的物种为桃金娘、扇叶铁线蕨、假臭草、芒、春花、山芝麻、九节、鸡眼藤、豺皮樟、梅叶冬青等;但各样方的丰富度和物种多样性并不高,且分布不均匀,表明马占相思人工林对乡土物种多样性有一定的影响,但并不会造成根本的破坏。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,以提高物种多样性。
Based on plot investigation data of Acacia mangium plantation in Bao-an district, Shenzhen city, undergrowth species richness, diversity, and evenness index were analyzed. The results indicated that many native species occurred in the understory, and most undergrowth species belonged to Myrtaceae, Compositae, Gramineae, Rosaceae, Sterculiaceae, Rubiaceae, Lauraceae, and Aquifoliaceae, with the most common species being Rhodomyrtus tomentosa （ Ait. ） Hassk. , Adiantum flabellulatum L. , Eupatorium catarium Veldk. , Miscanthus sinensis Anderss. , Raphiolepis indica （L.）Lindl. , Helicteres angustifolia L. , Psychotria rubra （Lour.） Poir, Morinda parvifolia Bartl. ex DC. , Litsea rotundifolia Hemsl. var. oblongifolia （Nees） Allen, and Ilex asprella （HK et Am. ） Champ. ex Benth.. However, species richness and diversity in each plot were low and unevenly distributed, indicating that A. mangium may have an effect on the undergrowth diversity but this effect is not detrimental and exclusive. Therefore, it is suggested that the understory community structure of the A. mangium plantation should be rehabilitated in some locations with the rebuilding of ecological scenic forest.
