摘要

对海南大学儋州校区的苏木科(Caesalpinioideae)植物进行了调查研究.结果表明,校园内的苏木科植物共有7属15种,其中决明属(Cassia)植物7种,羊蹄甲属(Bauhinia)3种,凤凰木属(Delonix)1种,盾柱木属(Peltophorum)1种,云实属(Caesalpinia)1种,酸豆属(Tamarindus)1种,格木属(Erythrophleum)1种.由于在这些植物中,金凤花[Caesalpinia pulcherrima(L.)Sw.]、红花羊蹄甲(Bauhinia blakeana Dunn)和凤凰木[Delonix regia (Boj.) Raf.]的数量最多,分别为438丛、228棵和123棵,对这3种植物的具体分布和长势进行了更加详细的记录,分析其在校园内的园林应用状况,并为这3种植物在海南大学儋州校区园林绿化中的应用提出了参考意见.%In this paper,the plants of Caesalpinioideae in Danzhou campus of Hainan University were investigated.The results demonstrated that there are 7 genera and 15 species of Caesalpinioideae in the campus including 7 species of Cassia,3 species of Bauhinia,1 species of Delonix,1 species of Peltophorum,1 species of Caesalpinia,1 species of Tamarindus as well as 1 species of Erythrophleum.Among these plants,the number of Caesalpinia pulcherrima(L.)
