摘　　要：通过野外实地调查,结合标本和文献查阅,对深圳地区野生兰科植物种质资源、区系特征等进行研究。结果表明:(1)深圳野生兰科植物资源共43属75种,以深圳东南部的梧桐山和东部的七娘山较为丰富。其中地生兰28属49种,附生兰13属24种,腐生兰2属2种。(2)本次调查共发现9个深圳新记录种,其中叉柱兰Cheirostylis clibborndyeri、黄花线柱兰Zeuxine flava为广东省新记录种,二尾兰属Vrydagzynea、地宝兰属Geodorum为深圳新记录属。(3)深圳野生兰科植物区系以热带成分为主,占非世界属总数的87.5%,温带成分仅占12.5%。(4)与邻近地区比较,与香港共同属最丰富,有41属,占深圳总属数的95.3%;共有种70种,占深圳总种数的93.3%,具有明显的相似性。Based on field survey, specimens and literatures, Orchid resources and floristic characteristics in Shenzhen were studied. The results were showed as follows：（1） There were 75 orchid species, belonging to 43 genera, in which terrestrial orchids were dominant with 49 species in 28 genera, and 23 species in 13 genera for epiphytic and 2 species in 2 genera for saprophytic. Orchiaceous species were mainly distributed in Mt. Wutongshan and Mt. Qiniangshan.（2） Nine species were the new records to Shenzhen, in which 2 species of Cheirostylis clibborndyeri and Zeuxine flava were the new records to Guangdong province. 2 genera of Vrydagzynea and Geodorum were the new records to Shenzhen.（3） The geographical element of wild Orchidaceous flora in Shenzhen was predominated by tropical one, accounting for 87.5% of non-world genera, the temperate elements were occupied only 12.5% of non-world genera.（4） Comparing with neighboring regions, Orcidaceous flora of Shenzhen was similar to Hong Kong, between which there were shared 41 genera including 70 species, taking up 95.3% of total genera and 93.3% of total species in Shenzhen.
