Abstract: Liliaceous and Orchidaceous plants are important plant resources and have positive significance for studying the system evolution and species diversity.In this paper, plant resources of Liliaceae and Orchidaceae from Mt.Maluanshan in Shenzhen, China have been investigated and studied, the resutes showed that Liliaceous plants has 14 species of 9 genera, which account for 64.3% and 70.0% of Liliaceous total number in Shenzhen;and Orchidaceous plants has 28 species of 22 genera, which account for 68.8% and 54.9% of Orchidaceous total number in Shenzhen.Based on the study of Liliaceae, Orchidaceae plants of Fenghuangshan Forest Park (3 genera and 3 species of Liliaceae;4 genara and 4 species of Orchidaceae), Tiegang Forest Park (3 genera and 3 species of Liliaceae;4 genara and 4 species of Orchidaceae), Tanglangshan Country Park (5 genera and 5 species of Liliaceae;8 genara and 9 species of Orchidaceae), Wutongshan Scenic Area (8 genera and 12 species of Liliaceae;17 genera and 30 species of Orchidaceae), Paiyashan Nature Reserve (7 genera and 8 species of Liliaceae;26 genara and 35 species of Orchidaceae), Qiniangshan Country Park (9 genera and 10 species of Liliaceae;21 genara and 30 species of Orchidaceae), whitch are on the central axis of the Shenzhen region from west to east, combined with the ecological environment feature, indicating the indicative significance in ecological environment and forest vegetation.Hereby authors put forward some ways for strengthening protection, management and research.
