Wild resource diversity and conservation strategies of orchidaceous plants in Fujian Province.

摘要

In order to develop and utilize wild orchids, the situation of wild orchid resources in Fujian Province, one of the provenances of orchids, should be studied. By reviewing the related literature and analyzing the results from years of field surveys, 161 species or varieties in 71 genera of orchids (Orchidaceae) have been found in Fujian Province. They belong to three life forms, namely terrestrial type (40), epiphytic type (27), and saprophytic type (6). Besides, the vertical distribution of three life forms of wild orchids has also been studied, which shows that most of them are distributed from the altitude of 500 to 1000 m. The floristic elements of orchids studied can be divided into 10 types of geographical distribution, with the tropical type as the dominate type. Furthermore, 67 species of orchids, belonging to 33 genera, which are of high ornamental value, are divided into four types - flower type, foliage type, flower and foliage type, and view type. There are six genera and 12 species that are newly recorded in Fujian Province. Based on the research, targeted conservation and utilization strategies were given.
