Abstract: The conservation of plant species diversities in the Three Gorges reservoir area was carried out by collection and conservation of dominant species of communities and species of practical value, with emphasis on rare and threatened plants. More than 200 species in the Three Gorges reservoir area have been planted in experiment stations since 1996, the survival percentage was 93%, while 8 species failed to success. By 2002, more than 30 species (including 24 wood plants) developed flowers and set fruits normally; 8 species were selected to record their growth process; Several species were cuttage reproduced and spore propagated; Collection of some species faced great difficulty. There are some problems and difficulties in the study and conservation of biodiversity in the Three Gorges reservoir area, for example, the missing items, the species list of Three Gorge district, the invasive species, effect of isolation on biodiversity, and function of biodiversity, etc., which need further concern and studies.

Key words: the Three Gorges reservoir area, exsitu conservation of land plants, biodiversity
