To explore the relationship between the functional properties and ecological adaptability of angiosperms in the special habitat of the Mengdong River Valley in Hunan, the method of combining line survey and sample survey was adopted to investigate and analyzed from life habits, leaf properties, sexual system, fruit type and seed transmission of angiosperms in the Mengdong River Valley. The results indicated that: (1) The Life habits in this area was mainly herbaceous, indicating that the valley habitat was more suitable for the development and survival of herbaceous. (2)The shape of leaf organs was dominated by papery leaves, leaf two sides glabrous and the middle leaf type, forming a series of features adapted to river valley habitats. (3) In terms of sexual system composition, the family was dominated by two or more sexual systems, and the genus and species were dominated by hermaphroditism, indicating that the plant propagation in the river valley habitat were diverse. (4)The fruit types were abundant, among which capsules, berries and achenes appear more frequently, and with dried fruit based, indicating that the river valley habitat was highly heterogeneous and was also suitable for the survival of dried fruit plants. (5) The main method of seed transmission was mechanical transmission, showing that the gradient of the river valley was steep hence it was suitable for the seeds to roll automatically for a long distance to spread.
