This paper deals w ith locals and vertical distribution of common plant species in four main tropical montane rain forestes in Hainan Island. T he results showed that although each forest area contained certain same dominant or funda mental species on species composition in those forests distribution in the east, middle and w est of Hainan, distinct ive dif ferences of species composition also ex isted in the ever forest regions. The ecological factor differences in each forest area lead to distribution differences in vertical distribution of species with different ecological amplitude. Since tempera ture, humidit , w ind, topograph , and soil varied with the different altitude, the distribution of various ecological ampli tude species diverged in the ecological factor effect. The species with narrower ecological amplitude distributed onl in limited area. For ex ample, the temperaturesensitive species of tropical floristic composition located just in mountain val le because of t he ecological influence. Some pure subtropical species onl distributed in tropical hill or subalpine area. However, the species with wider ecological amplitude or adaptation located from low to high altitude and from valle to mounta
