For the purposes of making definite the category of species and the characteristics of communities of Odonata in Hainan Island, of enriching the information of biodiversity, and of a reasonable protection and utilization of Odonata resource in Hainan, the species richness, the fauna, the species-abundance and the diversity of Odonata communities in Hainan Island were studied based on surveys of the numbers of species and individuals. To make clear the relationship between environmental factors and the communities, a numeric classification and a ordination of the Odonata communities on 19 habitats were carried out by means of systematic cluster (SC) and principal componet analysis (PCA) respectively, using the species richness (S), the Shannon-Wiener diversity index (H’), the probability of interspecific encounter (PIE), the evenness (E) of the communities as attribute variables.There are 159 species and subspecies of Odonata in Hainan Island, belonging to 2 suborders, 4 superfamilies, 17 families and 94 genera. Among them, 5 genera including 5 species are of Megapodagrionidae, 2 genera including 4 species of Platystictidae, 7 genera including 16 species of Coenagrionidae, 3 genera including 5 species of Lestidae, 5 genera including 8 species of Calopterygidae, 3 genera including 3 species of Euphaeidae, 2 genera including 7 species of Chlorocyphidae, 1 genera including 2 species of Amphipterygidae, 3 genera including 7 species of Platycnemididae, 1 genera including 2 species of Protoneuridae, 23 genera including 30 species of Gomphidae, 1 genera including 1 species of Cordulegasteridae, 1 genera including 2 species of Chlorogomphidae, 8 genera including 13 species of Aeshnidae, 2 genera including 8 species of Macromidae, 2 genera including 3 species of Corduliidae, and 25 genera including 43 species of Libellulidae. Five genera (Anaciaeschna, Sinictinogomphus, Sieboldius, Macrogomphus, Zyxomma) and seven species (Anaciaeschna jaspidea Burmeister, Sinictinogomphus clavatus (Fabricius), Sieboldius alexanderi Chao, Macrogomphus guilinensis Chao, Zyxomma petiolatum Rambur, Cercion melanotum Selys, Anax parthenope julius Brauer) were first recorded in Hainan Island.The fauna analysis shows that oriental realm species and huanan realm species of Odonata are of dominance. There are 134 oriental realm species occupying 85.35% of species in Zoogeographic of the World, and 85 huanan realm species occupying 54.14% of species in Zoogeographic of China. The number of species in tropical mountain rain forest area is obviously greater than those in tropical monsoon broad-leaf forest area and in table-coase area. The categories of oriental realm species and endemic species are quite different among three areas, and so is the distribution of species.The species-abundance of Odonata communities in Baodao Xincun and that of in Hainan Island fit log-normal distribution model S(R)=17.7705exp-[0.1530(R-2)]~2 and S(R)=6.5302exp-[0.1119(R-3)]~2 respectively. The estimated numbers of Odonata species are 104 species in Baodao Xincun and 206 species in Hainan Island.According to the distribution of Odonata in different habitats, the species of Odonata in Hainan Island can be divided into three groups, the wide-adapted group, the mid-adapted group and the narrow-adapted group. The wide-adapted group consists of Pantala flavescens (Fabricius, 1798), Crocothemis servilia (Drury, 1770), Agriocnemis femina oryzae (Lieftinck, 1962), Pseudagrion rubriceps Selys, 1876, Copera marginipes (Rambur, 1842), Prodasineura autumnalis (Fraser, 1922), Ictinogomphus pertinax (Hagen, 1854), etc; the mid-adapted group consists of Urothemis s. signata (Rambur, 1842), Neurobasis c. chinensis (Linnaeus, 1758), Libellago lineata (Burmeister, 1939), etc; and the narrow-adapted group consists of Agriomorpha fusca May, 1933, Pseudolestes mirabilis Kirby, 1900, Coeliccia scutellum hainanense, etc.The studies of the community diversities, the numeric classification and the ordination of the Odonata communities on 19 habitats show that the species richness and the diversity indices descend in the following sequence: the mountain stream community, the plain stream-river community, the pond community, the paddy-garden community, the reservoir community and the artificial river community. This suggests that the structure of communities of Odonata be strongly affected by various factors, such as altitude, water body, flow speed, water quality, habitat size, substratum, vegetation richness and coverage, interruption from human, etc. Among them, water quality, vegetation richness, coverage and interruption from human were main key factors.Baodao Xincun was selected as the survey spot of monthly dynamics of Odonata communities. The results show that the occurrence of Odonata can be seen all the year round, and the numbers of species and individual are at the bottom in January and reach the peak in June, the second peak in October. The value of Shannon-Wiener diversity index (H’) is of minimum in January, and of maximum in June. However, the value of Evenness is quit stable all the year round.
