| Abstract: | According to some climatological indexes, such as annual average temperature and precipitation,Kira’s warmth and coldness indexes,Penman’s potential evapotranspiration and aridity, Thornthwaite’s potential evapotranspiration and moisture index,Holdridge’s biotemperature and potential evapotranspiration ratio, the relationship between climate and dominants and companions of subtropical evergreen broadleaved forest in China were analysed. The results of TWINSPAN classification and DCA ordination of dominants and main companions show that these species could be divided into 8 kinds of types. These water-temperature distributional groups are :1) Megathermal humid type:Engelhardtia fenzelii , Castanopsis lamontii , Castanopsis fordii , Castanopsis fabri , Castanopsis fissa , Castanopsis kawakamii , Cyclobalanopsis chungii , Michelia maudiae , Manglietia chingii , Litsea rotundifolia var. oblongifolia , Cryptocarya chinensis , Cryptocarya densiflora , Cryptocarya concinna, Phoebe bournei , Gordonia axillaris , Adinandra millettii , Altingia chinensis , Altingia gracilipes, Exbucklandia tonkinensis , Schefflera octophylla , Ilex ficoides.2) Mega-mesothermal humid type :Myrica rubra , Engelhardtia roxburghiana , Engelhardtia colebrookiana , Castanopsis carlesii , Castanopsis jucunda , Castanopsis hystrix , Lithocarpus glaber , Lithocarpus hancei , Lithocarpus harlandii , Cyclobalanopsis nubium , Cyclobalanopsis jenseniana , Michelia foveolata , Manglietia fordiana, Manglietia insignis. Litsea elongata, Neolitsea aurata, Cinnamomum burmannii, Machilus thunbergii , Gordonia acuminata , Ternstroemia gymnanthera , Cleyera japonica, Schima superba, Distylium myricoides , Daphniphyllum oldhamii , Daphniphyllum macropodum , Elaeocarpus decipiens , Elaeoearpus japonicus , Sloanea sinensis , Dendropanax dentiger , Styrax suberifolius , Ilex purpurea , Ilex latifolia , Vaccinium bracteatum , Symplocos anomala , Symplocos sumuntia. 3) Micro-mesothermal humid type:Fagus lucida Castanopsis eyeri , Castanopsis fargesii , Castanopsis sclerophylla , Castanopsis tibetana , Cyclobalanopsis multinervis , Cyclobalanopsis gracilis , Cyclobalanopsis gilva , Litsea coreana var. sinensis , Litsea coreana var. lanuginosa , Neolitsea aurata var. chekiangensis , Cinnamomum chekiangensis , Machilus leptophylla , Phoebe sheareri , Liquidambar acalycina , Styrax odoratissima, Ilex suaveolens, Ilex wilsonii, Rhododendron latoucheae, Rhododendron ovatum, Rhododendron fortunei , Symplocos stellaris.4) Mega-microthermal moist subhumid type Fagus longipetiolata , Lithocarpus polystachyus , Cyclobalanopsis myrsinaefolia , Cinnamomum camphora ,Sassafras tsumu.5) Micro-microthermal subhumid type Platycarya strobilacea , Cyclobalanopsis glauca , Neolitsea confertifolia , Lindera megaphylla, Lindera communis , Cinnamomum subavenium, Liquidambar formosana, Rhododendron mariesii. 6) Microthermal subhumid type Myrica esculenta, Fagus engleriana, Castanopsis carlesii var. spinulosa, Lithocarpus cleistocarpus, Quercus phillyraeoides , Quercus engleriana , Cyclobalanopsis oxyodon , Phoebe zhennan, Schima argentea.7) Mega-microthermal dry subhumid typeCastanopsis orthacantha, Castanopsis delavayi , Castanopsis ceratacantha , Lithocarpus dealbatus , Cyclobalanopsis glaucoides , Cyclobalanopsis delavayi, Cinnamomum glanduliferum, Machilus ichangensis ,Phoebe chinensis.8) Micro-microthermal dry subhumid type Castanopsis platyacantha , Quercus spinosa , Quercus spathulata. |
