中国亚热带常绿阔叶林优势种及常见种分布与气候的相关分析

RELATIONSHIP BETWEEN CLIMATE AND DISTRIBUTION OF MAIN SPECIES OF SUBTROPICAL EVERGREEN BROADLEAVED FOREST IN CHINA

广泛收集植物的分布资料，包括杨梅科、胡桃科、壳斗科、木兰科、樟科、山茶科、金缕梅科、交让木科、杜英科、五加科、安息香科、冬青科、杜鹃花科、山矾科的优势种和常见种１１２个，利用目前在国际上被认为是较好的几种研究植被－气候相互关系的指标和方法，包括：Ｋｉｒａ方法；Ｐｅｎｍａｎ公式；Ｔｈｏｒｎｔｈｗａｉｔｅ方法与分类；Ｈｏｌｄｒｉｄｇｅ生命地带分类系统指标与方法，分析中国亚热带常绿阔叶林优势种及常见种分布与气候的生态关系，找出它们的地理分布特征和气候指标特征，建立现代植被与气候的关系。（１）利用Ｋｉｒａ的温暖指数（ＷⅠ）和寒冷指数（ＣⅠ）及徐文铎的湿润指数（ＨⅠ），计算了中国亚热带常绿阔叶林１１２个优势种及常见种的水热指标值，分析了树种分布与气候的关系，并将优势种及常见种划分为５个Ｋｉｒａ水热指标分布类群。（２）计算了１１２个优势种及常见种的Ｐｅｎｍａｎ可能蒸散（ＰＥＴ）和干燥度（Ａ）值，划分了５个优势种及常见种的Ｐｅｎｍａｎ水热指标分布类群。（３）计算了树种的Ｔｈｏｒｎｔｈｗａｉｔｅ潜在可能蒸散（ＡＰＥ）及湿润指数（ⅠＨ）、干旱指数（ⅠＡ）和水分指数（ⅠＭ），划分了优势种及常见种的Ｔｈｏｒｎｔｈｗａｉｔｅ水热指?

A vast amount of material and literature of the horizontal and vertical distribution of dominants,main companions of subtropical evergreen broadleaved forest in China waere collected.112 dominants and main companions,including 14 families,were selected to study the relationships between the climate and the vegetation.Those families were Myricaceae,Juglandaceae,Fagaceae,Magnoliaceae,Lauraceae,Theaceae,Hamamelidaceae,Daphniphyllaceae,Elaeocarpaceae,Araliaceae,Styracaceae,Aquifoliaceae,Fricaceae and Symplocaceae,respectively.Kira's warmth index(WⅠ),Coldness index(CⅠ)and Xu's humidity index (HⅠ)of those 112 kinds of dominants and main companions were calculated.The groups of Kira's watertemperature distribution of main species of subtropical evergreen broadleaved forest in China were classified into five types.Penman's potential evapotranspiration (PET) and aridity (A) of the dominants and main companions were calculated.The groups of Penman's watertemperature distribution of main species of subtropical evergreen broadleaved forest in China were classified into five types.too.Thornthwaite's potential evapotranspiration(APE),humidity index(ⅠH),aridity index (ⅠA)and moisture index(ⅠM)of those 112 kinds of dominants and main companions of subtropical evergreen broadleaved forest in China were calculated.The groups of Thornthwaite's watertemperature distribution of the dominants and main companions were classified into five types.Holdridge's biotemperature (BT),potential evapotranspitation(PE),precipitation(P)and potential evapotranspiration ratio(PER)of the dominants and main companions were calculated.Holdridge's watertemperature distributional groups of main species of evergreen broadleaved forest in China were classified into five types too.
