摘要: 应用二元指示种分析(TWINSPAN)和无偏对应分析(DCA)对河南宝天曼植物群落进行了研究。结果表明:TWINSPAN将植物群落分成了岩栎林、千金榆林、铁木刺楸林、栓皮栎化香林、栓皮栎林、栓皮栎茅栗林、茅栗林、锐齿槲栎化香林、短柄锐齿槲栎林、山杨白桦林、锐齿栎林、化香漆树青榨槭林、青冈栎林、杜鹃林、杈叶槭水曲柳林、山茱萸林、栾树林、河楸枫杨林、飞蛾槭林、青檀林、黄荆灌丛、金钱槭银鹊树林和领春木林等2 3种类型;DCA排序结果基本上反映了植物群落与环境因子的关系,第1排序轴主要反映了热量的变化,第2排序轴主要反映了水分的变化。

Abstract: Plant communities in Baotianman,Henan Province were studied by the methods of Two-Way INdicators SPecies ANalysis (TWINSPAN) and Detrended Correspondence Analysis (DCA) in this paper.The results are as follows:Plant communitites were classified into 23 formations by TWINSPAN,they are Form.Quercus acrodenta, Form.Carpinus cordata,Form.Ostrya japonica+Kalopanax septemlobus,Form. Q.variabilis+Platycarya strobilacea,Form.Q.variabilis,Form.Q.variabilis+Castanea seguinii,Form.C.seguinii,Form.Q.aliena var.acuteserrata+P.strobilacea,Form.Q.glandulifera var.brevipetiolata+Q.aliena var. acuteserrata,Form.Populus davidiand + Betula platyphylla From.Q.aliena var.acuteserrata,From.P.strobilacea+Toxicodendron verniciflnum+Acer davidii,Form.Q.glauca,Form.Rhododendron purdomii,Form.A.robustum+Fraxinus mandshurica,Form.Macrocarpium officinalis,Form.Koelreuteria paniculata,Form.Catalpa ovata+Pterocarya stenoptera,Form.A.oblongum,Form.Pteroceltis tatarinowii,Form.Vitex negundo,Form.Dipteronia sinensis+Tapiscia sinensis and Form.Euptelea pleiospermum. Results of ordination by DCA reflect basically the relationship between plant communities and environmental factors,axis 1 and axis 2 reflect mainly the thermal and moisture gradients respectively.
