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.
