利用20个野外调查的样地资料,分析了油松天然林主要种群种间联结及其生态位重叠特征,结果表明,秦岭中段油松天然林生态种对有8个:山杨-栓皮栎、秦岭木姜子-黄连木、光皮桦-青杄、色木槭-刺叶栎、色木槭-铁杉、盐肤木-槲栎、梾木-少脉椴、桦叶四蕊槭-青榨槭.在此基础上,利用聚类分析结果结合种群的生态位特征,将该区油松天然林划分为4个生态种组,其中油松独立成为了生态关键种的种组.结合生态种对,把第4个生态种组近一步划分为4个功能群:"广泛伴生种"、"嗜热物种"、"嗜湿物种"和"潜在建群种",各功能群都具有明显的生态过程(主要是物理过程和生物过程),能帮助解释物种对生态系统过程影响的机理.生态种对和生态种组两者结合分析植物功能群得出的结果合理,功能群之间的界定也比较清晰,符合各种群的生物学等的特征.
利用20箇野外調查的樣地資料,分析瞭油鬆天然林主要種群種間聯結及其生態位重疊特徵,結果錶明,秦嶺中段油鬆天然林生態種對有8箇:山楊-栓皮櫟、秦嶺木薑子-黃連木、光皮樺-青杄、色木槭-刺葉櫟、色木槭-鐵杉、鹽膚木-槲櫟、梾木-少脈椴、樺葉四蕊槭-青榨槭.在此基礎上,利用聚類分析結果結閤種群的生態位特徵,將該區油鬆天然林劃分為4箇生態種組,其中油鬆獨立成為瞭生態關鍵種的種組.結閤生態種對,把第4箇生態種組近一步劃分為4箇功能群:"廣汎伴生種"、"嗜熱物種"、"嗜濕物種"和"潛在建群種",各功能群都具有明顯的生態過程(主要是物理過程和生物過程),能幫助解釋物種對生態繫統過程影響的機理.生態種對和生態種組兩者結閤分析植物功能群得齣的結果閤理,功能群之間的界定也比較清晰,符閤各種群的生物學等的特徵.

The interspecific association of main populations of natural Pinus tabulaeformis forests in the middle part of Qinling Mountains and the characteristics of niche overlap were analysed base on field investigation. Results show that there are eight preliminary ecological twin species, namely Populus davidiana Dode-Quercus variabilis Blume, Litsea tsinlingensis Yang et P. H. Huang-Pistacia chinensis Bunge, Betula luminifera-Picea wilsonii Mast, Acer mono Maxim-Quercus spinosa David, Acer mono Meaim-Tsuga chinensis ( Franch. ) Pritz, Rhus chinensis WXL-Quercus aliena Blume, Swida macrophylla ( Wall. ) Sojak-Tilia amurensis, and Acer tetramerum Pax var. betulifolium ( Maxim. ) Rehd-Acer davidii Franch. Natural P. tabulaeformis forests in this area are classified into four ecological species groups according to the cluster analysis re-sults , in which Chinese pine become an independent species group of the ecological keystone species. The fourth ecological species group is divided into four plant functional types, all that have significant ecological processes and help to explain the affecting mechanism of the species to the ecosystem. The application of ecological twin species and ecological species group to the analysis of plant functional type could obtain a reasonable result and a clear definition of functional types, which accords with the biological characteristics of populations.
