中文摘要：

为了客观认识大别山五针松（Pinus dabeshanensis）与其所在群落中主要优势种的种间关系,采用样方法进行群落调查,然后用x 2检验、Ochiai关联指数、Pearson相关分析和Spearman秩相关分析法对天马自然保护区大别山五针松群落中大别山五针松与其它14个优势树种的种间联结和相关性进行了研究.结果表明：Spearman秩相关分析结果灵敏度较高,表明大别山五针松（Pinus dabeshanensis）与黄山松（Pinus taiwanensis）、短柄枹（Quercus glandulifera var.brevipetiopetiolata）、栓皮栎（Quers variabilis）、天目杜鹃（Rhododendronfortunei）呈极显著正相关,与茅栗（Castanea seguinii）、五角枫（Acer mono）呈显著正相关.与白檀（Symplocos paniculata）呈极显著负相关,与蜡瓣花（Corylopsis sinensis）、荚蒾（Viburnum dilatatum）呈显著负相关.据以上分析,可把大别山五针松、黄山松、短柄枹、栓皮栎、天目杜鹃、茅栗和五角枫划为一个生态种组.保护和管理大别山五针松时,控制群落中非同一生态种组的物种,如白檀、蜡瓣花、荚蒾等,从而促进大别山五针松尽快郁闭成林.

英文摘要：

Pinus dabeshanensis is an endangered plant species, and an endemic species of Mount Dabie. Its endangerment mechanism is complex and unclear. In order to objectively understand interspecific relationship between Pinus dabeshanensis and other dominant species, a study was performed to investigate the interspecific relationship between Pinus dabeshanensis and fourteen dominant species in the community at Tianma National Nature Reserve, Jinzhai County, Anhui Province. The community with Pinus dabeshanednsis was surveyed. Fifteen 20 × 20 m2 quadrats were set. Tree species, tree height, diameter at breast height, clear bole height, crown width, coverage, number were investigated and recorded. Z2-test, Ochiai association index, Person＇s correlation coefficient and Spearman＇s rank correlation coefficient were used to analyze the interspecific relationship. Results showed that it was higher sensitivity by Spearman＇s rank correlation coefficient test than any other tests. There was very significant positive interspecific relationship at 0.01 level between Pinus dabeshanensis and Pinus taiwanensis, Quercus glandulifera var. brevipetiolata, Quercus variabilis, Rhododendron fortunei, and it was significant positive interspecific relationship at 0.05 level between Pinus dabeshanensis and Castanea seguinii, Acer mono. There was very significant negative interspecific relationship at 0.01 level between Pinus dabeshanensis and Symplocos paniculata, and there was significant negative interspecific relationship at 0.05 level between Pinus dabeshanensis and Corylopsis sinensis, Viburnum dilatatum. According to these interspecific relationships between Pinus dabeshanensis and the other fourteen species, an ecological species group was established, including Pinus dabeshanensis , Pinus taiwanensis , Quercus glandulifera var. brevipetiolata , Castanea seguinii , Acer mono. When protecting and managing Pinus dabeshanensis, the plant species that showed the positive interspecific relationship can be symbiosis and reciprocal to so
