鄂西狮子关常绿阔叶林优势种群生态位研究
The Study on Niche of Dominant Poputions of Evergreen Broadleaved Forest at Shiziguan in the Western Hubei
【摘要】 在对鄂西宣恩县狮子关森林群落样方调查的基础上 ,通过定量分析 ,研究了常绿阔叶林优势种群的生态位 .结果表明 :①优势种群的Levins和Shannon Wiener生态位宽度指数值大小顺序均为 :构栲 ,丝栗 ,马尾松 ,锥栗 ,山合欢 ,杉木 ,枫香 ,亮叶桦 ,虎皮楠 ,总状山矾 ,柏木 (白辛树 ) ;②柏木与杉木、锥栗与山合欢、丝栗栲与白辛种对之间重叠值最高 ,而同属植物构栲与丝栗栲生态位重叠值较低 ,仅为 0 10 8和 0 0 77.
【Abstract】 Based on large numbers of sampling unite of the forest communities at area of Shiziguan in the western Hubei province, the niche eidth and overlap of domianant populations of broadleaved forest were studide by quantiative method in this paper. The results show that: ①the order of Levins & Shannon-Wiener niche width index number are both C.② tibetana,C. fargesit,P. massoniana>C. henryi,A. kalkora,C. lanceolata,L. formosana,B. luminifera,D. oldhamii,S. botryantha,C. funebris(P. psilophylla). ②the values of niche overlap with species contrast of C. funebris & C. lanceolata, C. henryi & A. kalkora, C. fargesit & P. psilophylla are highest. And the value of niche overlap with species contrast of C. tibetana & C. fargesit is low.
