不同经营方式下的蒙古栎次生林种间关系

摘要

Interspecific relationships of main populations of second forest for Quercus mongolica under different man-agement modes were studied .Species pairs which are of negative correlation under pure negative mode are :Pinus koraiensis- Lespedezabicolor ,Lespedezabicolor-Acer mono ;species pairs which are of positive correlation under pure negative mode are :Fraxinus mandschurica-Betula platyphylla ,Corylus mandshurica-Tilia mandshurica . there is no species pairs showing negative correlation in mixed forest ;there are positive correlations between Lespe-dezabicolor and Rosa xanthina .%通过对不同经营方式下的蒙古栎次生林主要建群种的种间关系进行的比较研究。结果表明：纯林模式下呈显著负相关的种对有红松-胡枝子、红松-五角槭，显著正相关的有水曲柳-白桦、毛榛子-糠椴；混交模式下没有呈显著负相关的种对，显著正相关的有胡枝子-黄刺玫。
