摘要(Abstract)：

通过对马尾松(Pinus massoniana)-麻栎(Quercus acutissima)人工混交林的124株对象木及473株竞争木的调查,采用竞争影响区域法与HEGYI单木竞争模型相结合的方法对马尾松-麻栎人工混交林的种内、种间竞争关系进行研究。结果表明,样地内Ⅳ级和V级马尾松数量较多,所占的比重较大;I级马尾松幼苗数量较少。马尾松种内和种间竞争强度均随对象木径级的增大而减小,同一径级的种间竞争均大于种内竞争。竞争强度与对象木胸径的关系服从幂函数关系CI=AD~(-B),当对象木胸径DBH≥20cm时,竞争强度无明显变化。所得的预测模型能很好的预测马尾松-麻栎人工混交林种内和种间竞争强度。
