摘要
本研究基于黑龙江省五营林业局红松天然林标准地调查数据,研究红松天然林内种内和种间竞争关系。研究结果表明,红松的种内和种间竞争强度分别占总竞争强度的17.0%和83.0%,说明红松天然林种内竞争小,主要竞争来自种间。
Based on the data of Korean pine surveyed in Wuying Forest Bureau,intraspecific and interspecific competition relationship of Korean pine forest were studied.Results showed that： intraspecific and interspecific competition intensity of Korean pine were 17.0%,83.0% of total competition intensity,respectively.Hence,competition pressure of Korean pine mainly came from interspecies rather than intraspecies.
