摘　　要：为了明确影响蒙古栎生长的主要环境因子,促进蒙古栎林分质量提升,以清原县蒙古栎天然次生林为研究对象,根据林龄、坡向、坡位等条件建立68块标准地,利用数量化方法研究蒙古栎生长与立地因子的关系。结果表明,辽东地区蒙古栎天然次生林以坡度为主导因子可划分为3个立地类型组,40个立地类型;以坡度15°以下的平缓坡、下坡位、阳坡以及土壤A层较厚的地段为最适宜蒙古栎生长的立地条件。研究结果为辽东山区天然蒙古栎次生林的合理经营提供理论依据和技术支撑。In order to identify the main environmental factors affecting the growth of Quercus mongolica and promote the quality improvement of Q. mongolica stand, the natural secondary forests of Q. mongolica in Qingyuan County,Fushun City,Liaoning Province were studied. 68 temporary standard plots of Q. mongolica with different ages, slope directions and slope positions were established. The relationships between the growth of Q. mongolica and site factors were studied by quantitative method. Results showed that the natural secondary Q. mongolica forest in eastern Liaoning was divided into 3 site-type groups and 40 site types by taking slope as the dominant factor. The most suitable site condition for Q. mongolica growth in eastern Liaoning was gentle slope below 15°, at lower position, sunny slop and with thick A layer soil. The results provide theoretical basis and technical support for reasonable management of natural secondary forest of Q. mongolica in Eastern Liaoning.
