摘要: 为了揭示不同径阶油松Pinus tabulaeformis林群落内光辐射状况，以北京市妙峰山实验林场内人工油松林为研究对象，运用WinSCANOPY For Canopy Analysis冠层分析仪采集数据，并结合实地调查，实测了5种不同径阶的油松林群落内光辐射特征及冠层结构参数。结果表明：立地条件相同的情况下，油松林内光辐射随胸径增加呈下降趋势，为14.64 ～ 22.43 MJ·m－2·d－1，平均约占冠上总辐射的64.59%。林分开阔度为24.91% ～ 43.77%，并且不同径阶群落之间有明显差别。叶面积指数为2.23 ～ 4.50，平均约为3.67。冠层消光系数小于0.20，较小的消光系数对林内灌木层和草本层生长更新具有重要意义。图4表1参30

Abstract: Light is a dynamic factor that affects the course of community succession and plant survival strategies. To reveal the light environment and provide reference for improving plantation structure，five Pinus tabulaeformis communities of different diameter classes in Beijing’s Miao-feng Hill Forest Farm were studied. Photos were produced with WinSCANOPY，and light characteristic indexes，along with canopy structure parameters，such as photosynthetic photon flux density （PPFD），canopy openness，leaf area index （LAI），and the light extinction coefficient（k），were analyzed by using standard plots method. Results showed that in the same habitat，total PPFD under the canopy ranging from 14.64 to 22.43 MJ·m-2·d-1 or about 64.59% of the PPFD above the canopy，decreased with increasing diameter at breast height （DBH）. Canopy openness was between 24.91% and 43.77%，whereas LAI ranged from 2.23 to 4.50 with an average of 3.67. Also，light extinction coefficients of all five communities were less than 0.20. Therefore，the light environment under these P. tabulaeformis communities was sufficient for growth and regeneration，to some degree，of the shrub and herb layers. ［Ch，4 fig. 1 tab. 30 ref.］
