摘要
本文应用关帝山庞泉沟自然保护区标准地复查资料，研究了华北落叶松林邻体间相互干扰的问题。在前人工作的基础上，提出了用冠幅代替胸径表示邻体竞争关系的干扰指数改进模型，此模型不但保证了其数学上逻辑的一致性，同时增加了生态学的解释意义，提高了模型的精确度。
This paper deals with the neibourhood interference of larix principis-rupprecchtii.by means of the materials of monumented samples in Pengquangou conservation area.Based on the previous works,we put forword the improved index model of neighbourhood interference.The logical,ecological meanings and the accuracy of the model have been increased with improvvement.
