关帝山林区油松天然林生长规律的研究

研究关帝山林区不同立地条件油松天然林的生长过程，探讨其生长规律。进而为大面积营林，提高油松林生产力提供有力的理论依据。通过在关帝山林区采用建立标准地，选取优势木，进行树干解析的方法，对不同立地条件下油松天然林的树高、胸径和材积的生长规律进行了分析研究。结果表明，不同的立地条件对林木生长有显著影响。

Research on the Growing Regularity of Natural Forests of Pinus Tabulaeformis Carr. in Guandi Mountain

In order to study the growth of natural forests of Pinus tabulaeformis Carr. in different site conditions in the forest zone of Guandi Mountains, and to probe into their growing regularity, and further to provide strong theoretical proof for managing forests in large area and improving the productivity of the forests of Pinus tabulaeformis Carr., and through choosing dominant trees by setting up sample-plots in the forest zone of Guandi Mountain to make stem analysis, this paper analyzes on and probes into the growing regularity of the height, breast diameter and volume of the Pinus tabulaeformis Carr. in different site conditions, the result indicates that the different site conditions have obvious influences on the growth of natural forests of Pinus tabulaeformis Carr.
