中文摘要：
使用252块北京市低山地区油松人工林标准地资料,统计分析各标准地优势木平均树高与年龄的关系,以双曲线式拟合树高生长导向曲线,编制出适用于该地区的油松人工林立地指数表;经χ2检验、落点检验和树高生长量检验后证明所编表合格;使用该表对252块标准地进行立地质量评价,结果表明,63%的标准地立地质量处在中等水平;油松最适宜生长的立地条件为阴坡厚土。
英文摘要：
Data from 252 sample-plots in the low elevation region of Beijing were used in this research. A site index table of Pinus tabulaeformis plantation was constructed based on the model which made by the statistical relationship between dominant tree height in each plot and the corresponding tree＇s age. The table was demonstrated to be of high accuracy when tested with three methods： chi-square test, test of falling point and test of height growth increment. Site quality of the 252 plots was evaluated by using the table. The results showed that 63 % of the total plots were in the middle site quality level, and the shady slope with thick soil was the best site condition fitting for Pinus tabulaeformis plantation＇s growth.
