摘　　要：以赤峰市油松人工林为研究对象,设置251块人工林油松标准地以获取数据,对10种常用的导向曲线模型进行拟合,选择对数曲线式为最优导向曲线模型,相关指数达到了0.9957,离差平方和、相对误差等指标均较小。选定的导向曲线模型为H=-2.7021+0.0734A+2.3125×LgA,基准年龄为30年,级距为1m。采用标准差调整法编制了地位指数表。经卡方检验、散点检验和解析木检验证明,所编表合格、精度较高,可以用来评价油松人工林的立地质量。251 sample plots of Pinus tabuliformis plantation were set up in Chifeng City to obtain data.By fitting 10 common guiding curve models,the Logarithmic curve was chosen as the optimal guiding curve model with the correlation index of 0.995 7,and the small deviation square sum and relative error.The model H=-2.7021+0.0734×A+2.3125×LgA was selected as guide curve.The datum age was 30 years and the exponential distance was 1m.The standard deviation adjustment method was used to compile the site index table which was qualified and accurate and could be used to evaluate the site quality of Pinus tabulaeformis plantation by the chi-square test,scatter test and stem analysis.
