摘要
选用8个导向曲线模型对标准地内马尾松平均优势木的树干解析资料进行拟合。经筛选,确定Cubic函数作为最佳导向曲线模型,用标准差调整法编制了马尾松地位指数表,并对其精度进行了检验,经相关分析表明,该地位指数表精度高,实用性强。
Selected from eight models with data of stem analysis in the text, the best guiding curves is the cubic. The index table with the adjustable way of standard discrepancy is formed. After test on its precision, the result is that the site index table hold high precision and practicability .
