摘　　要：地位指数是立地质量相对于具体树种的数量化反映,也是森林经营和收获预估的重要依据.为了编制福建省火炬松多形地位指数,根据收集的火炬松人工林优势木树干解析资料,采用Sloboda树高生长数学模型,利用遗传算法拟合出火炬松优势高生长模型.精度检验表明:用Sloboda树高生长模型拟合的火炬松人工林多形地位指数曲线可以应用于林业生产实践.Site index is not only the quantity reflection of the of site quality of different species, but the im-portant basis of forestry management and harvest. In order to draw up the site index table of Pinus taeda plantation in Fujian province, according to the sample plot and stem analysis materials collected in Fujian Province, taking the genetic algorithm to simulate the height growth curve of dominant tree by B.Sloboda's height growth model. As a result, the height growth curve of Pinus taeda plantation is available for forestry production.
