摘　　要：在厚朴人工纯林中选取一定数量对象木，以对象木为线索，研究厚朴人工林中的个体间的竞争与生长关系。选用简单竞争指数并建立与距离有关的单木生长模型。为预估厚朴林分的生长提供了一条简明有效的途径。ABSTRACT A number of target trees in plantations of officinalmagnolia，Magnolia offici-nalis，were selected to study the relationship between intraspecific competition and individualtree growth．The individual tree growth model relative to the distance between the trees wasderived by using the simple competitive stress index. The model has proved practical and ef-fective in predicting the stand growth.KEY WORDS Officinal magnolia；Simple competitive stress index；Individual tree growthmodel.
