摘　　要：在野外考察的基础上,运用密度变化、相对径级离散度、自疏结局分析等方法对思茅松种群的自疏进行了研究。基于研究结果,认为思茅松纯林的管理应以天然更新为主、人工抚育间伐为辅。Based on the field survey for the self - thinning of Pinus kesiya var. langbianensis population, its density change, the relative DBH dispersion and self- thinning destiny were analyzed. The study indicates that the man- agement of the pure Pinus kesiya var. langbianensis forest should follow the natural regeneration, supplemented by the artificial thinning for caring.
