Abstract: [Objective] In this paper, taking the coniferous and broadleaved mixed forest at different
development stages in Jiaohe, Jilin Province of northeastern China as research object, the interannual
variation of kernel density estimation curve of seedling density was compared and analyzed. The relative
effects of marginal changes of soil factors and distribution changes of soil factors on the dynamics of
seedling density distribution were discussed. [Method] Seedling investigation sample plots were
systematically arranged in 420 m × 520 m half-matured forest (HF) sample plots and 500 m × 840 m mature
