To further explore the spatial structure pattern of natural Korean pine broad leaved forest and provide references for managing the natural forests,this study established a 1 hm~(2) plot in Dapo Region of Jiaohe Forestry Experimental Area,using TOPCON-GTS-602AF to survey every tree higher than 1.

Variation characteristics of soil N_2O emission flux in broad-leaved Korean pine forest of Changbai Mountain.;

Eco-value level assessment of broad-leaved Korean pine forest in Changbai Mountain;

Community type and species diversity of broadleaved-Korean pine mixed forest in Northeast China;

To study the dynamics of soil animals during the decomposition of Korea pine stump, a broadleaved-Korean pine mixed forest after selective cutting was selected, and soil samples were collected in a 14-year span, with different size soil animals identified and counted.

Microenvironmental heterogeneity of near surface layer illumination in the broad-leaved Pinus koraiensis forest gap;

Micro-environmental variation feature of soil surface temperature in a broad-leaved Pinus koraiensis forest gap;

Based on broad-leaved Pinus koraiensis forest gap in Xiao Xing an Mountains,microenvironmental heterogeneity of soil physical properties in 0-20 cm and 20-40 cm soil layers in the gap were analyzed by geographical statistics method.
