The comparison analysis on floristic components of Korean pine broad-leaved secondary forest in Liangshui Nature Reserve and Maoershan Nature Reserve illustrated the difference of floristic components and the influencing factor between two nature reserves.

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;

Species diversity and its seasonal dynamics or herbs in a broad-leaved korean pine forest on the northernslope of the Changbai Mountain;

Landscape diversity and stability of Korean pine broad-leaved forest in Xiaoxing anling forest region.;

Storage dynamics of fallen trees in Korean pine broad-leaved forest.;

Early-spring herbs are central synusia to the plant community in Korean pine broad-leaved forest.

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.

Nutrient uptake and return of early-spring herbs in broadleaved Korean pine forest in Changbai Mountains;

Analysis of the effects of disturbance on artificially inducing broadleaved Korean pine forests showed that tending the secondary forests for 32 years,by using twice upper storey cutting(selectively cut and remained the trees in the upper layers),parts of Korean pine grew into main storey and became the dominant populations.

This paper analyzes the life history process of Korean pine ( Pinus koraiensis ) populations and the influencing factors in natural broadleaved Korean pine forests in the Xiao xing an Mountains of northeast China.
