Variations of population structure and important value of the main edificators along the elevation gradient on the northern slope of Changbai Mountain

Abstract

From 700 m to 1900 m on the northern slope of Changbai Mountain, 13 plots with an interval of 100 m in elevation were investigated to study the variations of population structure and important value of the main edificators along the elevation gradient. In their core distribution areas, most of the edificators had healthy population structure and could regenerate smoothly exceptLarix olgensis, but important value ofLarix olgensis had no obvious variations with elevation changes, which showed thatLarix olgensis had its own particularity and strong adaptability. At high elevation above 1800 m,Betula ermanii was the only species that could form a mono-dominant community. Important values ofPinus koraiensis andAcer mono had similar changing trends, and they had the similar ecological adaptabilities.
