Study on Understory Herbaceous Diversity of Broad-Leaved Mixed Forest in Eastern Foot of Greater Khingan Mountains
Chinese Greater Khingan Mountains region is rich in vegetation resources,and the typical forest broad-leaved mixed forest occupies an important position in the entire forest community.The study of its species diver-sity changes with altitude and slope is an important work.This paper selects 4 typical broad-leaved mixed forest communities in the Greater Khingan Mountains area according to different altitudes and slope directions as the re-search objects,set up plot and analyze the species diversity in the plots.The research results show that:①altitude has a significant impact on the understory herbaceous biodiversity,showing a significant positive correlation P＜0.01);②understory herb biodiversity will be affected by the aspect,and the understory herb biodiversity will in-crease significantly from sunny slope to shady slope(P＜0.05);③elevation and aspect will affect the understory herbaceous biodiversity by affecting the stand structure(P＜0.001).
