Larix gmelinii Larix ginseng forest is the most important high-quality species in Daxinganling, according to 1985 statistics, Daxinanling Forest Management Larch accounted for 66.9% of the total volume of forest land, but compared with the initial establishment of the Bureau has been reduced by 24.4%, about 102227000 m ~ 3, at the same time, the proportion of broadleaf indeed increased. Therefore, to carry out the research on the growth process of natural larch is of great significance for cultivating high quality reserve resources in forest area.
