大兴安岭兴安落叶松林25公顷样地建于2011年,位于大兴安岭北部伊勒呼里山北坡,具有中国东北大兴安岭寒温带地带性典型植被,地理位置51.82°N122.98°E。样地地形平缓,平均海拔897 m,最大高差16.6 m,年均气温-4℃,年均降水量458.3 mm,年相对湿度平均为71%,年蒸发量平均911 mm

大兴安岭样地群落结构较简单,是以兴安落叶松(Larix gmelinii)为建群种的寒温带针叶林,兴安落叶松为主要优势种,并形成藓类—兴安落叶松林、草类—兴安落叶松林、杜香(Ledum palustre)—兴安落叶松林和兴安杜鹃(Rhododendron dauricum)—兴安落叶松林4种主要群落类型,体现出寒温带针叶林的植被景观特点。

样地内共有DBH1cm的木本植物18种,其中乔木4种,灌木14种,隶属于612属,独立个体数为209,785株。样地内最大胸径为52 cm,平均胸径3.87 cm,胸髙断面积20.93 m2/ha

The 25-ha dahurian larch forest plot is a typical cold temperate zonal vegetation of Daxinganling Region, which was established in 2011, located in the north slope of Yilehuli mountains, with the geographical coordinates 51.82°N122.98°E. The mean elevation is 897 m, with a gentle difference of altitude of 16.6 m. The mean annual temperature is -4, mean annual precipitation 458.3 mm, mean annual relative humidity 71%, and mean annual evaporation 911 mm.

The plot has a relatively simple community composition, Larix gmelinii is the dominant species. There are four main community types represented common vegetation landscape characteristics, including: moss - Larix gmelinii forest, herbage - Larix gmelinii forest, Ledum palustre - Larix gmelinii forest, and Rhododendron dauricum- Larix gmelinii forest.

Total number of individuals with DBH1 cm was 209,785 recorded in the plot, belonging to 18 woody species (4 tree species, 14 shrub species), belonging to 12 genera and 6 families. The maximum DBH in the plot was 52 cm, the mean DBH and basal area were 3.87 cm and 20.93 m2/ha, respectively.
