依托黑龙江凉水国家级自然保护区9 hm2典型阔叶红松林动态监测样地的900个2 m×2 m多年生幼苗(H≥30 cm,DBH<1 cm)样方,基于2006、2008和2010年3次调查数据,分析了地形对幼苗建立的影响.结果表明:样地内共有乔木幼苗26种,2006、2008和2010年的乔木幼苗总数分别为4514、6464和5611株·hm-2.其中个体数前10位树种的幼苗数量占幼苗总数的90%以上.地形对8个主要乔木幼苗的分布有显著的影响,其中暴马丁香、冷杉、色木槭、春榆、花楷槭、紫椴和青楷槭幼苗与其成树分布基本一致,而红松幼苗的空间分布与成树分布有所不同.暴马丁香、冷杉、裂叶榆、青楷槭和紫椴幼苗的死亡与地形显著相关.暴马丁香、春榆、红松、冷杉、水曲柳、色木槭和紫椴新增幼苗与地形显著相关.
Based on the quadrats of 900 2 m × 2 m perennial seedlings (H ≥ 30 cm, DBH <1 cm) sampled from 9 hm2 typical Korean pine broad-leaved forest in Heilongjiang National Nature Reserve, The data of three surveys analyzed the effect of topography on seedling establishment.The results showed that there were 26 species of tree seedlings in the plots, and the total number of tree seedlings in 2006, 2008 and 2010 were 4514, 6464 and 5611 plants per hectare, respectively The number of seedlings in the top ten species accounted for more than 90% of the total number of seedlings.The topography had a significant effect on the distribution of seedlings in eight main trees, among which the species of Cymbidium rugosa, Fir, Maple, Maple, Tilia amurensis And Qinghai maple seedlings and its distribution is basically the same, and the spatial distribution of the Korean pine seedlings and the distribution of trees are different .Bus rugosa, fir, Crassulaceae, maple and Tilia amurensis seedlings death and terrain was significantly related The newly - added seedlings of Cyclops, Chunyu, Korean pine, Fir, Ash, Acer palmatum and Tilia amurensis were significantly correlated with the topography.
