摘  要：
应用Ripley’sk(t)函数对长白山红松阔叶林空间格局进行分析.结果表明:蒙古栎、色木槭在所有研究尺度上分别呈完全随机分布和聚集分布;红松、水曲柳分别在0~13m及4~12m尺度范围上出现聚集分布;紫椴则在0~41m尺度范围上呈现聚集格局.紫椴、色木槭随着种群发育,聚集尺度范围及聚集规模逐渐减小.紫椴不同生长阶段间在小尺度上呈现空间正相关(最大尺度不超过3m);色木槭幼树与中树在11~12m尺度范围呈现空间正相关,而幼树与大树在4~6m尺度范围出现空间负相关.红松与紫椴(3~8m、38~50m)、色木槭(3~18m、46~50m)在小尺度以及较大尺度上呈空间正相关,与蒙古栎在大尺度(48~50m)上呈空间正相关;蒙古栎与水曲柳(2~3m、10~14m)、色木槭(3~4m)在小尺度上呈空间正相关;色木槭与紫椴则在中等尺度上(11~36m)呈空间正相关.

摘  要：
Ripley's K-function was used to characterize the spatial pattern of Korean pine broadleaved forests in Changbaishan Mountains, and this paper analyzed the structure characteristics of forest canopy gaps and the spatial correlation between forest canopy gaps and distribution pattern of tree species. The results showed that Quercus mongolica was distributed randomly at all spatial scales, Acer mono was significantly aggregated at all spatial scales, Pinus koraiensis and Fraxinus mandshurica were significantly clumped at the scales of 0-13 m and 4-12 m, respectively,and were randomly distributed at all other scales, whereas Tilia amurensis exhibited a clumped distribution at scales up to 41 m. Aggregation scale and scope of distribution pattern of T. amurensis and A. mono declined gradually, whereas aggregation intensity appeared the peak value at middle tree stage with population growing. T. amurensis indicated positive association at small scales among different growth stages (the largest scale is less than 3 m);Saplings were positively associated with middle trees at the scale of 11-12 m, and negatively associated with adult trees at the scale of 4-6 m for A. mono. P. koraiensis was positively associated with T. amurensis at the scales of 3-8 m and 38-50 m, with A. mono at the scales of 3-18 m and 46-50 m, with Q. mongolica at the scales of 48-50 m; Q. mongolica was positively associated with F. mandshurica at the scales of 2-3 m and 10-14 m, A. mono at the scale of 3-4 m; A. mono was positively associated with T. amurensis at the scale of 11-36 m.
