以山西灵空山自然保护区油松(Pinus tabulaeformis)-辽东栎(Quercus wutaishanica)林4hm2样地调查数据为基础,采用O-ring点格局分析方法,对油松-辽东栎林建群种的不同空间格局关联性进行分析,结果表明:油松种群不同空间的关联性表现为0～20m小尺度上的正关联,辽东栎种群不同空间的关联性基本表现为无关联;上层辽东栎与油松各层之间及上层油松与中层辽东栎的空间关联性在0～20m的水平空间尺度上表现为负关联,>20m的水平空间尺度上表现为无关联,中层辽东栎与下层油松的空间关联性在0～10m的水平空间尺度上表现出不显著的正关联,>10m的尺度上表现出无关联,中层辽东栎与中层油松、下层辽东栎与油松各层的空间关联性则表现出无关联;油松和辽东栎种内的垂直空间关联性均表现为正关联或无关联,而二者的种间关联性在0～20m的小尺度垂直分布格局上表现出负关联。
Based on the survey data of Pinus tabulaeformis-Quercus wutaishanica forest 4hm2 in Lingkangshan Nature Reserve in Shanxi, different spatial patterns of Pinus tabulaeformis-Quercus wutaishanica forest stand were studied by O-ring point pattern analysis. The results showed that the correlation of different spatial populations of Pinus tabulaeformis populations showed a positive correlation at the 0-20 m small scale, and the correlation of different spatial populations of Quercus liaotungensis was basically unlinked. The upper layers of Quercus liaotungensis and Pinus tabulaeformis And the spatial correlation of Pinus tabulaeformis and Quercus liaotungensis in the upper layer showed a negative correlation on the horizontal spatial scale of 0 ~ 20m. The horizontal spatial scale of> 20m showed no correlation, and the spatial correlation of Quercus liaotungensis and Pinus tabulaeformis in the middle layer There was no significant positive correlation between the sex and the spatial scale of 0 ~ 10m. The spatial correlation was found on> 10m scale. The spatial correlation between Quercus liaotungensis and Pinus tabulaeformis and the lower layers of Quercus liaotungensis and Pinus tabulaeformis There was a positive correlation or no correlation between the vertical spatial correlations within Pinus tabulaeformis and Quercus liaotungensis. The interspecific correlation between the two showed a negative correlation on the small-scale vertical distribution pattern of 0-20 m.
