对长白山阔叶红松林的林隙环境状况、林隙内物种种间关系进行了研究。结果表明:林隙与林内物种丰富度不同,乔木物种丰富度略高于林内,而灌木和草本物种丰富度则明显高于林内;林隙内物种种间关系多数呈负相关,极显著正相关(P<0.01)和显著正相关(P<0.05)种对数较少(乔、灌、草),极显著负相关(P<0.01)和显著负相关(P<0.05)种对数也较少(乔)或没有(灌、草),物种间主要表现为竞争关系;林隙中小气候状况发生了显著改变,光照强度和空气温度显著高于林内(P<0.01),空气相对湿度和地温变化规律也表现出显著变化。
The situation of gap environment and the relationship among species in the gap were studied in broad-leaved Korean pine forest in Changbai Mountain. The results showed that species richness in gap and forest was different, species richness of tree was slightly higher than that in forest, while species richness of shrubs and herbs was significantly higher than that in forest. Most of the species in gap was negatively correlated with extremely significant positive correlation (P <0.01) and significant positive correlation (P <0.05). There was also a significant negative correlation (P <0.01) and a significant negative correlation (P <0.05) There was a significant change in the microclimate conditions in the gaps, and the light intensity and air temperature were significantly higher than those in the forest (P <0.01). The air relative humidity and ground temperature Changes in the law also showed significant changes.
