以北京市密云半城子侧柏水源涵养林为研究对象,提出了改进的邻体干扰模型,着重讨论了干扰指数与侧柏的胸径、树高、生境利用率等因子的关系。结果表明,侧柏林内的邻体干扰指数与林木的胸径、树高、生境利用率呈负相关关系。本研究为该地区水源涵养林的经营提供了具有参考价值的量化依据。
Taking the Oriental Arborvitae watermelon conservation forest in Miyun, Beijing as an example, an improved neighbor interference model was proposed, and the relationship between the disturbance index and the DBH, tree height and habitat utilization was discussed emphatically. The results showed that there was a negative correlation between the neighbor index and the DBH, tree height and habitat utilization of the forest. This study provides a quantitative basis for the management of water conservation forest in this area.
