研究了太阳坪米心水青冈林中林窗的特征和更新行为。在５０００ｍ２的研究样地中，观察到林窗１０个，林窗面积占研究面积的４０．１％，平均大小２０１ｍ２。探讨了林窗的形成原因，米心水青冈的更新成分与林窗的大小呈正相关性。米心水青冈的更新是在由一个或几个林冠层树种死亡后形成的林窗中进行的。 The characteristics and rejuvenation behavior of Gap in the forest of Cyclobalanopsis glauca in solar pond were studied. In the 5000m2 study plots, 10 canopy gaps were observed, accounting for 40.1% of the study area, with an average size of 201m2. The formation reason of Gap was discussed, and the updated composition of Fritillaria nigra was positively correlated with the size of Gap. The renewal of the Pleurotus citri reticulum is carried out in a glenoid formed after the death of one or more canopy tree species.
