【摘要】The spatial distribution and population dynamics of Quercus liaotungensis, Fraxinus rhynchophylla and Acer mono were studied in three warm temperate deciduous forests in Dongling Mountain. Clumped distributions appeared in most seedlings (≤0.4 m), short saplings (0.4-1 m) and tall saplings (1-2 m). Random distributions appeared in adults of Quercus liaotungensis in plot 1, Fraxinus rhynchophylla in plot 3. The LSD method was used to discern the differences of different aged population. The class distribution of Quercus liaotungensis, was nearly a reverse_J shape for plot 1 and plot 3, suggesting that the population regenerates continuously. The age_structures of Fraxinus rhynchophylla and Acer mono in plot 1 and the test results indicated that they would increase continuously. In plot 2, the class distribution and the test results showed that all populations would not regenerate continuously.%对北京东灵山地区三块样地中的辽东栎(Quercus liaotungensis)、大叶白蜡(Fraxinus rhynchophylla)和五角枫(Acer mono)种群的分布格局和种群动态进行了考察.调查三块样地中每个树种的全部个体,按高度将它们分为4个不同龄级,用相邻格子样方法进行取样.在研
