摘　　要：在中央站保护区,采用机械布点法设置收集器对种子雨和凋落物进行动态监测,并对主要树种的种子雨的组成、各月份之间的动态差异、时间动态、空间分布格局、凋落物的组成和时间动态进行分析.结果表明,种子雨主要由白桦、黑桦伴随少量兴安落叶松和蒙古栎种子组成;6月收集到的种子雨总量最多,其中种子雨量最多的树种是白桦;4个树种的种子雨的空间分布格局都呈现聚集分布;总凋落量和主要成分的凋落量呈明显的单峰型,其中凋落量以树叶为主,不同类别的凋落量都呈明显的单峰值.A collector is set up by the mechanical distribution method in the central station protection area to dynamically monitor the seed rain and litter.Analyzed the composition of seed rain of major tree species,the dynamic differences between months,time dynamics,spatial distribution pattern,composition and time dynamics of droplets.The results show that the seed rain is mainly composed of Betula platyphylla and Betula dahurica accompanied by a small amount of Larix gmelinii and Quercus mongolica seeds;the total amount of seed rain collected in June is the most,of which the tree species with the most seed rainfall is Betula platyphylla.The species of four tree species the spatial distribution pattern of sub-rain shows a cluster distribution.The total amount of withering and the amount of withering of the main components are obvious in the single peak type,in which the amount of falling is mainly leaves,and the amount of falling amount of different categories shows an obvious single peak.
