Characteristics of seed rain and falling objects in Heilongjiang Central Protection Area
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.
