The study shows that the early and late seed rains of constructive tree species in evergreen broadleaved forest at chongqing simian mountain had no activity . the bigger the seeds of the species and the earlier or later the seeds of the species matured , the higher the proportion of the seed rain damaged by animals . the quantitative variation of seed rain , active seed rain and seed bank did not take place at the same time . at early time , the number of seed banks of castanopsis fargesii , lithocarpus glabra , quercus myrsinrefolia , castanopsis plasyacantha , cinamomum subavenium . which own more active seed rain increased by geomitric series . the seed banks of castanopsis orthacantha and schima argentea were small , only survived a short time , and did not sprout next year . the quantitative dynamics of seed banks and their increasing or decreasing rates were decided by the proportion damaged by animals , dying speed of seeds and their resistance to pathogens and adverse circumstances , and the state of seed germination 對重慶四面山常綠闊葉林建群種種子雨、種子庫的研究表明,建群種早期和晚期的種子雨無活力;種子偏早或偏晚成熟及大籽粒的樹種,其種子雨被取食的比例大;種子雨、有活力種子雨、種子庫三者的數量變化不一致;有活力種子雨量較大的栲、石櫟、小葉青岡、扁刺栲、香桂等,其種子庫密度在早期以近幾何級數的方式增長,元江栲、銀木荷種子庫小,存在時間短,翌年無一年生萌發苗;種子庫數量動態、消減率動態決定于種子被取食的強度、種子衰老的速度以及種子對病菌、逆境的抗性和種子萌發的整齊性

In the contrast , soil seed banks of bare patches were extremely small , in different seasons , especially in may and june , even no any seed have been found , mainly due to lowest retaining capacity of surface soil to those abundant seed movement 雖然土壤表面的種子流量巨大,但次生光鹼斑對種子的截留能力很低,土壤種子庫得不到及時更新與補充,常處于較低水平,尤其在5月份和6月份,土壤中甚至沒有種子出現。
