对重庆四面山常绿阔叶林建群种种子雨、种子库的研究表明,建群种早期和晚期的种子雨无活力;种子偏早或偏晚成熟及大籽粒的树种,其种子雨被取食的比例大;种子雨、有活力种子雨、种子库三者的数量变化不一致;有活力种子雨量较大的栲、石栎、小叶青冈、扁刺栲、香桂等,其种子库密度在早期以近几何级数的方式增长,元江栲、银木荷种子库小,存在时间短,翌年无一年生萌发苗;种子库数量动态、消减率动态决定于种子被取食的强度、种子衰老的速度以及种子对病菌、逆境的抗性和种子萌发的整齐性. The study on the seed rains and seed banks of evergreen broad-leaved forest in Chongqing shows that there is no seed rain in the early and late stages of the constructive species. The seed rain is more or less mature and the seeds of large seeds are eaten The seed germination rate was higher than that of the seed germplasm. The number of seed rains, viable seed rains and seed banks changed inconsistently. The seed germination rate of seedlings with vigorous rains, Quercus acutissima, Cyclobalanopsis glauca, In the recent geometrical progression, the seed banks of Yuanjiangfang and Yinmuhe were small with short existence time and no annual sprouting seedlings in the following year. The dynamics of seed bank dynamics were mainly determined by the intensity of seed feeding, the speed of seed senescence, Seed germs, adversity resistance and seed germination uniformity.
