以种子为繁殖体的植物更新模型研究

摘要/Abstract

摘要： 种子植物的自然更新过程是 20世纪 70年代以来生态学领域研究的热点问题之一。对影响种子植物更新过程因子的研究主要涉及 3个阶段,即种子生产、种子运动(主要为种子扩散的过程)和种子萌发、幼苗建成以及幼树生长到成树。一些完整的理论和实验模型被提出,反过来模型的研究促进了野外研究的进一步发展。关于种子植物更新的定性模型和定量模型陆续被提出,定量研究种子植物的更新过程将成为主要的发展方向。本文综述了近年来关于种子植物更新过程的 3个较为完整的定性模型,即Chambers等的种子命运模型、Clark等的补充限制模型和Nathan等的时空模型,以及 2个定量模型,即Vander和B hning等的种子扩散模型。

Abstract: Studies on plant regeneration have been one of the problems in the ecological field since 1970's. Lots of studies on factors influencing the regeneration of seed plants have been carried out, and mainly involved 3 stages, i.e., seed production, seed movement(mainly seed dispersal), and seed germination,seedling establishment and sapling maturity. Some detailed theoretical and experimental models were put forward, and promote field researches further. Many qualitative models and quantitative models have been proposed, and there was a tendency of carrying quantitative studies on regeneration of seed plants. The paper reviewed 3 qualitative models, i.e., Chambers et al . model of seed fates,Clark et al .'s models of recruitment limitation and Nathan & Muller Landan's spatio temporal model; and 2 quantitative models, i.e., Vander dispersal model of Purshia tridentata seeds and Bhning et al .'s dispersal model of Commiphora guiliamini seeds, which appeared in recent years.
