胡杨种群生殖生态学研究进展

Advance in the Research on Reproductive Ecology of Populus euphratica

生殖生态学的研究是解决我国西北荒漠绿洲重要树种胡杨退化问题的关键。论述了胡杨生殖生态学研究的概况;重点从有关胡杨种群的生活史对策、生殖物候学、生殖构件、种子和幼苗的生态学、繁殖适应、无性繁殖以及干扰对胡杨群落更新的影响等7个方面系统的评述了胡杨的生殖生态学研究的现状和存在的问题;并针对胡杨林的恢复与保护的角度,从其有性繁殖适应对策、根蘖繁殖发生机制以及优良种源地的选择与保护等方面进行展望。

Reproduction is a primary behavior and process for all organisms to multiply their descendants, and is also a research hotspot of conservation and restoration of populations in severe danger. The study on reproductive ecology is the key treme arid area in to solve the restoration and conservation of degraded populus euphratiea forest at oasis of the exnorthwest China. The history of reproductive ecology of populus euphratiea was briefly reviewed.Furthermore, the main aspects of study on reproductive ecology of populus euphratica was systematically discussed, which includes life history related to reproduction, reproductive phenology, reproductive modula, reproductive strategies, asexual reproduction and effects of disturbance to regeneration of populus euphratica community. According to the discussion above, studying prospect of reproductive ecology on populus euphratica was put forward.
