| 摘 要： | 中国沙棘虽然属于阳性树种,但它能够通过克隆生长调节恢复种群数量和结构,从而维持种群的稳定性和持久性.随着种群年龄的增大,种群结构表现为增长型、稳定型、衰退型、稳定型(或增长型)的动态过程,种群密度及萌蘖根的生物量投资比例表现为增长、下降和回升的动态过程.形成这一动态的原因,主要归结于克隆生长所赋予的生理整合与觅养行为等特殊性. |
| 关 键 词： | 中国沙棘 克隆生长 密度调节 结构动态 稳定性维持 |

| Abstract: | Hippophae rhamnpides L. subsp, sinensis belong to a heliophile tree, but the population can maintain its stability and enduring with the recovering of density, biomass and structure by clonal growth regulation. As the increasing of population age, the structure of population is characterized by a transformation from an increasing type through a stable type to a declining type, and then turn into a stable type or increasing type. Density, biomass and the investment rate of biomass of spacers show a dynamics process from increasing to declining, and then turn to be recovering. The reasons for above results are mainly the physiological integration and foraging behavior as a result ofclonal growth. |
| Keywords: | Hippophae rhamnpides L ssp sinensis clonal growth physiological integration density and biomass regulation structure dynamics stability maintenance |
