Abstract:
The growth parameters,clonal propagation parameters and sexual reproduction parameters of Acanthopanax giraldii population were systematically investigated and analyzed by means of population ecology in this study. The correlation among the above mentioned parameters and the correlation among canopy density,topography and soil fertility factors were analyzed. It is clear that there was a significant correlation among the clonal ramets,the fruit production capacity of the cluster and the new shoot production capacity of the A. giraldii. Sexual reproduction and clonal reproduction played an important role in the continuation of the population. Illumination was the key ecological factor that determined growth type. The increase in canopy density changed the population from " group clonal growth" to " guerrilla clonal growth",and the higher stand closure degree and low-strength herb layer competition was a necessary condition for seed germination and colonization. Under the background of natural forest protection and sustainable development of resources,the reproductive characteristics of wild A. giraldii resulted in the decrease of its recoverable quantity.
