  • Magnolia sieboldii is placed in the third class in rank of key species for conservation in China.To determine their living status,reproductive potential,ecological countermeasures and provide a theoretical basis for the conservation of this endangered plant,this paper studies the species’ dynamics and reproductive strategy of the endangered plant in four sampling sites using age class,fecundity schedule and reproductive value.The results showed that: (1) Magnolia sieboldii seedlings were less (8.8-12.3 individual/100 m2),while the number of middle aged individuals (12.0-15.0 individual /100 m2) was more than other plants. (2) The population fecundities were low and differed in the four plots,with the lowest fecundity (177.0 seed/individual) in better habitat and the highest (218.3 seed/individual) in poor habitat.(3) The maximum reproductive value increased with decreasing stability of the community,which often led to Magnolia sieboldii reaching maximum reproductive stage in poor habitat at the shortest time.(4) Ecological countermeasures of Magnolia sieboldii showed mainly the k-strategy characteristics,but in less stable community the reproductive parameters were greatly changed,showing an r-strategy characteristics.(5) Altitude,slope aspect,canopy density,and percentage of exposed rock,significantly affected the reproductive index of Magnolia sieboldii.Stepwise regression analysis showed that multiple linear relationships appeared between reproductive index of Magnolia sieboldii and environment factors, removed the moisture content of soil and litter layer.
