Analysis on Population Dynamics of 3 Kinds of Plants of Sect.Chrysantha Chang

WU Ru-hua et al(Guangxi Fangcheng Management Division of Yellow Camellia National Nature Reserve,Fangchenggang,Guangxi 538021)  
[Objective] The aim was to analyze the population dynamics of 3 kinds of plants of Sect.Chrysantha Chang in Fangchenggang City of Guangxi,i.e.Camellia nitidissima,C.euphlebia,C.tunghinensis,and put forward relevant suggestions for protection.[Method] The quadrat survey method was adopted.The ages of plants were represented by basal diameters of plants so as to analyze the population scale and age structure of Sect.Chrysantha Chang statistically.[Result] Results showed that the population of 3 kinds of plants of Sect.Chrysantha Chang were small.The distribution area and population quantity were decreased gradually.[Conclusion] Population structure of Sect.Chrysantha Chang showed a declined trend.Furthermore,artificial interference was the main cause of population decline of plants of Sect.Chrysantha Chang.
