[目的]对分布于广西防城港市的3种金花茶组植物,即金花茶(Camellia nitidissima)、显脉金花茶(C. euphlebia)、东兴金花茶(C. tunghinensis) 种群的发展动态进行分析,并提出相应的保护建议.[方法] 采用样方调查法,以植株基径代表年龄,对金花茶组植物的种群规模、年龄结构进行统计分析.[结果] 结果表明,3种金花茶组植物种群都较小,分布面积和种群数量都在不断减少.[结论] 金花茶组植物种群结构显示衰退型趋势,人为干扰是导致金花茶种群衰退的主要原因.
[目的]對分佈于廣西防城港市的3種金花茶組植物,即金花茶(Camellia nitidissima)、顯脈金花茶(C. euphlebia)、東興金花茶(C. tunghinensis) 種群的髮展動態進行分析,併提齣相應的保護建議.[方法] 採用樣方調查法,以植株基徑代錶年齡,對金花茶組植物的種群規模、年齡結構進行統計分析.[結果] 結果錶明,3種金花茶組植物種群都較小,分佈麵積和種群數量都在不斷減少.[結論] 金花茶組植物種群結構顯示衰退型趨勢,人為榦擾是導緻金花茶種群衰退的主要原因.

[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.
