摘　　要：为了解小黄花茶种群生态学规律,利用不同的生态数据,对种群的环境条件、空间结构、年龄结构进行观测分析。结果表明:1)保护区内有少量的小黄花茶被砍伐,但种群结构较稳定,当前破坏干扰程度不明显;2)小黄花茶的空间分布格局,除P4试验样地为集群分布外,其余均为随机分布;3)小黄花茶种群在不同年龄结构上以小径级个体相对较多,大径级个体则较少;通过幂回归方程和生存曲线可知,P3试验样地的小黄花茶种群属增长型种群,P1、P4、P5样地的种群属稳定型种群,P2、P6样地的种群则属衰退型种群。The habitat,spatial structure and age structure of Camellia luteoflora population were analyzed by different ecological data to know the regulation of population ecology in Guizhou.The results showed that a small number of Camellia luteoflora were cut in the protection zone but the population structure was stable,the spatial distribution was a random distribution pattern except for P4 experimental plot,and there were more individuals with a small diameter in Camellia luteoflora population.The Camellia luteoflora population in P3 plot belongs to an increasing population pattern.The Camellia luteoflora population in P1,P4 and P5 plots belongs to a stable population pattern and the Camellia luteoflora population in P2 and P6 plots belongs to a declining population pattern.
