Abstract: The population dynamic of Castanopsis carlesii in Wuyishan Nature Reserve was studied and their age structures, the life table, survival curve and dead curves were analyzed.At the same time, the population dymamics were analyzed by spectral analysis method. The results showed that the C. carlesii population in Wuyishan Nature Reserve was a progressive or stable type. The number of young-age individuals was more than that of middle-age and old-age individuals. The population density differed amongdifferent altitudes,and the population C was the biggest. The life tables showed that the death rates at age class Ⅰ and Ⅱ were higher, and with the diameters class increasing, the death rates were decreasing. However, at age class Ⅳ and Ⅴ, the death rates increased again. The expected life of age class was higher before class Ⅳ, with age increasing, the expected life decreased gradually. The type of the survival curves of different population was close to Deevey Ⅲ. The spectral analysis of the population dynamics of C. carlesii was made, which showed that there was a marked regularity of periodic fluctuation in the process of natural regenration of C. carlesii.
Key words: age structure, life table, survival curves, spectral analysis
