碩士 === 國立臺灣大學 === 森林環境暨資源學研究所 === 101 === There are many plantations of Cunninghamia lanceolata in the early period of Taiwan. It has been used as forest products in the same time. Although there is much literature on the subject of the growth of Cunninghamia lanceolata plantation, it’s lesser research on growth comparison. There are many plantations of Cunninghamia lanceolata in existence in China also. This study selected data of literature or field survey, and established the mean growth curves of the stand DBH, stand tree height, stand density, stand basal area and stand stock in two countries, and then applying models to fit mean growth curves. The result reveals it has high similarities on the mean growth curve of DBH when Cunninghamia lanceolata plantation is in the young and middle-age period. The simulation effects of Schnute growth model are much better than other models. Besides, when we use stand basal area as an independent variable to estimate the stand stock, the coefficient of dertermination can reach about 0.89. This result will help us predict the stand stock.
