摘要

本研究為針對臺灣中部臺大實驗林對高岳營林區94年生柳杉人工林分析其生長模式並估算碳存量。五種生長模式模擬胸徑與樹高結果顯示，其決定係數分別介於0.935-0.995及0.914-0.946間，並以Mitcherlich、Gompertz及Richrads三種模式有較好的模擬。經推估後地上部碳存量為377.2 ton ha-1，平均每年地上部碳存量為4.44 ton ha-1或是每年吸存二氧化碳16.28 ton ha-1，此一結果將能提供預測柳杉人工林生長過程，並可為未來森林經營管理提供重要參考依據。

The purpose of this study was to analyze growth model and estimate the aboveground biomass and carbon storage of 94 year old Cryptomeria japonica D. Don plantation on Duie-Guo-Yue area of the experimental forest, NTU in central Taiwan. The results showed that the determination coefficient of DBH and tree height fitted by five growth models were from 0.935 to 0.995 and 0.914 to 0.946, respectively, and Mitcherlich, Gompertz and Richrads models have better fitting results. The aboveground biomass production was 377.2 ton ha-1, the average annual aboveground biomass production was 9.04 ton ha-1yr-1 estimated by function of standard stands, and carbon storage in aboveground of trees estimated was 4.44 ton ha-1yr-1 or 16.3ton ha-1yr-1 CO2. These results will support the prediction of growth process and management of Cryptomeria japonica D. Don plantation.
