中文摘要 | 本研究旨在以柳杉(Cryptomeria japonica D. Don)之胸徑為探討對象,建立臺灣地區不同柳杉林分生長情形之比較基準。由於不同地區之林分胸徑生長情形一般僅能比較其大小之差異,本研究經蒐集並計算臺灣地區柳杉胸徑之平均與其餘9個百分等級(percentile rank, PR)之值後,並採用Schnute生長模式模擬各等級之5至100年生胸徑生長表現曲線組。透過本曲線組將可更判斷不同地區之生長情形所屬之等級,可詳細探討臺灣地區各柳杉林分之生長表現優劣及作為林分經營之參考基準。 |
英文摘要 | The objective of this study was to establish a comparison baseline of diameter at breast height (DBH) growth in Japanese cedar (Cryptomeria japonica D. Don) plantations in Taiwan. Traditional measurement data of DBH in different plantations can only compare the sizes. In this study, we simulated the mean and other 9 percentile rank (PR) of DBH from age 5 to 100 years to establish the DBH growth curve groups by using the Schnute growth model. By using the DBH growth curve groups will be able to distinguish the different level of DBH growth, and more detailed comparison of the growth of different plantations of Japanese cedar in Taiwan. |
