中文摘要 | 本研究的目的在於探討溪頭地區紅檜人工林樹高特性,包括樹高和胸徑之關係式及樹高生長模式,所建立之樹高曲線式以H = -36.018 + 39.397logD, R_(adj)^2 = 0.925及H = e^(3.102 - 1.698log(1/A) + 0.698logD), R_(adj)^2 = 0.955二者的表現較佳,同時研究結果亦發現加入林齡因子可提升樹高的預測效果。本研究以Mitscherlich、Gompertz和Richards三種生長模式模擬樹高生長,所得結果顯示三種模式皆有良好的模擬效果,其最大生長速率發生在幼齡期,本研究所得之結果將可提供溪頭地區紅檜人工林數量化之資訊。 |
英文摘要 | The purpose of this study is to establish the relationships between tree height and diameter at breast height (DBH), and tree height growth models for Taiwan red cypress (”Chamaecyparis formosensis” Matsum.). The study was conducted on a long term study of Taiwan red cypress plantations at Xitou District of center Taiwan, which belongs to Experimental Forest of National Taiwan University. We found that the model of H = -36.018 + 39.397logD, R_(adj)^2 = 0.925 and H = e^(3.102 - 1.698log(1/A) + 0.698logD), R_(adj)^2 = 0.955, have a good predictability. Additionally, it has been found that by adding age variable can further increase predictability for tree height. This study used three tree growth models, Mitscherlich model, Gompertz model and Richards model, to predict tree height growth. The three models have a good predictability in tree height growth of Taiwan red cypress and the maximum growth rate occurred in the juvenile period. The results provide quantitative information for Taiwan red cypress plantation in Xitou area. |
