中文摘要 | 本試驗調查高雄六龜與台南白河地區麻竹(Dendrocalamus latifl orus)林分之生長及生物量。麻竹林分生長分布特性方面,兩地區之林分株數頻度皆以胸徑6 ~ 8 cm者佔最多;竹叢分布面積與林地面積比例,白河樣區之22.2 ± 0.6 %較六龜樣區之7.5 ± 3.6 %高;六龜樣區之竹叢數及竹稈數分別為每公頃111 ± 38叢(clumps ha^(-1))、1,117 ± 232稈(culms ha^(-1)),竹叢數及竹稈數皆較白河樣區每公頃330 ± 60叢(clumps ha^(-1))、7,267 ± 643稈(culms ha^(-1))低,六龜樣區之竹叢稈數14 ± 3稈(culms clump^(-1))較白河樣區22 ± 2稈(culms clump^(-1))少,但六龜竹叢大小為7.7 ± 5.0 m2 clump^(-1),較白河樣區7.2 ± 0.2 m2 clump^(-1)大,六龜樣區之竹叢分布較不均勻;林分生長性狀方面,兩試驗地之平均胸徑差異不大,六龜與白河樣區分別為6.9 ± 2.6 cm、7.3 ± 1.7 cm,而六龜樣區之平均竹高為12.4 ± 3.5 m較白河地區之8.8 ± 1.8 m高;地上部乾重方面,六龜樣區因竹叢稈數低且竹叢數少,其地上部林分總生物量亦遠低於白河樣區,六龜與白河樣區之總生物量乾重分別為17.4 ± 2.7ton ha-1、94.5 ± 8.4 ton ha^(-1),其中六龜樣區各齡級之生長及生物量結果,4年生及以上之總生物量最高、且隨齡級遞減而減少,六龜麻竹林明顯出現生長衰退的現象。 |
英文摘要 | This study investigated the plantations of ma bamboo (Dendrocalamus latiflorus) in Liukuei, Kaohsiung and Baihe, Tainan. Results show that, the frequency of bamboo culms both sites is the highest at 6 ~ 8 cm DBH class. The ratio of crown land area to bamboo, 22.2 ± 0.6% in Baihe is higher than 7.5 ± 3.6% in Liukuei. The number of clumps and culms are 111±38 clumps ha^(-1) and 1,117±232 culms ha^(-1) in Liukuei, 330 ± 60 clumps ha^(-1) and 7,267 ± 643 culms ha^(-1) that higher than in Baihe, respectively. The number of culms at 14 ± 3 culms clump^(-1) in Liukuei is lower than the number of culms at 22 ± 2 culms clump-1 in Baihe. But the size of clump at 7.7 ± 5.0 m^2 clump-1 in Liukuei is bigger than the size of clump at 7.2 ± 0.2 m^2 clump^(-1) in Baihe. The distribution of clumps in Liukuei is uneven. The average of diameter is not signifi cant between experimental sites. It is 6.9 ± 2.6 cm and 7.3 ± 1.7 cm respectively in Liukuei and in Baihe. The average hight of 12.4 ± 3.5 m in Liukuei is higher than 8.8 ± 1.8 m in Baihe. The above ground biomass, the amount of culms and clumps in Liukuei is lower than in Baihe. The above ground biomass in Liukuei and Baihe are 17.4 ± 2.7 ton ha^(-1) and 94.5 ± 8.4 ton ha^(-1), respectively. The above ground biomass of Liukuei at different age indicated that the old bamboo which is above age 4 is the highest on above biomass. The biomass of bamboo decreased gradually from age4 to age1. It appeared the symptom of recession in Liukuei. |
