| 摘要: | 行道樹是都市街景的重要組成之一，通常種植位於道路兩側或道路中央之區隔帶。適時修剪行道樹可對城市道路或樹木本身具有提升公共安全、促進植栽生長發育及營造景觀美質等功能性。本研究以全興工業區之行道樹為研究材料，透過專家問卷及層級分析法評估景觀樹木修剪影響因子，結合研究者多年樹木修剪經驗，探討及示範常見之樹木不良枝修剪及實際修剪作業之應用，並對研究地區之行道樹修剪結果進行使用者滿意度評估。研究結果顯示，影響樹木修剪之主要因子為樹木存活率(第1名，權重值0.206)、修剪時機(第2名，權重值0.194)、安全性(第3名，權重值0.188)及美觀意象(第4名，權重值0.176)；而透過單一樹種修剪案例可瞭解各種不良枝之判定及剪除操作，包括幹頭枝、忌生枝、下垂枝、陰生枝、病蟲害枝及徒長枝等6種不良枝之圖文說明；而研究地區之行道樹修剪結果進行滿意度評估，其平均總分為4.27分，其結果介於非常滿意及滿意之間，顯示在景觀樹木修剪作業技術規則結合研究者多年樹木修剪經驗，不僅符合使用者需求，更可達到景觀美學及公共安全之目的，並提供木本、灌木等景觀植栽正確修剪作業之專業性、可行性與目的性。
Street trees are an important component of the urban streetscape and are usually planted on both sides of the road or in the central part of the road. Timely pruning of street trees can enhance public safety, promote plant growth and development, and create aesthetic quality for urban roads and trees themselves. This study used street trees in the Chuansing Industrial Area as the research material, and evaluated the impact factors of landscape tree pruning through expert questionnaires and hierarchical analysis, combined with the researcher's years of experience in tree pruning to explore and demonstrate the application of common tree pruning and actual pruning operations, and conducted user satisfaction evaluation of street tree pruning results in the study area. The study results showed that the main factors affecting tree pruning were tree survival rate (1st place, weight value 0.206), pruning timing (2nd place, weight value 0.194), safety (3rd place, weight value 0.188), and aesthetic image (4th place, weight value 0.176); and the pruning cases of single tree species can be used to understand the determination of various undesirable branches and pruning operations, including stem-headed branches, contraindicated branches, pendulous branches, shaded branches, and shaded branches. The pruning cases of a single tree species can be used to understand the determination and pruning operations of various undesirable branches, including six types of undesirable branches, such as stem-headed branches, contraindicated branches, sagging branches, shady branches, diseased and insect-infested branches, and long branches. The average total score was 4.27, and the results were between very satisfied and satisfied. This shows that the technical rules of landscape tree pruning combined with the researcher's years of experience in tree pruning not only meet the needs of users, but also achieve the purpose of landscape aesthetics and public safety, and provide the purpose, feasibility, and professionalism of the pruning operation of trees, shrubs, and other landscape plants. It also provides the purpose, feasibility, and professionalism of tree, shrub, and other landscape planting and pruning operations. |
