| 摘要: | 民雄工業區為民國67年初開發之綜合工業區，至今已有40餘年，面積達244公頃，園區內進駐廠商多元化，目前行道樹在工業區綠蔭覆蔽。工業區內行道樹之樹種約20餘種、數量3千餘棵，主要以喬木為主，園區內行道樹根系破壞地下管線、溝渠、人行道舖面及落葉頻率高。經常性修剪整飾維護，維護人工及整飾費用日易增加，評估工業區適合種植之行道樹有其必要性。 本研究以現有行道樹資料庫結合層級分析法(AHP)進行樹種篩選因子「景觀意象」、「經濟價值」、「維護管理」、「原生樹種」及「生態保育」之評估，並透過專家問卷評估所得之權重值前3名分別為維護管理(權重1.4259)、景觀意象(權重1.2608)及原生樹種(權重1.0364)做為篩選園區內最適樹種，主要有樟樹、茄苳、榕樹、台灣欒樹、苦楝、菩提樹、光臘樹等，做為選擇適合民雄工業區種植之樹種，作為未來工業區綠美化補植之參考，並可減少整修蟲害、養護成本等問題。
Minxiong Industrial Zone is a comprehensive industrial zone developed at the beginning of 1978. It has been more than 40 years and covers an area of 244 hectares. There are diversified manufacturers in the park. At present, the roadside trees are covered by greenery in the industrial zone, which has various functions such as beautification and air conditioning. There are more than 20 species of street trees in the industrial zone, with a number of more than 3,000 trees, mainly arbor. The roots of street trees in the park destroy underground pipelines, ditches, sidewalks, and fall leaves with high frequency. Regular pruning, finishing and maintenance, as maintenance labor and finishing costs are increasing day by day, it is necessary to assess the roadside trees suitable for planting in industrial areas. This study uses the existing street tree database combined with the hierarchical analysis method (AHP) to evaluate the tree species selection factors “landscape image”, “economic value”, “maintenance management”, “native tree species” and “ecological conservation”, and evaluate it through expert questionnaires The top 3 weighted values obtained are maintenance management (weight 1.4259), landscape image (weight 1.2608) and native tree species (weight 1.0364) as the most suitable tree species in the screening park, mainly camphor tree, Bishopwood, Banyan, Taiwan luan, Neem tree, Bodhi trees and wax trees, etc., are selected as suitable tree species for planting in the Minxiong Industrial Zone, as a reference for greening and replanting in the future industrial zone, and can reduce the problems of repairing insects and maintenance costs. |
