屏東市行道樹植栽綠化問題之探討
A Study on the Roadside planting in Pingtung City
摘要
本研究之動機為研究道路行道樹在規劃設計與維護管理上常遇到的問題，並針對問題做探討，於2009年2月到5月間，以田野調查法方式，調查屏東市區行道樹植栽的物種多樣性、綠化上常發生的問題，並依據調查結果提出建議，摘要如下： 屏東市區主要道路行道樹植栽調查分析發現，選用喬木植栽種類有33種，其中13種為原生植物，20種為外來植物；灌木植栽種類有15種，其中11種為外來植物，原生植物只有4種被選用；地被草花調查發現只有7種，且大都是外來種植物，而蔓性藤本植物種類只有2種，在整體植栽選用變化不多。 綠化問題主要分為規劃設計與維護管理兩方面探討，調查發現規劃設計在植栽配置、植栽穴、周遭建築物關係最容易發生問題，維護管理方面主要在日常維護、整枝修剪、支架設立與病蟲害等問題發生。 希望藉由屏東市區行道樹植栽的案例實證，探討綠化問題主要發生原因與改善方式及建議，期望未來能提供景觀設計及管理單位之參考。

It is indicated that there are 33 species of tree planting in the investigation and analysis of main roadside plants in Pingtung City. Among these, 13 species are native plants and 20 species are exotic ones. There are 15 species of shrub planting and among these, 11 species are exotic species and only 4 native ones selected. In the investigation, only 7 species of ground cover plants and flowers are found and most are exotic plants; there are only 2 species of climbing plants and therefore the application on overall planting is limited. The greenery problem is discussed mainly in terms of two aspects: design and maintenance management. It is discovered that planting layout, planting holes and surrounding buildings bring most problems while planning. In the aspect of maintenance management, the problems mainly happen in daily maintenance, trimming, crutch establishment, blight and insect pests. It is hoped that through the case of roadside planting in Pingtung City to study main reasons causing green problem, improvement and recommendations for future reference to landscape design and management units.
