摘要

本研究主要針對嘉義市人行道上栽種的常見24種樹種，共計1,945株進行實地調查，目的在了解這些不同樹種根系的生長狀況，對人行道硬體，包括植穴邊框、鋪面與路緣石之損毀影響，以及各行道樹之樹高、胸徑與植穴面積與硬體毀損率之相關性，並探討導致根害的可能原因。於調查之24種行道樹中，香楠、青楓、緬梔及山欖等，對人行道硬體的破壞程度屬輕微，而黑板樹、阿勃勒、菩提樹，對硬體的破壞程度則趨於嚴重。不同樹種所造成之毀損程度並不相同，且對植穴邊框、鋪面與路緣石的毀損也有所差異。胸徑大小對人行道硬體的毀損呈顯著之正相關。

The purpose of this study is to understand the street tree root damage in the urban area and its causes. A total of 24 common street tree species in Chiayi City were investigated. We studied the roots growth characteristics, the damage to pavements by different street species, and their relations to tree height, DBH and tree pit size. Of the 24 street tree species investigated, 4 species (Machilus zuihoensis Hay, Acer serrulatum, Plumeria acutifolia, Palaquium formosanum Hay) caused little or no pavement damage, 3 species (Alstonia scholaris, Cassia fistula Linn., Ficus religiosa Linn.) caused pavement damage. Different street tree species also caused different levels of damages. The DHB of different street tree species and the level of pavement damage showed positive correlation.
