在高密度發展的都市環境中，線性綠化能為破碎的綠地帶來實質串聯。以臺灣舊市區巷弄為例，扮演著和公共開放空間同等重要的角色，是居民生活、交通連結、城鎮景觀特色與歷史文化活動發生的地點。但是，巷弄綠化普遍受到規劃政策的忽視，又欠缺基礎研究支持有效的規劃行動。因此，本文的目的是瞭解都市更新地區的巷弄綠化現況，與巷弄特性之間是否具有關聯性。普查紀錄嘉義市更新地區的所有巷弄，並分析其綠化方式及空間特性之間的關係。結果顯示巷弄綠化的存在，主要是與巷弄本身的空間形式及巷弄空間的活動使用方式有關，但是與兩側的建築類型和土地使用方式較無關。巷弄的種植型態，則與四種巷弄特性因子皆有關連性。

In highly developed compact urban environments, linear greening can bring physical connection to fragmented green spaces. In Taiwan, those alleys in inner urban areas play a role as important as public open spaces. They are places where urban inhabitants' daily life, connecting transportation, townscape characteristics, and historical and cultural activities take place. However, alley landscaping is often neglected by planning policies. There is a lack of fundamental research to support effective planning actions. Thus, this article aims at understanding the relationship between alley landscaping and alley features in urban regeneration areas. All alleys and lanes in the designated regeneration areas in Chiayi City were documented, and the associations between the factors of their landscaping typology and spatial features were analyzed. The results show that the existence of alley landscaping is mainly associated with the spatial pattern of alley itself and the activities in the alley space, but less associated with the type of buildings and the land use alongside. The planting typology is associated with the four features of an alley or a lane.
