摘要
摘要 市郊森林係指都市行政區內，位於都市密集發展區域邊緣的森林。在台灣，市郊森林多位於都市外圍的山坡地或丘陵，因此常具有下游人口密集區域水土資源保護與災害防止的功能，加以該區保留大量自然綠地，保存許多植種與物種棲息地；此外，該區為民眾休閒遊憩與運動以享受自然的地區，深具心靈與美學的功能。兼具保安、生態保育及休憩功能的市郊森林，在過去由於都市發展未逼近該區，因此重視的程度不高，然在發展的趨勢擴張到這些區域時，原屬緩衝的農業區消失，並且發展深入到市郊森林的區域，造成這些區域的壓縮以及破碎。藉由對於市郊森林的功能性分類，可以對照出這些區域在各功能上的分佈與變化，以此可以在規劃與發展都市時，仍不忽略深繫居民生活品質、安全與生態的市郊森林。 根植於上述功能的分類系統，依據現有的保安林劃定準則、都市使用分區與近鄰關係以及景觀生態的原則，藉此逐步完成細分的分類。配合現有的台北市都市使用分區管制圖、正射影像圖以及其他輔助圖層，即可得到臺北市市郊森林的功能性分類。 【關鍵詞】市郊森林、保安林、土地使用分類

Abstract This study attempts to develop a classification to divide the suburb forest according to their services or function. Here suburb forests refer to which locate outside or close to urban intensive developed area within a city administration boundary. In Taiwan, we find most of suburb forests on the mountains or hills which surround on the urban fringe, thus these forest, to some extent, protect the downstream urban area from natural disasters, maintain water resource and conserve the habitats for wide lives. Besides, citizens hold recreation activities in this area to relax and get spirit comfort. Suburb forest was not paid much attention and when the developed area expands, these forests together with nearby agricultural zone was changed or fragmented to residential or other usage, causing them compressed or eliminated. I think if a suburb forest classification is created and mapped out, this might be help to understand how they spread out on the urban landscape and how they should when it comes to urban planning. The classification was constructed in accordance with tree main function- disaster protection, habitat conservation and recreation activity. I use the available disaster protection forest designation criteria, urban zoning, spatial relation and landscape ecological principal to formulate the category and with the latest Taipei city zoning map, aerial orthoimages and other auxiliary information to find out how they distribute in the Taipei’s landscape. Keywords: suburb forest, protection forest and land use classification.
