景觀是人類認知與知覺活動的對象，也表徵(represent) 著人類生活實踐
的場所以及維生的系統。它是一種適意性資源，也是一種遊憩資源、精神
資源和歷史資源，並且具有不可再生性。因此有必要將特殊和重要的地景
資源加以保育，以免因受不當開發而破壞。本研究以「區域景觀分析」的
方法，對大範圍的研究區進行景觀調查。首先探討景觀分區、景觀單元劃
設、航照判釋和景觀評估等的理論和方法，並以此為基礎，提出區域景觀
分析的準則及實作流程架構。同時，依據提出的準則及分析架構實際應用
在研究區－花東海岸山脈南段。景觀分區系統可由高而低分為連續景觀、
景觀區帶、景觀單元及景觀元素四個階層。實際作業則以航照和地形圖為
主要的空間分析工具，輔以地質圖、水文圖、坡度圖、土地利用圖等其他
資料。根據景觀空間特性、封閉性、地形明顯特徵、景觀統一性等經過室
內地圖分析、野外初步調查、航照初步判釋、地面調查、航照最終判釋等
分析流程，將海岸山脈南段劃分成九個景觀單元（Ⅰ∼Ⅸ）；各個景觀單
元根據地形坡度、土地覆蓋種類（自然植被及人為土地利用）等，再細分
成八類景觀元素(1A、1B、2 A、2B 、3A、3B、4A、4B) 。並且也利用景
觀評價表格，依景觀美質評估項目（包括：統一性、生動性、繁雜性、稀
少性及完整性等），對各景觀單元進行描述與評估。根據這些步驟，可認
識研究區內景觀特徵和分佈的相關性。根據研究成果得知： 1.「景觀分
區」的理念和方法具有系統性、周密性及有效性，適用於區域景觀分析的
調查和研究。景觀分區所得的結果可以作為從事保育與開發決策的基礎
。 2.航空照片具有許多特性，可以部分取代地形圖、水文圖、植被圖、
土地利用圖和野外調查等。對景觀的分區和描述等，航照有很大的用處。
在景觀資源的調　查和過程中，它是一種不可缺少的工具。 3.海岸山脈
南段具有山嶺景觀、河流景觀、山間盆地、泥火山、泥岩惡地等，兼具小
規模和大規模及自然和人文的景觀特色。 4.控制區域景觀特性的因子，
包括了地質條件、地形作用等，還有人為的開發利用程度。

Landscape is a non-renewable, recreational, spiritual,
historical, and practically finite resource. Consequently,
visually outstanding and scientifically significant landscapes
must be preserved from development. In a study of regional
scale,economical and effective method to select sites and
decide boundaries becomes critical. This study reviewed
previous theories and methods about landscape classification,
and the concepts of landscape unit, air-photo interpretation,
and landscape aesthetic evaluation. Landscape classification
and landscape unit concepts do appear to offer a logical and
useful framework for description and evaluation. Obviously,
these methods can divide regional landscape into coherent,
spatially-defined units. In this study, the southern section of
the Coastal Range was divided into nine landsacpe units
characterized by their uniformity invisual experience, spatial
structure of landscape, topographic encloure, dominant feature,
and landscape homogeneity. Moreover these units arefurther
subdivided into eight different landsacpe elements based on
slope steepness and landcover ( natural vegetation and landuse)
types. Then, each landscape unit was evaluated by considering
such aestheticcriteria,namely unity (or harmony and continuity),
vividness(or diversity and richness) ,scarcity and intactness.
This study was made by using aerial photographs, contour
maps readings, slope data analysis, and supplemented by field
checks and field mapping techniques. The result of this study
is presented on a landscape unit map, a series of landscape
element maps,and tables which evalute and describe landscape
elements and landscape aesthetics. It is clear from this study,
that regional landacpes of the southern Coastal Range are under
the control of lithological and structural factors,
geomorphological processes, and human interference.
