摘要

森林景觀視覺化是指在森林環境中，透過實體或抽象之影像將實物或虛擬物體之形體利用電腦繪圖技術表達出來之方法與過程。景觀視覺化處理之優點在於對人類而言，與其它媒介（如文字或符號）相比，視覺影像容易被人感受，進而幫助人類能較容易地瞭解複雜之現象與過程。本研究使用近年來發展出之三度立體空間電腦繪圖技術（3D CG），結合扇平生態科學園核心地區之地型、建築物、植被空間位置和實物調查資料，以Google SketchUp 3D建模軟體進行物件之模擬和景觀之配置，並透過Google Earth平台將模擬和配置結果以動態或靜態影像方式表示。研究成果顯示使用電腦模擬所得之影像除與實體有高度之相似性外，還可經由本研究發展出之森林景觀視覺化處理技術平台，在電腦前進行研究地區之導覽和體驗在規劃區進行即時漫步（walk through）之機會。由於電腦之高速效率，民眾可使用森林景觀視覺處理平台進行不同情境設計之模擬和評估，此技術預計未來可提供國內森林相關之產業或遊樂區使用來改善現有之森林景觀。

Forest landscape visualization involves the rendering of realistic or abstract images that represent an underlying dataset of forest environments. The dataset may be the product of physical measurements of the real world, or it can be the product of a computational model. Visual images are regarded as being relatively easily interpreted by humans and help people understand complex data and processes. This study used a 3D computer cartographic technique to compile data of the terrain, buildings, roads, and plants in the core area of the Shanping Ecological Scientific Garden (SESG) in the Liukuei Research Center, southwestern Taiwan. SketchUp software was used to build 3D object models and assign allocation to the objects based on a geographic survey. Keyhole Markup Language and Google Earth were also used to generate digitized virtual scenery images. With the aid of the forest landscape simulation system we developed, people could quite easily visit the virtual world of the SESG at home. Finally, 2 scenarios of nursery management in the SESG were designed in this study. It is expected that the 3D simulation technique developed in this study can be utilized in forest recreational areas to design scenarios and elicit public discussion on landscape planning.
