摘要

日據時代日本人興建林場鐵路，大量砍伐台灣的原始森林運回日本，光復後政府為了外匯大量開採林木外銷，其後為了推動十大建設不少林地遭到破壞，再加上政府在民國七十二年開放山坡地老丙建土地的開發，已造成台灣寶貴綠林快速的消失，影響自然生態環境極大。政府在推動各項公共工程建設時，雖有利於民生，唯施工總會造成綠林區的破壞，如沒要求作好綠林保存及納入回饋，綠林區就會愈來愈少。回顧政府公共工程綠美化的政策及全民對綠林保護的期待，皆顯示政府公共工程應執行綠林回饋已是必然的趨勢，但仍缺乏完整的綠林回饋評估機制。由問卷調查的統計分析，更確認綠林回饋為社會大眾的共識及研究主題方向。本研究運用功能分解及模式模擬設計，找出影響綠林回饋因素及評估要項，依區域的特徵屬性劃分各綠林區塊，進行客觀的預算模擬評估，以對綠林回饋的預算需求進行分析，選取七個不同屬性的案例，進行實地拍照，依屬性劃分不同的模擬區塊進行分析，再依草地區、花草區及樹木區等不同屬性劃分各種類型的綠林，說明模擬評估架構與計算方法及實作，以利協助公共工程綠林回饋的預算規劃評估作業。

The disappearance of green forest and trees has become a serious concern resulting from the massive consumption of wood dating back the railroad construction during the Japanese colonial times to the Ten Major Infrastructure decades ago and substantial wood products exported worldwide. Furthermore, since 1983, the Government has decided to release previously designated construction land that continue worsening the disappearance of green forests and seriously damage natural ecological environment. The Government has initiated a wide range of public construction projects. Although such projects can benefit citizen’s livelihood, they, simultaneously, can damage preservation of trees and cause fast disappearance of green forests. In assessing current systems in public engineering, policies in greening, and public awareness of sustaining trees and forests, it appears that the Government needs to consider making greening feedback a mandate in public engineering. By undertaking a survey questionnaire and statistical analysis, this research confirms that greening feedback as a research focus can help raise the awareness of the general public towards this important environmental issue. This research applies functional decomposition and simulation analysis design to identify greening factors and assessment criteria, investigates simulated budgetary design to rebuild trees and forests, categorizes greening areas based on property characteristics, and evaluates budgetary needs for greening construction. These proposed action plans should help the Government to incorporate greening budges in construction planning during initial operations of planning. that can help restore and rebuild diminishing forests to achieve the goals of sustainability and survival of humankind and nature. Select seven case studies, from simple to complicated, to help facilitate the planning and budgeting of greening feedback in public constructions. Each case study will display pictures taken from each site; evaluate each simulated area based on the categories of grass, flowers, and trees; and describe assessment methods and associated elements、structure and implementation.
