| 摘要: | 生態足跡分析法是評估、規畫永續性的工具，用來分析人類生活消費對環境衝擊的程度，以換算土地面積做為比較基礎，算出土地類型所消耗的能量和經濟，知道土地面積是否能維持目前的生活品質或需改善，讓聚落達到環境、生態、經濟三者之平衡，朝永續發展方向邁進。現在商業活動頻繁、聚集大量人口，人類活動所消耗的資源和產生的廢棄物隨之增加，而將超出環境和土地的承載量，一旦對環境和土地造成傷害，需要恢復原貌的時間難以估計。
本文引用加拿大學者所修改後的生態足跡分析法，以2010年全臺的統計為依據，得到65種作物品項回歸式，並此推估2011年大台北地區的生態足跡，得知要為大台北的生態足跡應該要減少耕地、牧場地、建築地、交通用地的面積，增加森林用地、碳吸收地的面積。
在回歸分析過程中，得到13種作物品項的回歸式，發現當面積增加、生態足跡也會增加；反之，其他糧食、香蕉、鐵路以電力為能源、鐵路以柴油為能源，當面積增加、生態足跡會跟著減少。並透過與前人研究比較，得知各類生態足跡的趨勢。本研究成果已成功地，評估台灣生態足跡對環境、生態的影響。
Ecological footprint is a tool to assess and plan sustainability. It is often used to analyze the extent of human consumption impact on the environment , to compare and calculate the economics and energy consumption of different land uses, and to judge whether our living quality is being maintained or improved. Settlements can affect the balance among environment, ecology, economics and sustainable development achievement. Frequent commercial activities have resulted in larger population growth. Resources consumption of human activities may create waste increase. When the land carrying capacity is overly exceeded, the environment will be extremely difficult to restore. This study assesses ecological footprint and uses Great Taipei's areas as the study site. We divide land use type in seven classes: cultivated land, pasture, building land, forest, transportation, territorial water, and carbon absorption land. These classes further subdivide into three categories according to their land area sizes to compute for their ecological footprint values. We can then obtain ecological footprint value for the entire Great Taipei's areas.
In regression analysis, regression get 13 kinds of items as items found when the area increases, the ecological footprint will increase; Conversely, other grains, bananas, railway electricity as energy, rail diesel for energy, increased when the area, will be followed to reduce the ecological footprint. And by comparing with previous studies, that the trend in all kinds of ecological footprint. The results have been successfully assess the impact of Taiwan's ecological footprint on the environment and ecology. |
