摘要

森林行光合作用時，會吸收大氣中的二氧化碳，將其轉變為有機碳固定於樹木體，釋放出氧氣。人造森林若透過合理的經營管理，可提高單位面積蓄積與生長量，不但為生態材料的有效供應來源，且可促進大氣中二氧化碳的吸存，達到永續森林資源發展的目標。
本研究採用問卷調查法，以中小學生家長為問卷調查對象，以探討大眾對於人工林的認知情況，對於木材利用與環保之間是否存在著錯誤的連結。本研究所使用之工具，為自編的「大眾對於人工造林木利用之認知調查」，問卷分成下列四部份：「台灣林業現況」、「人工林的認知」、「木材利用與環保」、「木材的認知與喜好」，均以以四點量表為度測之規準。第四部分後面另有 4 題調查性題目，分別調查受訪者「居家環境木材內裝情況」、「優先考量木材內裝的種類」、「綠建築」以及「使用國產材製課桌椅」之看法。
此次調查所回收的問卷資料經分析之後，可得出以下幾點結論：
一、 大眾對於森林之功能，以及木質材料的優點均持正面的看法；對於「人工林」、「天然林」、「造林」等名詞，一般民眾雖然不感陌生，但對於其內涵卻不甚清楚；問卷中所預設之反向題的填答結果，也顯示出大眾對於人工林、木質材料、以及人工造林木之利用，仍存有錯誤的偏見。
二、 問卷的四個分量表對於總量表得分的相關性與迴歸解釋力均達顯著水準，其中以「人工林的認知」分量表與總量表之相關性最強，R2 達.740。
三、 受試者背景變項對於4個分量表及總量表之預測能力均達顯著水準，但預測值偏低；利用逐步分析法得知，對於「台灣林業現況」、「人工林的認知」與「大眾對於人工造林木利用之認知調查」量表得分，最具預測力的變項均為「生態節目」。

When photosynthesis proceeding, trees can absorb the carbon dioxide in the atmosphere, and transform it to the organic carbon with fixing to the wood, and releasing the oxygen at the same time, If we can manage the plantations with the reasonable methods, that may enhance the storage and the growth quantity of the unit area of the plantations. Not only the effective supply for the ecology material, but also may promote CO2 sequestration in the atmosphere, achieved the goal of the sustainable use of the forest resources.
This study adopts the research methods of a questionnaire survey. We take the guardians of the elementary and middle school students as the questionnaire survey objects to discuss the cognition of the general public regarding the plantations, and to see if the public had a wrong linking between wood use and environmental protection.
The implement of this study is "the general public’s knowledge toward the use of wood from the plantations", organized by the researcher. The questionnaire divides into four parts as the followings："the present situation of Taiwan forestry", "the cognition of the plantations", "the wood use and the environmental protection", "the cognition and preference of wood ", Each item is measured by 4 points type of Likert’s scale. There are 4 investigative items after the fourth part. The purpose is to know the thoughts of the participants about "the situation of the wooden material decoration in the house environment", "the precedence of the types of the wooden material decoration", "the green house" as well as "the opinion of using the class furniture made of domestic timbers".
After analyzing the data from the returned questionnaires, we get several conclusions :
First, the general public have the positive attitude of the function of the forest and the advantage of the wooden material. Although the words and phrases, like "the plantations", "natural forest", "afforestation" are not unfamiliar to the common populace, the inner meanings of those words are not really understood. The answers of the negative items designed on purpose also demonstrated the populace still had the wrong prejudice against the plantations, the wooden material, as well as the use of the timbers from the artificial forest.
Second, the four subdivisions which have reach the remarkable level in statistics have the good capability to estimate the scores of the whole questionnaire, and there are correlation between the four subdivisions and the questionnaire, “The cognition of the plantations” has the strongest correlation with the whole inquiry. The value of R2 reaches .740.
Third, regarding 3 investigative questions as the background variables to carry on the regression analysis, we discovered that "the wood use and the environmental protection", "the green house" as well as " the opinion of using the class furniture made of domestic timbers" 3 items have the promotion to the capability of interpretation of the scores.
