校園綠林周邊地表之熱像解析-以中原大學楓香詩園為例

植栽可以提供陰影、控制風量，調節溫度、增加美觀及滿足人對自然景物的心理需求，紅外線熱像儀（Thermo-tracer）是一種非接觸式的高感度紅外線偵測器，在許多科學領域上之運用相當普遍，可利用此儀器觀察物體表面的溫度變化；當然，也可用此儀器來觀察植栽與建築物表體溫度變化及分佈的狀況。本研究利用紅外線熱像儀的特點和功能，探討校園植栽綠林對微氣候之影響。本研究為一實證研究，其執行步驟為：1.利用熱像儀不同地表面材溫度變化之差異，進行定期定點觀察及熱像記錄；2.在各測點之歷時性分析圖中，看出戶外空間之空氣溫度、地表鋪面溫度及日射之影響，找出微氣候的變異；3.進行綜合調查之數據分析，比較與討論，並做成結論。主要結果為：1.綠林與校園局部熱環境之關係；2.綠林周遭地表鋪面之溫度行為解析。

Planting trees can create shade, control the volume of wind, moderate temperatures, please the eye and fulfill the need for natural landscapes. Thermo-tracers are highly sensitive, non-contact, infrared detectors widely used in various scientific applications. This instrument can observe temperature distribution and change on the surface of plants, buildings, and other objects. This study used thermo-tracers to examine the microclimatic impact of plants and forested areas on the main campuses of Chung Yuan Christian University. The steps of this empirical study are as follows: 1.differentiating the temperature changes in various surface materials with thermo-tracers, by regularly observing thermal image records in testing sites; 2.measuring microclimatic changes under the influence of the sun, with historic analysis of charts of surface and air temperature from each testing site; 3. performing comprehensive data analyses, comparisons, and discussions. As the results are: 1. identifying the relationship between forested areas and partial hot environments within the campus; 2. gaining an understanding of temperature change on surface materials surrounding the campus green woods.
