摘要

本文概述一對人造物視覺影響之實驗性量化分析的過程與結果。人造物的影響被視爲來自其數量及品質二因素。以此二因素爲自變數，環境品質的評價爲因變數，建立二環境品質函數。人造物數量以人造物在視野中所佔面積比例爲指標，人造物品質則考慮爲人造物色彩、形狀、質感及位置的綜合表現。建立函數所需之數據來自以照片爲表達工具的問卷調查。結果，人造物密度（卽視野中人造物所遮蔽的面積比例）的環境品質函數爲二次廻歸函數；人造物品質者爲推理曲線。

This article summarizes the process and results of an attempt to empirically and quantitatively establish the relationships between the visual effects of man-made objects and the total environmental quality Effects of man-made objects were assumed to have come from the objects' quality and quantity The former was seen as a combined measurement of the objects' colors, shapes, textures and locations relative to the elements of their surrounding, the latter was defined as the relalive area of the perceived usual field covered by the image of the objects Holding all the other factors constant, the value of total environmental quality was determined as a variable depending on the value of man-made objects' quantity or quality Data required to establish the functions were generated from surveys made with photo-graphs and questionnaires The function for environmental quality and man-made objects' quantity was simulated by a regression equation of the second degree, the other function was simulated by a logistic curve.
