Abstract |
This report describes the work done during Part II of a project which had as its aim the development of a way to quantify those intangible values peculiar to a small stream and its watershed. During the second part of the project: A method was developed whereby peoples' preferences for natural landscapes could be measured. The method utilized projected color slides and a rating system based on the semantic defferential; fourteen preference studies were conducted using different types of subjects and stimuli (color slides); the data were factor analyzed and scores computed for three factors (Natural Beauty, Force and Starkness) for each slide-subject group combination; the scenic content of each slide was measured and related to the factor scores by a series of linear regression equations; the uniqueness ratio approach was modified to include fewer stream characteristics (thirty-seven) and the work of Part I essentially repeated; and a new method of stream evaluation was developed which yields a factor score for a given stream on each of six factors (Scenic Attractiveness, Land Use-Topo, Litter, Aquatic Habitat, Extractive Industry, Development). |
