Landscape Analysis of Road Slopes in Ji-ri National Park

摘要

The purpose of this is to suggest objective basic data for the national park planning, design and management through the quantitative analysis of the visual quality included in the physical environment of the Ji-ri national park, for this, visual volumes of physical elements have been evaluated by using the Mesh Analysis, spatial images structure of physical elements have been analyzed by factor analysis algorithm, and degree of visual quality have been measured mainly by questionnaries. Result of this thesis can be summarized as fallows. Visual volumes of the naked, rock, ground cover of seed spray, and artificial planting are found to be the main factor determining the visual quality. Factors covering the spatial image of the national park roadside slopes landscape have been found to be the overall synthetic evaluation, spatial, appeal, physical, openness and dignity factors such as the overall the spatial, physical and openness yield high factor scores. As for the factors determining the degreeof visual quality of the roadside slopes, variables such as the summit, the constructions management, harmony of landscape, visual stability of road side slopes, suitable artificial planting and suitable constructions.
