Evaluation of Landscape Visual Sensitivity of Mount Wuyi National Park Based on GIS
Landscape visual sensitivity is a measure that reflects the degree of attention of landscape within the scope of vision,which can avoid landscape damage and resource waste caused by blind development.Taking Mount Wuyi National Park as the research object,using the spatial analysis function of ArcGIS technology,five sensitivity indicators,namely,relative slope,relative sight dis-tance,visual probability,striking degree and scope of vision,were selected to build a visual sensi-tivity evaluation system,the spatial distribution of the visual sensitive areas of each indicator was clarified,and then the indicators were weighted by normalization processing.The final results showed that the visual sensitivity of Mount Wuyi National Park was obtained in a distribution pattern of high in the east and low in the west.High visual sensitivity was mainly distributed in villages,scenic spots,streets and other areas.The proportions of the study area categorized into low,medium-low,medium,medium-high and high sensitivity zones were 48.29%,9.05%,21.07%,14.19%and 7.40%,respectively.
