Abstract:Based on the natural geographic data,relative slope,aspect,relative distance,visual probability,relief amplitude of terrain and vegetation pattern in forest park are taken as evaluation index factors.Using AHP method to establish the weight of each index,combining with GIS technology,the evaluation system of landscape visual sensitivity of forest park is established,and the visual sensitivity of Fuzhou National Forest Park is evaluated.Using the Yaahp analytic hierarchy process(AHP)software,we established a hierarchical structure model based on judgment matrices and derived the weight values of each indicator.The calculated random consistency ratio(CR)of the judgment matrix was 0.021,which falls within the acceptable range of CR ﹤ 0.1,indicating satisfactory consistency of the matrix.The final weights assigned to the indicators were:relative distance(0.2653),vegetation pattern(0.4295),relative slope(0.1489),aspect(0.0284),terrain relief(0.0819),and visual probability(0.0460).The ranking of indicator importance was:vegetation pattern ﹥ relative distance ﹥ relative slope ﹥ terrain relief ﹥ visual probability ﹥ aspect.The results show that the visual sensitivity of Fuzhou National Forest Park is vastly different,the main influencing factor is vegetation pattern.Within the 300-meter buffer zone along the main roads of the park,landscape visual sensitivity gradually increased with distance from the roads.Beyond this 300-meter buffer zone to the park boundary,the visual sensitivity showed a gradual decline.Assessing landscape visual sensitivity objectively can instruct the project to transform from perceptual mode to scientific rational.
