Landscape Visual Quality Assessement Based On ASG Integrated Approach

Landscape evaluation theory and practice began in the1960s, with the development of landscape architecture, landscape assessment study area is also wider, and more widely, for different landscape types, landscape-scale and even different regions. Landscape has studied the practice and theory.This paper presents the concept of visual quality of the landscape, creating a landscape assessment based on ASG integrated approach, the establishment of a theoretical framework for evaluation of the visual quality of the landscape, and through the Heilongjiang Province Crater National Forest Park was evaluated to verify the feasibility of the concept and theory resistance and operability.On a clear definition of the concept of landscape visual quality assessment, the visual characteristics of landscape will be significant, the user’s feelings will into the evaluation process, establishing an evaluation framework based on visual characteristics.based on ASG integrated approach evaluation methods, namely a combination of the respective evaluation advantage AHP, SBE method, GIS systems, using AHP to establish evaluation index weight, use SBE method using data to measure people’s subjective landscape perception, the use of GIS software DEM data based on evaluation of landscape visual sensitivity analysis, level step by step evaluation of the subjective perception of the landscape transformed to objective data.Landscape visual quality assessment included evaluation of landscape resources and landscape visual quality assessment in the establishment of the sensitivity of the evaluation framework, the conclusion can be applied to various periods of landscape construction, the conclusion can be used for designers, policy makers and landscape managers; the public and experts as an evaluation body, plays a rigorous and objective experts and advantages of forward-looking, reflecting the importance of public preference for landscape.For evaluation practice Crater National Forest Park, the evaluation of the system landscape resources, landscape resources degree views, the visual quality of the landscape of the park and other indicators, the results of these evaluations will be calculated according to the park is divided into four visual quality of the landscape level, and for the proposed management objectives at each level and attractions, eventually combined with field survey questionnaire, proposed the development of strategies for the park as①add new media expand and diversify the tourist crowd;②improve landscape resources are better sex, tap human resources;③rich tourist route design, combining a variety of ways to explore;④improve the quality of service and attention to characteristics of the development;⑤into the ornamental increase participation in experiential activities;⑥understand the current situation, grading protection and orderly development.
