Research On Landscape Visual Evaluation Of Urban Mountain Park Based On GIS

Comparing with general urban park or forest park,urban mountain park has a great particularity,it has native mountain vegetation types,and the public space to create an artificial.Compared with urban parks under artificial intervention,it owns unique spatial distribution,ecological composition,landscape composition and climate environment.Therefore,the landscape planning and design of urban mountain park requires not only considering the particularity of its own,but also establishing the Multi layer spatial model to meet people’s visual aesthetic experience and achieving effective balance between ecological protection and resource utilization.According to the particularity of the City mountain park landscape composition,landscape in the traditional visual evaluation method(landscape visual sensitivity evaluation,landscape evaluation)on the basis of referring to the theory of landscape ecology,landscape ecological evaluation of vision is proposed based on the sense of vision,namely ecological evaluation,using the edge contrast index of landscape pattern index in as a visual ecological evaluation standard,and according to the three evaluation system of comprehensive evaluation of the City mountain park landscape vision method is determined,the establishment of evaluation framework.Using AHP analysis method,SBE method,GIS evaluation method for their evaluation,establish relevant evaluation index weights,respectively,from the subjective level,the landscape ecological level,landscape level three aspects by way of quantitative data weighted overlay analysis,comprehensive evaluation of construction of the City mountain park landscape vision the frame.Containing the scenic landscape evaluation,landscape visual sensitivity and visual evaluation of ecological evaluation framework,and the evaluation results can be used to guide the development and protection of the City mountain park landscape,it can provide a reference for designers,managers in planning and management process;therefore,it has theoretical value and practical significance to explore the quantitative technology of urban mountain park visual landscape evaluation based on GIS technology and landscape ecology.Based on the evaluation practice of the mountain city mountain park,the park system evaluation of scenic landscape,landscape visual sensitivity and visual quality of park landscape ecological index,according to the comprehensive quality of the landscape is divided into four grades,and put forward the protection target and development strategy.
