| In the development and use of scenic spots,in order to ensure people’s demand for visual landscape and avoid damage and pollution to the visual landscape,it is often necessary to evaluate the visual landscape of scenic spots and make Suggestions for the planning and improvement of scenic spots.By collecting and sorting out the research results of theories and methods of visual landscape evaluation at home and abroad,this paper selects 26 main sightseeing routes and main scenic spots in Guanzhai Mountain scenic spot in the study area,and constructs a visual landscape evaluation model based on the characteristics of the research objects,which is mainly divided into three parts:Ⅰ.analyze the visual sensitivity of Guanzhai Mountain scenic spot by using GIS technology.Chances for relative slope,relative distance,visual and marked degree of four indicators,respectively map based on four indexes of visual sensitivity classification,according to the AHP analytic hierarchy process(AHP)to calculate the weight of each index,using the GIS spatial analysis tools,a weighted superposition after comprehensive visual sensitivity classification figure,and superimposed with various spots of viewing area,get the visual area of high,medium and low visualsensitive area distribution,including low sensitive area of 45.19%,in the sensitive area of 43.67%,high sensitive area covers an area of 11.14%.Ⅱ.Based on SD method,the subjective preference of 26 scenic spots in Guanzhai Mountain scenic spot was evaluated.Twenty pairs of adjectives with opposite meanings were selected to score the 26 main scenic spots of Guanzhai Mountain scenic spot by SD questionnaire.The scores of each evaluation factor and each scenic spot were obtained by sending questionnaires to professionals and processing data.Moreover,it is calculated that the average score of space element is 1.14,the average score of environment is 1.32,the average score of psychology is 1.05 and the lowest score of landscape is 0.79,indicating that the landscape of the scenic spot cannot meet the requirements of tourists.Scored an average of20 evaluation factor is higher than 0,the scenic spot of the overall evaluation is positive,one of the highest score for the landscape coordination degree(1.54),the lowest for the space open degree(0.68),color harmony,green coverage,security,easy degrees of factor score is higher,in the cultural atmosphere,and landscape richness and interesting and novel degrees lower scores,needs to be improved.Finally,a spline curve table is drawn according to the scores of each scenic spot,and the scenic spot is evaluated and analyzed one by one.Ⅲ.IPA analysis was used to construct the matrix of GIS visual sensitivity--SD subjective preference and draw scatter plots.GIS-SDvisual landscape matrix is established according to the IPA method,through to find center,set the X,Y,to build four quadrant,draw the various attractions in the distribution of the four quadrants,located in the first quadrant of the scenic spot is a Xiangnan cenotaph bamboo academy,the root of life,will reach pavilion,Guanglang valley,Triassic pool and Xianglanting wharf,these attractions are the best viewing area;Located in the second quadrant has the upstream first view,condense Bishan house,Yangyun pavilion,one line,Wulao peak,longevity pavilion service station,the above attractions should be mainly protected,natural development;The third quadrant scenic spots have scenic entrance,Fayunsi,Songfeng pavilion,Dongshancaotang,Lingzhi peak,the observation deck,these scenic spots have a certain amount of optimization space,but can be used as a secondary choice for improvement,slow progress;The fourth quadrant is the area to be improved urgently,which needs to be optimized and improved.There are beryl gorge,Banyun pavilion,Guzhaimen,Yanmen academy,carp back and Xianren valley.Finally combining the above evaluation results,the optimization of Guanhzhai Mountain scenic spot planning and scenic spot improvement Suggestions,mainly based on visual sensitivity to determine the area of development and protection,based on the SD method of subjective evaluation analysis of the advantages and disadvantages of variousattractions,according to the attractions of quadrant distribution in matrix to determine the optimal allocation of resources and priorities for improvement. |
