Study On Visual Landscape Quality Evaluation Of Wulong Suburban Forest Park In Dongshan,taiyuan

As an important part of urban green space system,suburban forest park not only realizes the function of ecological environment protection,but also provides an important activity place for people to get close to nature and have leisure and recreation.When people appreciate the landscape,they mainly acquire the information of the landscape through vision,thus producing the perception of the landscape.Visual landscape quality evaluation is an important index for tourists to make direct response to landscape and evaluate the beauty of landscape,which plays an important role in evaluating the landscape value of country forest parks.This paper takes Wulong suburban Forest Park in Dongshan,Taiyuan as the research object.Based on landscape perception theory,landscape aesthetics theory,Arnold’s emotion theory and other theories,through field investigation,and on the basis of constructing evaluation index system,this paper evaluates the visual landscape quality of the country forest park by combining scenic beauty evaluation method(SBE method)and semantic difference method(SD method).Then the visual landscape quality evaluation model was established to provide scientific reference for the construction and management of Wulong suburban forest Park in Taiyuan Dongshan City,so as to give full play to its landscaping and recreation functions.Specific research results are as follows:(1)The visual landscape quality of Wulong suburban Forest Park in Dongshan,Taiyuan was evaluated by SBE method.Firstly,a total of 16 inspection points on viewing platform and rest platform with a wide field of vision were selected as sample inspection points,and 48 landscape photos were selected as samples for landscape quality evaluation by taking photos and recording videos.Then 137 respondents were asked to judge,and 115 valid questionnaires were obtained.The data were standardized,and the samples were sorted and analyzed for landscape quality.The results show that:from the perspective of landscape elements,vegetation,artificial landscape architecture,color,shelter and other factors have a great impact on the visual landscape quality of Taiyuan Dongshan Wulong suburban forest park,among which people prefer the landscape with high vegetation coverage rate,rich landscape elements,bright colors and broad vision.(2)SD method was used to evaluate the visual landscape characteristics of Wulong suburban forest Park in Dongshan,Taiyuan.Based on the evaluation results of visual landscape quality obtained by SBE method,24 samples with the best landscape quality were selected as typical samples for analyzing landscape characteristics.By referring to relevant literature at home and abroad and combining with the landscape status of countryside forest parks,12 landscape characteristics were finally determined for evaluation,which are: landscape richness,color richness,vegetation diversity,vegetation significance,sense of space,sense of hierarchy,leisure,vitality,pleasure,sense of character,vernality,and sense of solitude.Then,30 environmental teachers and graduate students were invited as interviewees to evaluate the landscape characteristics.A total of 25 valid questionnaires were obtained,and the mean values of landscape characteristics were processed and analyzed.The results show that: from the perspective of the average landscape features,the highest scores are characteristic,quiet and leisure,while the lowest scores are landscape richness,color richness and vegetation diversity.These six landscape features play a key role in the attractiveness of park landscape.On the whole,the quiet sense,the sense of character and the leisure performance reflect the characteristics of the country forest park,which has special significance.It can provide leisure space for the public.However,there are some problems such as monotonous landscape,monotonous color and not rich vegetation species.(3)Combined with the evaluation results of beauty degree and landscape characteristics,the visual landscape quality evaluation model of Wulong suburban Forest Park in Dongshan City,Taiyuan was constructed through regression analysis,and the following results were obtained: Y(landscape beauty)=-0.261+0.028X1(landscape richness)+0.098X2(color richness)+0.045X4(vegetation significance)+0.018X6(layering)-0.079X8(vitality)+0.036X11(vernicity).It can be seen from the visual landscape quality evaluation model that the landscape characteristics affecting the landscape quality of Taiyuan Dongshan Wulong suburban forest park are listed in order of importance as follows: color richness > vitality > vegetation significance >vernality > landscape richness > hierarchy.(4)Based on the above visual landscape value evaluation research,the following problems exist in Wulong suburban forest Park in Dongshan City,Taiyuan: relatively monotonous color and weak visual impact;The plant species is not rich and the vegetation coverage rate is low.Landscape elements are not rich,and some landscapes are too simple.Therefore,the following optimization suggestions are put forward:enrich the diversity of landscape elements,improve the color richness of the landscape,adapt to local conditions,and adapt the land to the tree;Improve the level of park basic service facilities to meet the needs of tourists for leisure and recreation;Further strengthen landscape protection and construction work;Paving the internal roads of the country parks in a reasonable way to create unique features of the country parks;Strengthen the publicity of Wulong suburban Forest Park in Dongshan,Taiyuan,carry forward the history and culture,and enhance the cultural confidence of the
