Comparative Study On Visual Landscape Quality Of The Ancient Town Of Salt Road In Sichuan

With the strategy of coordinated regional development put forward by 19 th CPC National Congress of the Party,it has provided a good opportunity for the revival of the Sichuan Salt Path,and the ancient town of Yandao has also appeared in people’s vision.The strong cultural atmosphere of Yandao ancient town,coupled with beautiful natural landscape,magnificent human landscape and other unique landscape resources have brought people visual experience and spiritual enjoyment,as well as promoted the development of tourism in Yandao ancient town.But due to the desolation of the ancient Sichuan Salt Path and the rapid development of the modern town,the historical and cultural elements of the landscape of the ancient town have been gradually weakened,the traditional historical landscape is seriously damaged,and the new and the old landscape could not blends.Therefore,the protection and planning of Sichuan Salt Path landscape is extremely urgent.This paper has used a variety of visual landscape evaluation methods to evaluate the landscape of Yandao ancient town,using four typical ancient towns on the eastern commercial path Luoquan,Luocheng,Xianshi,Niufo as the research objects.First of all,four ancient towns of Yandao have been investigated on the spot,and their landscape status was sampled and recorded.Secondly,according to the present situation of natural landscape and human landscape,the landscape of the ancient town of Yandao is divided into nine categories: topographic landscape,plant landscape,water landscape,wharf landscape,residential landscape,historical and cultural architecture landscape,street and lane landscape,sketch landscape,square landscape,etc.And in these nine major types of landscape,a number of landscape nodes have been selected as the landscape evaluation samples,each ancient town with 9 landscape sample.The beauty degree evaluation method of SBE method has been used to evaluate the landscape quality of the samples.At the same time,the semantic difference method and SD method are used to evaluate and analyze the landscape characteristics of the landscape nodes and the results are obtained.Finally,theregression analysis is used to establish the evaluation equation of the landscape quality of Yandao ancient town.Then,the landscape evaluation results of the four ancient towns are compared and analyzed,and the similarities and difference of landscape quality and characteristics of the ancient towns has been discussed.Through the evaluation results of landscape quality of Yandao ancient town in Sichuan,the following conclusions can be drawn: From the viewpoint of salt landscape quality,the overall evaluation of the landscape quality of Yandao Ancient Town is relatively low,and the degree of damage to the landscape of Yandao Ancient Town is relatively large,and the protection of the landscape is insufficient.Comparing the quality of the visual landscape of the four Yandao ancient towns,the quality of the visual landscape of the ancient town of Xian City is obviously better than that of other ancient towns.The evaluation of the ancient town of Niufufo is the lowest,and the order of the landscape quality is Xianshi Ancient Town,Luocheng Ancient Town,and Luoquan Ancient Town.,Niufu Ancient Town;Comparing the evaluation results of Yandao ancient town landscape,historical and cultural architectural landscapes,plant landscapes,water landscapes,and residential landscapes are better in the quality evaluation of the visual landscape of Yandao Ancient Town,while the pier landscape and square landscape are in the ancient town of Yandao.The visual landscape quality is lower.Judging from the landscape features of the salt road,spatial features such as sense of hierarchy,beauty,color richness,atmosphere,and sense of vitality play an important role in the evaluation of ancient town landscapes.Spatial continuity,hue,complexity of elements,and sense of form,Destructiveness,etc.Evaluation is not good.By selecting the most prominent landscape features that are positively related to the landscape quality and the most obvious landscape features negatively related to the landscape quality,the landscape samples of the four salt road towns corresponding to the landscape features are compared to explore the constituent elements of the landscape samples.Historical and cultural architectural landscapes and residential landscapes have the most significant characteristics of landscape aesthetics,richness of colors,sense of form,and complexities of features;residentiallandscapes have the best visual effects of form perception;natural landscapes have a distinct sense of spatial layering;residential landscapes are The sense of form has the best visual effect;the landscape of the pier has outstanding features such as the richness of color,the complexity of features,and the destruction of landscape features,and the destructiveness of the square landscape.Therefore,this paper combines the characteristics of Yandao Ancient Town and explores a series of strategies for the protection and promotion of the landscape of salt roads.
