Study On Landscape Evaluation And Optimization Strategy Of Ethnic Villages In Western Sichuan Alpine-gorge Region

Western Sichuan alpine-gorge region refers to the transition area where the middle Sichuan Basin meets the Qinghai-Tibet Plateau and the altitude gradually rises in western Sichuan.The Zheduo mountains in the northwest to southeast direction are taken as the dividing line.The western Sichuan alpine-gorge region includes the northeastern margin of Ganzi Tibetan Autonomous Prefecture and the southeastern part of Aba Tibetan and Qiang Autonomous Prefecture.As the cultural convergence zone of Tibetan,Qiang,Han and other ethnic groups,it can be reflected in the concrete situation of human settlement environment and natural ecological environment in the western Sichuan alpine-gorge region under the background of ethnic integration.However,under the impact of the Wenchuan earthquake restoration and urbanization,the settlements should not only preserve their ecological advantages and traditional culture,but also develop tourism to drive the economy.The landscape of ethnic settlements in the western Sichuan alpine-gorge region is facing severe challenges.This article western Sichuan alpine-gorge region within the scope of the ethnic villages of settlement landscape as the research object,western Sichuan alpine-gorge region ethnic village settlement landscape overall investigation,the investigation after the actual experience of residents and visitors of settlement landscape,evaluate the settlement landscape and optimization strategy is put forward,finally an empirical study in Zhonglu village.First of all,consult the literature and collate the relevant research results at home and abroad.Combined with the literature and materials consulted,the ethnic settlements in western Sichuan alpine-gorge region were investigated and designed,and the selected sites and specific investigation contents and elements were prepared.Research process development includes two parts,namely the western Sichuan mountain canyon national settlement landscape to two kinds of the natural landscape and human landscape,cultural landscape under the cultural landscape is divided into material and nonmaterial cultural landscape,carding western Sichuan mountain canyon national settlement landscape,choose seven key tourist construction and protection of ethnic village to carry out the investigation and research,The research results serve as the basis for qualitative research.In the quantitative research part,the analytic hierarchy process(AHP)was used to construct a comprehensive evaluation system for the landscape of ethnic settlements in western Sichuan alpine-gorge region,and 21 evaluation elements were established.After determining the weight of each factor,questionnaires were issued and collected for all the surveyed settlements,and the target population of the questionnaires were permanent residents and tourists.After the survey,the evaluation results of each settlement landscape were summarized.Combined with field research,this paper summarizes the common problems faced by the landscape of ethnic villages in western Sichuan alpine-gorge region.Combining qualitative research and the evaluation results,grab the characteristic of western Sichuan alpine-gorge region and the settlement landscape development rule,establish the optimization strategy is put forward the principle,combined with the comprehensive evaluation results of sample settlements bias and its different development,puts forward the ecological maintenance,leading industry and protect the development of three types of settlement landscape optimization model.With the landscape architecture,landscape ecology and urban and rural planning and other related multidisciplinary theory,put forward the optimization strategy,the natural landscape of hills,vegetation,etc by means of repair,settlement external drainage rivers give priority to in order to maintain water and soil,the construction of residents recreation space is complementary,internal water network space to enhance tourist experience and practical give priority to.In the cultural landscape,it is necessary to optimize the layout of settlements,fully coordinate the features of old and new buildings,optimize the space of streets and lanes,and combine the development of agriculture and tourism.In addition,the continuation of religious culture and folk culture needs to integrate local forces and cooperate with residents and tourists to participate in enhancing the sense of experience.Therefore,it provides a basis for the future optimization and development of ethnic village landscape in western Sichuan alpine-gorge region.Finally,taking Zhonglu Village as an example,the empirical study is carried out,and the optimization strategy is applied in practice to explore the protective development of settlement landscape.
