Research On The Spatial Evolution Influencing Factors And Path Of The "Production-living-ecological" In The Longji Ethnic Villages In Guilin City

Under the background of “rural revitalization” strategy,the development of rapid urbanization has led to the decline or disappearance of the characteristics of some minority ethnic villages,so the protection of ethnic villages is particularly important.As minority ethnic villages in China,landscape villages in China,and traditional villages in China,the Longji ethnic villages are selected as a whole of the ecologically fragile,economically backward and special value.The terraced system has been selected into the global important agricultural cultural heritage protection list,so space evolution law study of Longji ethnic villages can provide useful reference and suggestions for the protection of ethnic villages and traditional villages,cultural inter-sex inheritance,tourism effect measurement and local spiritual remodeling in China.This paper chooses Pingan Zhuangzhai,Longji Gu Zhuangzhai and Jinkeng Dazhai,located in the Longji Terraced Field Scenic of Longsheng County,Guilin City as the research area,through remote sensing image interpretation and field investigation to obtain spatial data and field research data,using Participatory Rural Appraisal method and ArcGIS spatial analysis method to analyze the evolution path and its influencing factors of the “Production-Living-Ecological” space(living space,production space and ecological space)of Longji ethnic villages in 1990-2018 and explores the evolutionary driving mechanism.Research indicates:(1)During the period of 1990-2018,the living space of Longji ethnic villages experienced central gathering centered on the central village and spread to the periphery.The living space has undergone plane expansion and three-dimensional expansion.The function of the living space has changed from the traditional agricultural production and living function to the life function or tourism service production and life function.The structure of the living space has been transformed from the traditional wood structure to the reinforced concrete structure.The layout of the public living space has undergone linear-planar-mesh transition.(2)During the period of 1990-2018,the production space of Longji ethnic villages changed from traditional agricultural production to tourism service production.The overall agricultural production space has been reduced,and part of it has been transformed into ecological space and living space.With the maturity of hybrid rice technology,rice production has increased significantly.The service production space has gradually increased,and the environment and service quality of tourist reception facilities such as tourist restaurants and tourist homes have gradually improved.(3)Between 1990 and 2018,the ecological spatial layout of Longji ethnic villages experienced an overall expansion from the marginalization of the village edge to the interior of the village,and its expansion scope was mainly transformed from the agricultural production space.The internal ecological environment of the village has experienced the original ecological environment-the polluted ecological environment-the artificially improved ecological environment.The economic development and development of the Longji terraced scenic is the main reason for its change.(4)The spatial evolution of the “Production-Living-Ecological” in Longji ethnic villages is influenced by the combination of natural factors and humanistic social factors.Natural factors are the basic conditions for the evolution and development.The changes in farmers' needs and concepts,the spatial behavior of farmers and the traffic conditions at the location are the internal driving forces for the evolution.Tourism development,macroeconomic policies and social economy are the external driving forces for the evolution.(5)The healthy development of Longji ethnic villages requires unified planning,rational layout of living space,strengthening infrastructure construction,protecting traditional ethnic characteristics,strengthening ecological environment protection,and improving the overall appearance of the village.
