Preliminary Exploration of Literary Mapping Visualization of Xu Xiake's Travel Notes under Spatial Narrative:A Case Study based on Landscape Resources in Central Yunnan Region
With the advent of the digital age,the development of digital humanities holds enormous potential.It's crucial to present classical texts in a more accessible form to the public,not only aiding in their inheritance and promotion,but also in constructing modern cultural and tourism digital resources.Xu Xiake's Travel Notes is an extremely important historical prose travelogue.Based on landscape resources of central Yunnan region in the Travelogue of Central Yunnan,the locations in the book were sorted and integrated to determine their geographical positions.Through annotations in Google Earth Pro,a basic database of the scenic spots that Xi Xiake has visited in central Yunnan region was built.The locations are classified into twelve types,including administrative places,settlements,military places,transportation places,economic places,religious and sacrificial places,water bodies,mountains,scenic spot and historic sites,historical places,cave names as well as names of dams,gorges and docks.Simultaneously,the travel time of Xu Xiake at each location was standardized to create a timeline for temporal and spatial analysis later on.The journey of Central Yunnan Region was presented in three dimensions through literacy mapping and by integrating the spatial narrative theory with Time-Space-Temporary.Visual analysis of Xu Xiake's Travel Notes was conducted using kernel density estimation,co-occurrence analysis,time topology maps,GIS spatial analysis and space-time cube to determine the density of all scenic spots,segmented touring routes,types of itineraries as well as the specific cultural and natural landscape.The public can thus have personal experiences of the scenic resources recorded in Xu Xiake's Travel Notes,develop multi-dimensional thinking and cognition of single-dimensional text information and get a better understanding of overall travel routes of Xu Xiake,specific travel locations and cultural landscape.Research indicates that Kunming City has the highest visiting location density,followed by Qujing City,Chuxiong Yi Autonomous Prefecture,Honghe Hani and Yi Autonomous Prefecture and Yuxi City successively.Among all types of locations,the number of settlements is the highest,followed by mountains,water bodies and religious sacrificial places.The number of economic places is the lowest.According to distribution and density of locations,the Central Yunnan Region is surrounded by mountains,dispersed settlements and numerous branches of water systems.Considering the descriptions in the book,Yunnan was economically,politically,culturally and militarily underdeveloped due to its geographical location.Only the surrounding environment of Kunming City was good,while the rest areas were poor.However,people in most of the regions are welcoming.The construction of a basic database and a visual analysis of landscape resources in Central Yunnan Region recorded in Xu Xiake's Travel Notes are not only conducive to protecting the book in the modern digital age,but also effective ways for the public to deepen their understanding of Xu Xiake's culture.This study provides new ideas for subsequent construction of modern travel routes,cultural tourism zones and protection of Xu Xiake's cultural heritage.
