基于评价型数字足迹的国家森林乡村景观多维感知研究——以安徽西递村为例

[Objective]China's national forest countryside is a type of countryside with important natural ecological resources and cultural landscapes,which plays a key role in ecological protection,tourism development and territorial planning.Currently,research on national forest villages focuses on the distribution pattern,spatial structure,and type characteristics at the macro level,but lacks the micro perspective to analyze and organize the landscape resources of the national forest villages and enhance the planning.Landscape perception theory explores the process and results of people's subjective analysis,perception and evaluation of various landscape environments through their senses under the background of social and individual heterogeneity,and ultimately plays a guiding role in landscape planning and design.With the advent of the Web 3.0 era,digital footprints have become a new type of landscape perception research by virtue of their advantages of type diversity,sample diversity,spatial and temporal extensibility,and data objectivity.Introducing landscape perception research based on digital footprints into national forest villages not only expands the research perspectives in related fields,but also helps to identify and solve the problems of national forest villages'landscape resources and promote the sustainable development of their landscape system planning.[Method]Xidi Village,located in Huangshan City,Anhui Province,is the second batch of national forest villages and an important regional green space.Evaluative digital footprints of recreationists on the landscape system of Xidi Village were collected through Python.Three rounds of preprocessing were performed to obtain a database of 1730 evaluative digital footprints with a total length of 82,870 words.The database was imported into ROST CM6 software,and semantic network analysis was used to sort out the general characteristics of recreationists'landscape perception of Xidi Village,and then a multidimensional landscape perception model was constructed based on it to analyze the details of recreationists'landscape perception of Xidi Village from four levels:natural ecological landscapes,historical and humanistic landscapes,landscape environmental atmosphere and emotional expression conditions.[Result]The results show that the recreationists'perception of the historical and humanistic landscape of Xidi Village is the strongest,accounting for 45.6％.The perception of landscape environmental atmosphere is in the middle,accounting for 29.9％.The perception of natural ecological landscape is weak,accounting for 23.5％.The majority of recreationists have positive feelings towards the landscape system of Xidi Village,accounting for 86.94％,while 6.24％and 6.82％of recreationists have neutral and negative feelings towards the landscape system of Xidi Village,and excessive commercialization and homogenization are the main factors triggering negative feelings.[Conclusion]According to the results of the study,four suggestions were made to optimize and manage the landscape system planning of Xidi Village:maintain and strengthen the existing advantages of the landscape system of Xidi Village,improve the protection and use of the natural ecological resources of Xidi Village,avoid excessive commercial development of the landscape system of Xidi Village,and establish a multi-dimensional feedback channel for recreationists.
