Abstract:

【Objective】This study addresses the construction of scenic trails, aligning with the trend of resource integration in abundant region of nature reserves and the growth of global tourism. It begins with the recreational resources of abundant region of nature reserves and puts forward a comprehensive set of methods for selecting and planning recreational scenic trails from a regional perspective. This is intended to fill gaps in existing theoretical research on scenic trails at both the resource and regional levels within nature reserves. 【Method】Utilizing the analytic hierarchy process (AHP) and ArcGIS spatial analysis, potential scenic roads were preliminarily screened. Combined with the natural and human geographical characteristics of the study area, comprehensive evaluations of potential scenic roads were conducted. Key features of these roads were then summarized using visual field sections. 【Result】GIS spatial analysis yielded evaluations of each potential scenic road. After considering the current conditions and conducting overlay analysis, 23 potential scenic roads were identified. The comprehensive assessment of factors influencing route selection revealed 10 optimal scenic roads, including G205, G235, S222, among others. Furthermore, recreational scenic roads in southwestern Zhejiang were classified into three levels, with the distinct characteristics of each level described intuitively. 【Conclusion】The recreational scenic roads in the southwest of Zhejiang Province are meticulously planned according to a “2+6+7+N” construction pattern. This involves two national parks serving as core areas, six primary scenic roads functioning as communication corridors, and seven ecological recreation areas being interconnected in a series. Additionally, numerous branch corridors are prominently displayed. Concurrently, a visual area section analysis of these main recreational scenic roads has been designed, offering a theoretical foundation and data support for the scientific selection of scenic road routes in southwest Zhejiang.
