Abstract:

As a typical area where natural and human resources are intertwined,Scenic and Historic Areas are facing the dual challenges of protection and utilization.Currently,studies on the protection zoning of the Jianglangshan Scenic and Historic Areas were focused on a single dimension and lacked the comprehensive consideration of resource value and ecological risk.Taking Jianglangshan Scenic and Historic Area as the research object,we proposed a quantitative analysis framework for conservation zoning based on the two-dimensional perspective of “value-risk”,with the catchment unit as the research base unit.Considering the comprehensive analysis of resource value space(Resource Level Advantage Degree,Resource Aggregation Degree,Resource Value,Resource Richness,Resource Longevity Degree,Visibility,Value Potential Impact Range)and potential ecological risk assessment(Natural Stress Risk Probability,Human-Induced Stress Risk Probability,Landscape Structure Risk Probability,and Natural Resilience),the protection zones were delineated for Scenic and Historic Areas.The results indicate that the high-value resource areas of Jianglangshan Scenic and Historic Area are mainly formed by the aggregation of geological relics,cultural sites,and other factors;the low-value areas are primarily distributed in regions with scarce resource elements or poor transportation accessibility.The high-risk areas significantly overlap with areas of high human-induced pressure and high landscape structure risk,while the low-risk areas are mainly located in forested regions with strong natural resilience and lower levels of human development.Accordingly,four types of zones,namely,High resource value-High potential risk(Ⅰ),High resource value-Low potential risk(Ⅱ),Low resource value-High potential risk(Ⅲ),and Low resource value-Low potential risk(Ⅳ),were classified.Differentiated control strategies are proposed for different types of areas,providing theoretical basis and practical guidance for scientific management and sustainable utilization of Scenic and Historic Areas.
