风景名胜区作为自然资源与人文资源交融的典型区域,面临着保护与利用的双重挑战。以江郎山国家级风景名胜区为研究对象,提出基于价值-风险的保护分区量化分析框架,以汇水单元为基础单元,综合考虑资源价值空间分析(资源级别优势度、资源聚集度、资源量值、资源丰富度、资源久远度、基于主要景观道路的可见性和价值潜在影响范围)与潜在生态风险评估(自然胁迫风险概率、人为胁迫风险概率、景观结构风险概率和自然恢复力),划分风景名胜区保护分区。结果表明:1)江郎山国家级风景名胜区的资源高价值区主要聚集在地质遗迹、人文遗址等区域;低价值区主要分布于资源要素匮乏或交通可达性较差的区域。2)高风险区与高人为胁迫、高景观结构风险区域高度重叠,低风险区则主要位于自然恢复力较强、人为开发强度较低的山林地带。3)江郎山国家级风景名胜区可划分出高资源价值-高潜在风险(Ⅰ)、高资源价值-低潜在风险(Ⅱ)、低资源价值-高潜在风险(Ⅲ)、低资源价值-低潜在风险(Ⅳ)4种区域类型。针对不同区域类型提出差异化的管控策略,为风景名胜区的科学管控与可持续利用提供了理论依据和实践指导。

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.
