Abstract: With the release of the National Park Spatial Distribution Program, China is accelerating the construction of the world′s largest national park system. However, natural recreational activities still face numerous challenges, including an imbalance between conservation and development, rudimentary zoning management, and a lack of comprehensive guidelines for facility construction. For instance, the existing binary division of "core protection area-general control area" fails to accommodate diverse recreational needs. The general control area, which constitutes over 40% of national parks, varies significantly in terms of protection intensity and activity demands but is subject to uniform management. Additionally, the absence of standardized facility construction guidelines has sparked controversy. To address these issues, this study systematically analyzes the limitations and complexities of the current zoning system and proposes a localized "four-tier zoning" technical framework, drawing on the internationally recognized Recreational Opportunity Spectrum (ROS) theory. Specifically, no recreational facilities area permits only patrol infrastructure; simple recreational facilities area allows unpaved trails but prohibits motorized facilities; basic recreational facilities area supports low-intensity motorized facilities; complete recreational facilities area accommodates high-intensity use, subject to environmental impact assessment. This framework centers on facility construction intensity (such as road paving, motorized facilities, scale) as a core zoning criterion, achieving three key breakthroughs: 1) Resolving zoning compatibility challenges: By simplifying the six-tier ROS into a four-tier model better suited to China′s conditions, it supports the "differentiated utilization control" requirement in the proposed National Park Law. 2) Clarifying facility construction standards: It provides precise management tools for 11.61% of the candidate areas for national parks, resolving disputes over "what to build and where to build". 3) Demonstrating feasibility through case studies: Application in Wuyishan National Park reduces disputes regarding facility construction and promotes local community income. In conjunction with this zoning system, the following improvements are suggested: 1) Further revision of the "Technical Specifications for National Park Master Planning" to include specialized chapters on zoning and facility standards; 2) Development of "National Park Recreational Facility Construction Standards", quantifying intensity indicators such as paving rate, density, floor area ratio, and visitor density; 3) Promotion of a "zoning intelligent control system" to monitor non-compliant facilities; 4) Establishment of a "recreational carrying capacity quantification model", setting visitor limits for each zone. Ultimately, this study aims to maximize visitor satisfaction while minimizing environmental impact, surpassing traditional binary zoning models. The framework integrates policy requirements, practical needs, and advanced concepts, providing a precise management tool for China′s national parks. Its implementation will support the National Park Law and the National Park Spatial Layout Plan, fostering a sustainable balance between conservation and development while offering actionable guidelines.
