自然保护地整合优化有新要求，相关规则进一步明确

Core Viewpoint - The ongoing optimization and integration of natural protected areas in China is being refined, with provincial-level results being developed and approved in batches, following the release of the "National Natural Protected Area Integration and Optimization Plan" by the National Forestry and Grassland Administration and the Ministry of Natural Resources [1][2]. Group 1: National Policy and Implementation - The National Forestry and Grassland Administration and the Ministry of Natural Resources have issued a directive to enhance the integration and optimization of existing natural protected areas, ensuring that the process is rigorous, data-driven, and responsive to public concerns [2]. - The integration plan is still pending approval and cannot be considered effective until then, although provincial departments are encouraged to begin preliminary work on key projects [1][2]. Group 2: Provincial Actions and Results - Various provincial authorities, including those in Shandong and Zhejiang, have publicly announced their local integration and optimization plans, resulting in a reduction of protected areas and an increase in total area [2]. - In Zhejiang, the number of natural protected areas decreased by 78 to a total of 166, while the total area increased by approximately 120 square kilometers to 14,693 square kilometers [2]. Group 3: Guidelines for Optimization - The "Natural Protected Area Integration and Optimization Rules" stipulate that smaller, fragmented, or less ecologically valuable protected areas may be revoked or reclassified, while areas with significant ecological or cultural value must be preserved [5][6]. - The integration process will consider factors such as ecological systems, resource ownership, and management structures, with a preference for merging lower-tier protected areas into higher-tier ones [5][6].
