蓝皮书：生态系统质量呈持续改善局面

Core Viewpoint - The "Blue Book" indicates a continuous improvement in the quality of ecosystems within the ecological protection red lines in China, highlighting significant advancements in management capabilities and ecological conditions [1][2]. Group 1: Ecosystem Quality Improvement - The average vegetation coverage within the red lines has increased by 1.29%, and the net primary productivity has improved by 2.22% [2]. - Forest coverage and forest stock have both seen growth, while the overall condition of grassland vegetation is stable and wetlands' water source security is generally good [2]. - Marine water quality remains stable, with notable improvements in typical ecosystems such as mangroves (area increased by 22%), coral reefs (average live coral coverage increased by 5.5%), and seagrass beds (average coverage increased by 9.4%) [2]. Group 2: Management Capability Enhancements - A preliminary control mechanism has been established that promotes central-local collaboration, departmental coordination, and a combination of rigid and flexible management, significantly enhancing management efficiency [2]. - An integrated monitoring network ("air-space-ground") has been gradually developed, improving the dynamic and precise perception of the red lines [2]. - Active exploration and practice in ecological protection and restoration, realization of ecological product value, boundary demarcation, and public awareness have led to the formation of replicable and promotable advanced experiences [2].
