The establishment of the ecological protection redline (EPR) in China plays a crucial role safeguarding key functional areas and sustaining biodiversity. Besides their significance, impact these redlines on regional carbon sequestration remains unclear due to current inconsistencies implementation adjustment. This paper conducts thorough analysis evolution two EPR versions Hainan Island employs InVEST model assess effects storage between 2000 2020. Additionally, spatial autoregressive is integrated explore socioeconomic environmental driving mechanisms behind changes storage, thereby revealing complex interactions policy adjustments ecosystem services storage. Key findings include: (1) 2022 area has improved management boundaries, permanent cultivated land, urban development outperforming 2016 version, particularly control construction land water resource management. (2) EPR2022 exhibits higher per area, indicating more effective zoning system. increase primarily observed transitions from forest, grassland bodies grassland. (3) Elevation relatively strong positive correlation with within EPRs, high-altitude typically encompassing core zones tropical rainforest national parks that possess diverse vegetation stable ecosystems, conducive maintaining or increasing Evaluating efficacy enhancing critical for refining strategies achieving neutrality goals.

Abstract. Environmental assets provide important benefits to society and support the equilibrium of natural processes. They can be affected by floods; however, flood risk analyses usually neglect environmental areas due (i) a lack agreement on what should considered an asset, (ii) poor understanding values, (iii) absence damage models. The aim this work is advance exposure river floods first identifying asset typologies that could in second introducing method, named EnvXflood, estimate qualitative values assets. method structured around three levels detail requiring increasing information, from fast minimal-resource analysis suitable for regional assessment detailed ecosystem-service-based site analysis. Exposure focuses social value Social were investigated means participatory approach. was tested case studies Italy (the Tuscany region, Chiana Basin, Orcia Basin). ecosystem service weighting obtained approach highlights perceived leading importance biodiversity-supporting service. results show related water, such as rivers, lakes, wetlands, are most exposed floods. However, they commonly not typical management practices. Further research at consolidating included their ecological value, moving towards coherent impacts.
