Assessing Forest Carbon Sequestration in China Under Multiple Climate Change Mitigation Scenarios

Land, Journal Year: 2025, Volume and Issue: 14(3), P. 571 - 571

Understanding how climate policies impact forest carbon sequestration is crucial for optimizing mitigation strategies. This study evaluated in China from 2020 to 2060 under three scenarios: SSP1-2.6 (high mitigation), SSP3-7.0 (limited and SSP5-8.5 (no mitigation). We integrated the land-use harmonization (LUH2) patch-generating simulation (PLUS) models project cover change, Lund–Potsdam–Jena managed land (LPJmL) model simulate dynamics. The results showed stronger efforts led higher sequestration, with annual rates of 0.49, 0.48, 0.20 Pg yr−1 across scenarios. achieved highest density (17.75 kg m−2) (56.95 Pg), driven by greatest increases existing forests (+41.56%) soil (+39.94%). SSP3-7.0, despite (34.74%), had a lower (17.19 (56.84 Pg). recorded lowest (27.12%) (45.62 Increasing density, rather than expanding area, could be more effective China. were 2.36 2.89 times new forests. recommend prioritizing maximize focusing on protecting southwest carbon.

Research on the Driving Factors and Trade-Offs/Synergies of Woodland Ecosystem Services in Zhangjiajie City, China

Sustainability, Journal Year: 2025, Volume and Issue: 17(9), P. 3916 - 3916

Published: April 26, 2025

Research on woodland ecosystem services is the premise of formulation regional policies and ecological protection measures in a new round utilization planning. Based remote-sensing images socioeconomic data, this study used InVEST model, geographical detectors, Spearman correlation analysis, coupling coordination degree model to evaluate spatiotemporal changes, driving factors, trade-off/synergies relationship habitat quality (HQ), soil conservation (SC), water (WC), carbon storage (CS) Zhangjiajie City 1995, 2005, 2015, 2022. The results show following: (1) HQ significantly decreased, SC WC fluctuated CS continued increase. (2) Natural factors were predominant, other natural interact increase effect. (3) four dominated by weak synergy, but turned into trade-offs These research can provide theoretical support for optimization tourism development compensation policies, high-quality sustainable City, case management world heritage sites.
