Studying the spatiotemporal distribution pattern of carbon storage, balancing land development and utilization with ecological protection, promoting urban low-carbon sustainable are important topics under China’s “dual strategy” (Carbon emissions stabilize harmonize natural absorption). However, existing research has paid little attention to impact use changes different spatial policies on provincial-scale ecosystem storage. In this study, we established a density database for Liaoning Province obtained temporal storage over past 20 years. Then, based 16 driving factors multiple in Province, predicted cover (LUCC) three scenarios 2050 analyzed characteristics response mechanisms scenarios. The results showed that (1) LUCC directly affected 35.61% increase construction decrease 0.51 Tg 20-year period. (2) From 2020 2050, varied significantly among trend scenario (NTS), restoration (ERS), economic priority (EPS), values 2112.05 Tg, 2164.40 2105.90 respectively. Carbon exhibited positive growth, mainly due substantial forest area. (3) was characterized by “low center, high east, balanced west”. Therefore, can consider rationally formulating strictly implementing policy protection future planning so as control disorderly growth land, realize area, effectively enhance ensure realization goal strategy”.

Changes in land use and cover (LULC) promote regional carbon storage capacity or trigger depletion, which turn exhibited significant impact on global climate change. Understanding the impacts of LULC changes coastal areas plays a critical role conservation ecosystems sustainable socio-economic development. The present study acted area Shandong Province as an example to analyze relationship between combined with Integrated Valuation Ecosystem Services Tradeoffs (InVEST) Patch-generating Land Use Simulation (PLUS) model. We further predicted variation through change types under three scenarios 2030. Our results showed that cropland (which decreased by 9.41%) built-up increased 7.66%) underwent most over past 20 years, while forest, grassland, wetland, water bare less changes. As dominant type, was also important pool medium storage. Areas high were distributed mountains hills, where main grassland forest. In addition, wetland located Yellow River Delta stores large amounts carbon. Accordingly, low widely urban metropolitan regions. pinpointed lost 47.96×106Mg due increasing decreasing ecological protection measures would effectively enhance Specifically, could be 6.64×106Mg when conversion cropland, forest into reduced 20% 30% (under priority scenario (EP)). believe valid reference for administrators develop policies more reasonable planning development achieve peaking neutrality ("Dual Carbon" goals).

Understanding the relationship between land-use patterns and regional carbon storage, as well predicting future changes for sink emission management, are of immense significance. This study utilized data from 1990, 2000, 2010, 2020, InVEST model, to evaluate spatiotemporal evolution storage in Sanjiangyuan area over past three decades. Furthermore, predictions 2035 were presented using PLUS model. The findings revealed following key results: (1) land types mainly low cover grassland, medium grassland unused land, among which decreased significantly 1990 wetland increased, is main reason increase storage. (2) Climatic-environmental social-economic factors jointly influenced change area. Except expansion other was by climatic environmental factors. (3) During 1990–2020, source region showed an overall upward trend, with a total 39.97 × 107 t, had positive potential impact on whole. (4) Under natural scenario, both density increased simulation 2035, positive. On this basis, paper puts some suggestions forward improve capacity future. provides valuable scientific insights management decision-making promotes sustainable development functions region.

The intensification of climate change and the implementation territorial spatial planning policies have jointly increased complexity future carbon storage changes. However, impact on under remains unclear. Therefore, this study aims to reveal potential impacts sequestration, providing decision support for addressing optimizing planning. We employed FLUS model, InVEST variance partitioning analysis (VPA) method simulate 15 different scenarios that combine Xiamen in 2035, quantify individual combined ecosystem sequestration. results showed (1) by Xiamen’s capacity is expected range from 32.66 × 106 Mg 33.00 various scenarios, reflecting a decrease 2020 levels; (2) conducive preserving storage, with urban development boundary proving be most effective; (3) greatly affected change, RCP 4.5 more effective than 8.5 maintaining higher levels storage; (4) influence sequestration consistently exceeds particularly high-emission where regulatory effect especially significant.
