“…This result aligns with the view that forest ecosystems have a high carbon sequestration capacity 46 . Interestingly, our results show that the carbon storage in NC is projected to decline only under the high carbon emission scenario of SSP5–8.5 by 2030ss, which is contrary to the previous studies that China’s carbon storage faces a risk of decline in 2030 47 . This discrepancy may be due to the fact that NC is the largest concentrated distribution area of natural forests in China, serving as a crucial ecological barrier for China and even Northeast Asia.…”

Climate change and land use change caused by human activities have a profound impact on ecological security. Simulating the spatio-temporal changes in ecosystem service value and ecological security patterns under different carbon emission scenarios in the future is of great significance for formulating sustainable development policies. This study quantified the four major ecosystem services (habitat quality, water retention, soil erosion, and carbon storage) in Northeast China (NC), identified ecological source areas, and constructed a stable ecological security pattern. The results show that the spatial patterns of soil erosion, carbon storage, water retention, and habitat quality, the four major ecosystem services in NC, are relatively stable in the next 30 years, and there is no significant difference from the current spatial pattern distribution. The SSP1–2.6 carbon emission scenario is a priority model for the development of NC in the next 30 years. In this carbon emission scenario, the NC has the largest ecological resources (191,177 km2) and the least comprehensive resistance value (850.006 × 10−4). At the same time, the relative resistance of the corridor in this scenario is the smallest, and the area of the mandatory reserve pinch points is the least. The ecological corridors in the SSP1–2.6 scenario form a network distribution among the ecological sources, connecting several large ecological sources as a whole. This study fills the knowledge gap in building a stable ecological security pattern in NC under the background of global change, and provides a scientific basis for the decision-making of regional ecological security and land resource management.

“…Expanding cropland often results in forest clearance, diminishing carbon storage due to cropland's typically lower organic matter content. Conversely, increased forest coverage augments carbon sinks, with vegetation adeptly transforming carbon to organic matter via photosynthesis(Zhang et al 2023). Urbanrural construction land proportions correlate with residential energy consumption and building carbon footprints(Li et al 2022), while industrial, mining, and transportation lands, as primary functional construction lands, significantly influence industrial and transportation carbon emissions(Kang et al 2023).Scale efficiency relates to population, economic, and environmental shifts across land uses(Liu et al 2021).…”

The attainment of a regionally balanced carbon budget is fundamental for the realization of carbon neutrality. This study involved the quantification of the carbon budget related to land use across Southeast China from 2005 to 2020, which was achieved through the calculation of both carbon emissions and carbon sinks. Subsequently, we scrutinized the mechanisms driving the observed dynamic changes in the carbon budget, pinpointed the impact of land-use efficiency (LUE) on the carbon budget, and proposed sustainable spatial planning and management strategies for diverse functional areas at the county level. The core findings are as follows: The dynamics of the carbon budget were spatially heterogeneous, characterized by a gradual increase in carbon emissions over time, while carbon sinks remained relatively constant. The Gini coefficient (G) manifested a gradual increase throughout the study period, reflecting an imbalanced evolution between carbon sinks and emissions. There was also an observable imbalance in the distribution of the carbon ecological carrying coefficient between coastal and inland regions. Land-use-related carbon emissions demonstrated a substantial spatial spillover effect, whereas a weak spatial spillover effect was noted in land-use-related carbon sinks. The correlation between LUE and the carbon budget varied significantly across different functional areas, as the driving effects of LUE displayed remarkable spatial heterogeneity. A quantification of the spatio-temporal alterations and the driving mechanisms behind the carbon budget can aid in the advancement of urban sustainability and regional carbon neutrality.

“…The inclusion of ecological quality elements into ESV can provide relevant insights for identifying ES spatio-temporal dynamic changes [29]. Carbon sequestration maintains healthy ecosystems and serves many benefits for human beings [30,31]. Meanwhile, ES also may provide nonmaterial contributions through recreation and aesthetic experiences but faces exceptional challenges to be integrated concretely and comprehensively into ES identification [32].…”

As a crucial component of the ecological security pattern, ecological source (ES) plays a vital role in providing ecosystem service value (ESV) and conserving biodiversity. Previous studies have mostly considered ES only from either landscape change pattern or ecological function perspectives, and have ignored their integration and spatio-temporal evolutionary modeling. In this study, we proposed a multi-perspective framework for the spatio-temporal characteristics of ES by ESV incorporating landscape aesthetics, carbon sink characteristics, ecological quality, and kernel NDVI (kNDVI). By integrating the revised ESV and the kernel normalized difference vegetation index as a foundation, we employed the spatial priority model to identify ES. This improvement aims to yield a more practical and specific ESV result. Applying this framework to the Three-River Headwaters Region (TRHR), a significant spatio-temporal change in ecological sources has been observed from 2000 to 2020. This performance provided a reference for ecological conservation in the TRHR. The results indicate that this ecological source identification framework has reliable accuracy and efficiency compared with the existing NRs in the TRHR. This method could reveal more precise spatio-temporal distributions of ES, enhancing ecosystem integrity and providing technical modeling support for developing cross-scale spatial planning and management strategies for nature reserve boundaries. The framework proposed in our research could serve as a reference for building ecological networks in other ecologically fragile areas.
