Simulating and predicting carbon storage under different development scenarios is crucial for formulating effective management strategies achieving neutrality goals. However, studies that focus on specific regions incorporate local policy context require further investigation. Taking Fujian Province as a case study, this research developed four policy-driven scenarios—natural development, farmland protection, urban ecological protection—based frameworks. Using the PLUS (Patch-generating Land Use Simulation) InVEST (Integrated Valuation of Ecosystem Services Tradeoffs) models, study simulated predicted dynamics each scenario. The results show declined from 1995 to 2020, mainly due conversion forests agricultural land into construction areas. protection scenario demonstrated highest potential recovery, projecting an increase 2.02 billion tons by 2030, driven afforestation conservation initiatives. Conversely, posed greatest risks, leading substantial losses. Key areas, including 12 priority districts, were identified in western northwestern regions, while coastal comprising 31 vulnerable face significant These findings emphasize need balanced use policies prioritize both achieve sustainable management.

Land use change plays a crucial role in global environmental change. Understanding the mode and land procedure is conducive to improving quality of eco-environment promoting harmonized development human–land relationships. Large river basins play an important areal socioeconomic development. The Yellow River Basin (YRB) ecological protective screen, economic zone, major grain producing area China, which faces challenges with respect degradation water sediment management. Simulating alterations ecosystem service value (ESV) owing YRB under multiple scenarios great importance guaranteeing security basin improve regional ESV. According data 1990, 2000, 2010, 2018, ESV over past 30 years were calculated analyzed on basis six types: cultivated land, forestland, grassland, area, built-up unused land. patch-generating simulation (PLUS) model was used simulate study three (natural development, protection, protection 2026); estimate each scenario; conduct comparative analysis. We found that changed significantly during period. has slowly increased by ~USD 15 billion years. obtained scenario highest. YRB’s future change, comparison analysis different scenarios, provide guidance scientific for conservation high-quality worldwide.

The Tarim River Basin (TRB) is situated in the hinterland of northwest China, which an extremely arid and fragile ecological zone. In recent years, region’s civilization construction has been facing huge challenges that are exacerbated by climate change human activities. order to verify current status TRB, this paper explores spatial temporal variation ecosystem service value (ESV) impact mechanism based on LUCC data from 2000 2020, using adjusted unit area equivalent method, elasticity index method geo-probe analysis method. results show that: (1) ESV TRB fluctuated since 2000, increasing CNY 14.02 billion, especially Hotan region. Among individual services, increase regulatory services largest, rising 8.842 billion. growth mostly occurred mountains oases. (2) rise mainly due conversion barren land water grassland; loss affected cropland grassland land. (3) Human activity or intensity (HAI) key driving factor for stratified heterogeneity ESV, followed elevation (DEM). interaction analysis, HAI∩DEM primary reason ESV’s differentiation. study’s findings combined effects activities, DEM, hydrothermal conditions underlie TRB. This conclusion provides a scientific basis future planning.
