The spatial–temporal distribution and evolution characteristics of carbon stock under the influence land use changes are crucial to scientific management environmental resources optimization spatial layout. Taking Xiamen–Zhangzhou–Quanzhou urban agglomeration in southeastern coastal region China as an example, based on seven types from 1990 2020, including cultivated land, woodland, construction we quantitatively investigate patterns development correlation distribution. Additionally, two scenarios for ecological priorities 2060 established effects stock. results indicate that (1) research area has formed a pattern centered around eastern bay area, with western forest belt serving barriers. Carbon is influenced by type, total exhibits aggregation phenomenon characterized “low southeast, high north, medium center”.

The degradation of Xing'an permafrost affects the stability carbon pool and emissions hemiboreal ecosystem in Northeast China. Due to lack long-term monitoring detailed research, changes stock terrestrial ecosystems regions China remain little known. In this study, we conducted more accurate simulations for aboveground biomass (AGB), belowground (BGB), dead organic (DOC), soil (SOC) top 0–30 cm using Integrated Valuation Ecosystem Services Tradeoffs (InVEST) model. model was applied multi-period land use/land cover (LULC) density data from late 1980s, 2000, 2010, 2020.

Habitat quality has great significance in terms of regional ecological conservation and human welfare. In this study, we evaluated the spatial temporal characteristics land use habitat temperate desert sub-region Ordos Plateau using patch-generating simulation (PLUS) integrated valuation ecosystem services trade-offs (InVEST) models. From 2000 to 2020, areas grassland, cropland, unused study area increased significantly; water bodies woodland slightly; wasteland decreased significantly. Moreover, subzone showed a trend initial increase then decrease between 2020. The lower low first increased, overall over time. Conversely, high higher initially decreased, medium although change was minimal. Based on PLUS model, predicted 2025 under natural development scenario compared that scenario. comparison results degradation These can be used provide scientific basis decision reference for sustainable resources encouragement high-quality socio-economic Plateau.

Using Changchun City as a case study and historical land-use data, simulated prediction of City’s structure 2035 change with GeoSOS-FLUS platform. We calculated storage volumes Low Impact Development (LID) designs using 2019 land surface data. The objective is 80% control rate by 2035. Through Monte Carlo simulation sensitivity analysis, assessed impact various types on LID calculations. Findings show that industrial significantly influences volumes. This highlights need precise surveys properties composition in planning more accurate analysis City. results indicate based current data may not meet long-term goals due to increased impervious surfaces coefficients during urbanization.
