Abstract The regional terrestrial ecosystems serve as primary carbon sinks, characterized by strong spatial heterogeneity and significant interannual fluctuations. In Xinjiang, one of China's five autonomous regions, storage increased from 12,967.89 TG to 14,262.31 TG. Traditional sink assessment methods struggle fully account for the combined impacts human activities environmental factors, impeding accurate depiction distribution evolution stocks. This study proposes a ecosystem density estimation method based on an ARIMA-CatBoost-RNN coupled model. Firstly, ARIMA model forecasts time series, CatBoost reduces heterogeneity, RNN estimates values. Secondly, is estimated using improved InVEST model, with accuracy up 78.4%. Finally, Geodetector quantifies influence nine driving factors capacity. results reveal that soil stocks comprise 55%-61% total storage, making them main component Xinjiang's ecosystems. Annual average sequestration 39.02 T/km², forests showing highest capacity at 103.33 T/km². NDVI(Normalized Difference Vegetation Index) has most impact capacity, contributing 0.615.

The demands on our landscapes increasingly conflict with each other (e.g., the transition to sustainable agriculture versus expansion of urban areas). We must address increasing land degradation problems erosion, loss soil fertility and biodiversity, floods, pollution) imperative move toward use sustainability. Making decisions meet these diverse requirements solve is often highly complex challenging. Similar issues are evident in implementation multiscale policies at global SDGs), European CAP), national climate change adaptation plans EU Member States), regional Nitrates Directive), local planning) levels. There a need bridge knowledge gap between decision-makers, who require operational support implement actions sustainability, research community. development Decision Support Systems (DSS), particularly geoSpatial (S-DSS) including Digital Twin-based tools, offers promising avenue challenges. Over past decade, advancements S-DSS were driven by progress management sciences, databases, modelling, datacube technologies, high-performance computing (HPC), Earth Observation (EO), artificial intelligence (AI), WebGIS facilities, Geospatial Cyberinfrastructure. Together, have significantly enhanced connection resource science practical, management. In this scenario, current LDD special issue collects papers advanced approaches methodologies land-based Spatial (S-DSS), aiming whether can effectively handle complexity challenges mentioned above facilitate use. focus cover following items: (i) diversity approaches, both from methodological end-user perspective, using multidisciplinary multifunctional strategies view Systems, (ii) promote uses various sectors such as agriculture, forestry, planning, revitalization, change, environmental human health.

Estimations of the patterns and controls soil organic carbon (SOC) could provide instructive insights into potential impact future global change on (C). In this work, we combined GeoDetector random forest (RF) to estimate SOC stocks in Chinese grassland ecosystems with uncertainty assessments, identified a network cross-correlated environmental covariates for determining based dataset collected from 813 sampling sites (0–20 cm) 2000 2014. We predicted that 17.50 Pg C was stored grasslands depth 20 cm average density 4.69 kg C/m−2(−|−). The effectiveness using RF predict demonstrated by an accuracy assessment 10-fold cross-validation, ratio performance deviation (RPD) 2.89. southern China were lower than those northern China. A high found northeastern Qinghai–Tibet Plateau. Soil properties had strongest direct effect SOC. Climate significantly negatively associated indirectly affected via its properties. Topography significant vegetation, but relatively weak. This study emphasizes heterogeneity as well relative significance climate, characteristics, topography, their complex interrelationships controlling These results may theoretical foundation developing sustainable management systems calibrating process models.
