The advancement of the big data industry is playing a pivotal role in urban land management refinement. Recently, China initiated strategy, establishing national comprehensive pilot zones (NBDCPZs) across diverse regions. These initiatives present substantial opportunities for enhancing green use efficiency (ULGUE). Consequently, this study, we utilized super-efficiency slack-based measure (SBM) model with undesirable outputs to assess ULGUEs 281 prefecture-level cities from 2006 2021. Subsequently, leveraging NBDCPZ establishment as quasi-natural experiment, employed difference-in-differences (DID) method empirically explore impact policy on ULGUE first time. findings revealed following: (1) implementation significantly enhances ULGUE; (2) effects are mediated through mechanisms such fostering technological innovation, mitigating resource misallocation, and promoting industrial agglomeration; (3) heterogeneity analysis emphasizes increased effectiveness characterized by fewer natural resources, lower economic growth pressures, stable development stages, moderate digital infrastructure human capital levels; (4) further demonstrates significant positive spillover neighboring non-pilot cities, diminishing proximity between decreases. Overall, study contributes literature relationship economy utilization, offering valuable insights achieving sustainable development.

The low-carbon utilization (LCU) of territorial space represents a critical strategy for addressing climate change and promoting sustainable development, yet current assessments in this domain remain insufficient. This study develops an integrated assessment framework utilizing kernel density estimation, optimal parameter-based geographical detector, the Tobit regression model to analyze spatiotemporal evolution, typology, driving factors LCU Yangtze River Economic Belt. findings reveal that index region increased from 0.548 2005 0.569 2020, despite significant regional disparities. Cities are classified into eight distinct types LCU, with over 80% demonstrating poor performance at least one functional space, particularly urban where number cities below average is highest. analysis demonstrates spaces influenced by integration natural conditions, socio-economic factors, landscape patterns. In light these findings, systematically proposes policy recommendations enhance space. research contributes establishment scientific evaluation providing empirical evidence improve spatial governance policies support development.

Enhancing carbon storage in terrestrial ecosystems has become a key strategy for mitigating climate change. The Tibetan Plateau holds pivotal position achieving neutrality, with the structural pattern of its land use types directly impacting region’s ecosystem capacity. However, there is still lack understanding spatial distribution their ecosystems. This study targeted Plateau, utilizing data from 2000 to 2020, and employed Patch-generating Land Use Simulation (PLUS) model project patterns 2030. By integrating future change projections, this forecasted under SSP1-2.6, SSP2-4.5, SSP5-8.5 scenarios. Integrated Valuation Ecosystem Services Tradeoffs (InVEST) was quantify 2030, while GeoDetector used explore driving influences factors such as Normalized Difference Vegetation Index (NDVI), Water (NDWI), Leaf Area (LAI), Net Primary Productivity (NPP), population density, road network density on storage. results revealed that: (1) Grassland predominated most having stability over 70%, whereas significant changes were observed western Tibet Autonomous Region southern Xinjiang Uygur Region. (2) Carbon generally followed tendency towards an initial decrease by increase, average annual reduction 50,107,371.79 Mg. SSP1-2.6 scenario demonstrated substantial increase storage, being 18 times natural trend, indicated largest decrease. (3) Over two decades, NDVI emerged influential driver which maintained at around 0.4, interaction between NDWI exerting strongest force, 0.45. conversion forestland grassland primary factor accounting Based these results, despite absence empirical data, could be regarded reference pathway Plateau.

Under the background of rapid urbanization, strengthening research on response and dynamic mechanism ecosystem services to land use is conducive optimization space ecological restoration governance in megacities. Using Hefei City as a case study, we examined specific analyzed how water yield, habitat quality, carbon storage, soil conservation changed over time from 2000 2020. We utilized spatial information technology InVEST model assess these changes. Additionally, developed comprehensive service index (CES) used Geodetector regression models investigate responded use. In addition, Patch-generating Land Use Simulation Model (PLUS) simulate distribution 2030.
