Land use, as one of the major sources carbon emissions, has profound implications for global climate change. County-level land-use systems play a critical role in national emission management and control. Consequently, it is essential to explore spatiotemporal effects optimization strategies emissions at county scale promote achievement regional dual targets. This study, focusing on Shaanxi Province, analyzed characteristics land use from 2000 2020. By establishing evaluation model, county-level were clarified. Utilizing Geodetector K-means clustering methods, driving mechanisms elucidated, explored. The results showed that during 2000–2020, Province underwent significant changes, with constructed increasing by 97.62%, while cultivated grassland substantially reduced. overall exhibited pattern North > Central South. total within province increased nearly fourfold over 20 years, reaching 1.00 × 108 tons. Constructed was primary source forest contributed significantly sink study area. Interactions among factors had impacts spatial differentiation emissions. For counties different types differentiated recommended. Low-carbon should intensify ecological protection rational utilization, medium-carbon need strike balance between economic development environmental protection, high-carbon prioritize reduction structural transformation.

The rational allocation of land use space is crucial to carbon emissions reductions and economic development. However, previous studies have either examined inter-objective trade-offs or intra-objective within a single objective lacked multilevel comprehensive studies. Therefore, this paper integrates inter- mitigation efficiency comprehensively study the interaction between pattern demand due policies. research methods were mainly multi-objective planning, gray model, patch-generating simulation area was less-developed urban agglomeration—the Tianshan north slope agglomeration. results show that total change from 2000 2020 5767.94 km2, grassland transferred out most, 3582.59 accounting for 62.11%, cultivated in 3741.01 km2. Compared with 2020, simulated obtained 2030 has significantly changed. In addition, benefits under low-carbon objectives changed opposite direction. four landscape patterns three scenarios same direction, degree fragmentation, agglomeration, regularity better than objective. are essential references future resource management, mitigation, sustainable development agglomerations.
