| Dynamic Evolution of Natural Resources in Liaoning Province Based on Multi-scale Comprehensive Zoning |
| This study utilized multi-source geospatial data and GIS technology to conduct comprehensive natural resource zoning in Liaoning Province. Spatiotemporal changes and driving mechanisms from 2000 to 2020 were systematically analyzed, to provide a basis for provincial territorial governance and optimal resource allocation. A three-level evaluation index system covering environmental geography, natural resources, and functional suitability was established by dividing Liaoning Province into three primary zones, 27 secondary subzones, and 108 tertiary functional zones. The study showed a net increase of 8 420 km2 (+11.8%) in forestland area, a decrease of 6 350 km2 (–15.5%) in arable land, and a 4 180 km2 expansion in construction land. Three typical transformation zones were identified: forest expansion and farmland reduction in eastern Liaoning, farmland expansion and forest reduction in central Liaoning, and stable forestry and farming in western Liaoning. Natural resource evolution is driven by policy regulations, socioeconomic factors, natural endowments, and regional strategies, exhibiting distinct regional adaptability and functional synergy. Based on the zoning results, this study proposes the following zonal governance approaches: strengthening ecological conservation and water source protection in eastern Liaoning, ensuring agricultural security and black soil preservation in central Liaoning, and promoting grassland pastoralism and ecological transformation in western Liaoning. It suggests establishing an integrated sky–air–ground monitoring network and a closed-loop governance system of monitoring –evaluation–control–optimization to enhance refined natural resource management and spatial governance efficiency in Liaoning Province. These recommendations provide systematic solutions and practical references for achieving high-quality regional development and ecological civilization construction. |
