A three-tier analytical framework — comprising ecological function identification, process simulation, and resilience-oriented regulation — is developed. By integrating Multi-scale Patching and Spatial Analysis (MSPA), dynamic resistance surface modeling, and circuit theory, ecological sources and corridors are accurately identified. A dual-dimensional resilience assessment system based on the “source–corridor” structure is constructed to examine the spatiotemporal evolution of the ecological network from 2000 to 2020. The results reveal that: (1) Ecological service functions increased by 22.45% from 2000 to 2020, although growth slowed after 2010. Meanwhile, the Ecological Risk Index (ERI) rose by 12.5%, with high-risk zones expanding from 14% to 16.3% and shifting northward by 12.6 km, indicating a mismatch between functional gains and risk control; (2) The number of ecological sources decreased by 17% between 2000 and 2010 but rebounded by 8.8% from 2010 to 2020. However, fragmentation intensified, as evidenced by a 21.7% decrease in the largest patch index (LPI), leading to disrupted ecological stability and reduced resilience of source areas;(3) An ecological security pattern — “one core, two zones, two belts, and multiple corridors” — is proposed to enhance network connectivity and mitigate regional ecological threats, particularly wind erosion and soil degradation.

The process involves adjusting the ecological protection costs within the Marxan model by accounting for impacts of resource-use zoning on ecological conservation. The goal is to optimize both ecological and comprehensive zoning, while evaluating the spatial structure and overall benefits of comprehensive zoning optimized schemes. The recommended comprehensive zoning optimized scheme allocates 34.19 % and 2.95 % of the area to ecological preservation zones and ecological control zones, respectively. Marine development zones and reserve zones account for 27.22 % and 35.64 % of the area. Ecological preservation zones effectively fulfill protection objectives, while control zones and reserve zones serve to buffer preservation areas from development zones, safeguarding sufficient spatial resources for future marine development. During the evaluation of the optimized scheme, ecological preservation zones and reserve zones each account for approximately 35 % of the area, with the developed coastline comprising no more than 30 %. More than 35 % of typical cross-sections are in an ecological preservation state, while 40 % are in a reserved state. Additionally, the recommended scheme optimizes protection costs, the compactness of preservation zones, and economic benefits.

Therefore, this study focuses on the ecological restoration Program region in China - the Three-North Shelter Forest Program (TNSFP). By combining the carbon emission coefficient method with Exploratory Spatial-Temporal Data Analysis (ESTDA), this research provides a visual analysis of the spatial patterns and trends of land use carbon emissions in the TNSFP region of China. We found that from 1995 to 2020, the total carbon emissions from land use in the TNSFP region increased from 2.78 × 10<sup>8</sup> tons to 8.39 × 10<sup>8</sup> tons, representing a threefold increase. Land use carbon emissions exhibited a significant positive spatial autocorrelation, with spatial convergence showing a trend of initially decreasing and then increasing. The spatiotemporal pattern of land use carbon emissions displayed clear path dependence and lock-in spatial characteristics, with a gradual weakening trend. We emphasize that urbanization has been the primary driver of carbon emissions in the TNSFP region, and traditional ecological conservation and afforestation policies aimed at enhancing carbon sequestration have proven insufficient in curbing the rise in carbon emissions. The findings offer new insights into the spatial patterns and trends of land use carbon emissions in China's ecological restoration regions, providing a deeper understanding.
