In the context of rapid urbanization and extreme climate change globally, balancing ecological resources and economic development for land spatial planning has become one of the pressing issues that need to be addressed.This study proposes a composite model to construct a spatial ecological security pattern.It identifies restoration areas with different risk levels based on the spatial distribution of land use, offering suggestions for optimizing spatial configuration.Focusing on the central Shaanxi region of the Yellow River Basin in China, ecological sources are identified by integrating ecological factors, and ecological corridors and restoration zones are extracted using the minimum cumulative resistance difference and circuit theory.
The results indicate Cable Clamps significant improvements in ecological quality and desertification in the study area from 2000 to 2020.Currently, the core area covers 51,649.71 km2, accounting for 62.18% of all landscape types; the total ecological source area covers 31,304.
88 km2, representing 18.84% of the entire area.These ecological source areas are mainly distributed in the northern Loess Plateau and the southern mountainous regions.The area has 26 important ecological corridors, identifying 16 ecological pinch points and 12 ecological barriers, presenting an ecological security pattern characterized by a grid-like structure in the northern region and a dispersed pattern in the southern region.
Additionally, 273.72 km2 of ecological restoration priority areas and 197.98 square kilometers of ecological restoration encouragement areas are proposed as key planning regions for ecological environmental protection.This study provides references DEODORANT for optimizing spatial configuration to promote the sustainable development of urban and rural living environments in the Yellow River Basin.
