- Abstract:
- In order to promote the coordinated development of urban and rural construction and ecological protection, and realize the rational optimization of urban-rural residential land use in Tang County, we used the least cumulative resistance model to obtain ecological security protection zones, and used the GeoSOS-FLUS model to predict the urban-rural residential land use change, analyzed the interactive relationship between the evolution of urban-rural residential land and the pattern of ecological security in the future, and explored the spatial characteristics of ecological suitability of urban-rural residential land in the county from the perspective of ecological protection and construction, optimized the spatial layout of urban-rural residential land in Tang County by combining the ACO model. The results show that:(1)the overall ecological security value of Tang County is on the low point, showing the characteristics of spatial differentiation between low in the northwest and high in the southeast;(2)in the natural development scenario, the total area of urban-rural residential land in Tang County will increase by 6.67 km2 by 2027, and the spatial expansion of urban-rural residential land is concentrated in low ecological security protection areas and lower ecological security protection areas, which will gradually threaten the ecological security of Tang County in the future;(3)the ecological suitability zoning of urban-rural residential land can be divided into highly suitable areas, more suitable areas, medium suitable areas, less suitable areas and unsuitable areas, accounting for 2.83%, 15.39%, 17.02% and 64.76% of the total area of Tang County, respectively; after optimization, the urban-rural residential land will show a tendency to migrate to areas with higher suitability, most of the urban-rural residential land will show large-scale agglomeration distribution, and the overall layout of urban-rural residential land will tend to be compact. Optimizing the spatial layout of urban-rural residential land from the perspective of ecological protection and construction is more in line with the development requirements of urban-rural residential land under the background of ecological civilization construction and rural revitalization strategies, and can provide a scientific reference for the future planning and development of urban-rural residential land in Tang County.
