Evolution and simulation of production-living-ecological space in Chengdu-Chongqing Urban agglomeration based on FLUS
To study the evolution and driving mechanism of production-living-ecological spatial pattern and set up different simulation scenarios is conducive to realizing coordinated and sustainable regional development of urban agglomeration.Based on the land use data in 2000,2010 and 2020 of Chengdu-Chongqing urban agglomeration,production-living-ecological space was divided.According to land use data in 2010 and driving factors such as natural environment,social economy and traffic location,FLUS model was used to simulate the production-living-ecological spatial pattern in 2020.The Kappa coefficient was 0.824.Based on this model factor,the distribution pattern of production-living-ecological spatial pattern in 2030 is predicted and compared with three single scenarios.The results showed that:(1)From 2000 to 2020,production space decreased by 1375.95 km2,living space increased by 2087.48 km2,and ecological space decreased by 736.8 km2.The center of gravity of production space and living space moved to the southeast in general,while the center of gravity of ecological space moved to the northwest in general.(2)Compared with the actual situation in 2020,it is predicted that the production space will increase by 1749.57 km2 in 2030,while the living space and ecological space will decrease by 58.9 km2 and 1685.37 km2 respectively,which is in line with the rapid development trend of urban and rural living land in the future.(3)Compared with the single spatial optimization scenarios,the comprehensive prediction of production-living-ecological space in 2030 is more consistent with the future development trend,and compared with the actual utilization of production-living-ecological space in 2020,urban and rural living land continues to grow,and the urbanization process maintains high-quality development.The research results can provide multi-dimensional and multi-angle reference for the future territorial space planning of Chengdu-Chongqing urban agglomeration and the symbiotic coordination of production-living-ecological space in the future.
