Multi-Scenario Simulation of Land Use Changes Integrated with Functional Zoning:A Case Study of Jianyang District of Nanping,Fujian Province,China
Multi-scenario simulation of land use change is a prerequisite for rational allocation of land resources.Previous research focused on larger-scale regions,such as provinces and urban clusters.Little attention was paid to the land use changes and the associated ecological security constraints of southern small mountainous towns.In this study,it utilized the RSEI-MCR-PLUS model to delineate the land functions in Jianyang district,Nanping city,Fujian province,China,integrating land functional zoning under ecological constraints into land-use change simulations.Simulations and comparative analyses of the spatial patterns of land-use in 2030 were conducted under four distinct scenarios:inertia development,economic development priority,ecological protection priority,and sustainable development.It found that(1)in the Jianyang district,it could divide into four zones:suitable development zones,buffer development zones,restricted development zones,ecological buffer zones and ecological protection zones,accounting for 3.17％,27.94％,26.73％,25.68％,and 16.48％of whole area,respectively.Each functional zone spatially arranged in a ring around the suitable development zone.(2)In the inertia development scenario,construction land expanded in a multi-point diffusion pattern,poor utilization of land resources.In contrast,under the economic development priority scenario,new construction land encroached forest land and arable land,exacerbating spatial conflicts.In the context of the ecological protection priority scenario,it resulted in low efficiency in the use of land resources,thereby curtailing economic development.As for the sustainable development scenario,construction land developed in clusters,ensuring ecosystem protection and proper land resources disposition.Our findings provide a scientific reference for optimizing regional land space development and conservation pattern and sustainable use of land resources.
