近30年来河南省国土"三生"空间转型特征及其情景模拟
Spatial Transformation Characteristics and Scenario Simulation for'Production-Living-Ecology'Space of Henan Province s Land in the Last 30 Years
摘要
Abstract
[Objective]The aims of this study are to exploce the pattern of land space change in Henan,and to provide important insights and basis for the local comprehensive land management and spatial planning control.[Methods]The diverse array of data sources,including land use distribution data spanning from 1990 to 2020,natural resource records,and socio-economic indicators were drawn.By crafting comprehensive system for recognize'production-living-ecology'spaces and leveraging geospatial information graph theory,the discernible patterns underlying the province's land transformation since 1990 were revealed.Additionally,the Future Land Use Simulation(FLUS)model was employed to simulate forthcoming trends in land use.[Results]Henan Province's landscape had been predominantly characterized by spaces devoted to agricultural production.The expansion of living spaces remained a sustained trend,with urban living areas growing notably faster than their rural counterparts.Simultaneously,green ecological spaces and other natural habitats had progressively diminished,punctuated by fluctuations in water-based ecological areas.The evolution of land space within Henan Province exhibited discernible phases.During the initial period(1990-2005),the transformation was predominantly marked by shifts from agricultural production spaces to living spaces,and a reconfiguration of ecological spaces into production zones.In the latter period(2005-2020),these transformations intensified,primarily manifesting as conversions from agricultural production areas to urban living spaces,along with dynamic interplays between residential and production zones.Analyzing the trend maps revealed a noteworthy progression.In the earlier phase,agricultural production spaces and urban living areas were prominent.In contrast,the later phase witnessed a considerable expansion of urban living spaces by a factor of 1.56 and rural living spaces by an astonishing 12.35.On the decline side,the contraction of rural living spaces in the latter period was substantially more pronounced than the reduction in urban living spaces,clearly indicating a pronounced trend towards urban-rural dichotomy in development.Through meticulous comparison across various spatial resolutions and temporal scales,we have determined that the optimal simulation spatial resolution for this study was 300 m,and the optimal simulation time point was 2035.The simulation results underscore that by 2035,Henan Province's land transformation will notably decelerate,with the primary focus pivoting towards the transformation of rural living spaces and agricultural production areas.[Conclusion]Consequently,land space management strategies should emphasize safeguarding and rejuvenating arable lands in Henan Province,and steer the balanced expansion of rural and urban living spaces.关键词
