As an important component of urban land resources

the land in urban river beach areas is closely related to the spatial and functional aspects of land outside the riverimpacted by the hydrological processes within the rive. Therefore

it is of great significance to comprehensively consider multiple factors inside and outside the river to achieve adaptive configuration of river ecological space

which can guide the construction of urban river ecological space. This article takes the Jinghe New Townsection as the research object

and uses InfoWorks software to effectively correlate the flood discharge space of the river with flood changes

analyzing the spatiotemporal distribution patterns of flood elements under different conditions. Based on the characteristics of flood elements such as inundation depth

inundation time

and flow velocity

a water channel spatial suitability level evaluation system is constructed to identify the suitability of water channel ecological space construction. The article proposes ecological spatial configuration strategies for river channels based on the current land use situation. The results indicate that:(1) the suitability of spatial configuration enlarges with the increase of distance from the river channel in the ecological space of the river channel;(2) Based on the horizontal characteristics of flood elements

the slope zone

buffer zone

and terrestrial zone are divided

and different vegetation types and engineering measures are selected according to the suitability of spatial configuration to achieve the coordination of space

resources

and landscape. This study not only provides rational and quantitative technical support for water related projects

but also provides scientific basis for effectively achieving the coordination and unity of land use and safety in river beach areas.
