Abstract:: In order to study the spatial coupling relationship between ecological vulnerability and economic poverty in Haiyuan County, Ningxia, and to reveal its spatial differentiation characteristics, based on statistical survey data and remote sensing data, geographic information technology, the village was used as a research unit, and an evaluation index system was constructed to analyze Haiyuan County's ecological fragility and economic poverty, spatial coupling relationship and differentiation rule. The results show that the overall ecological vulnerability of Haiyuan County is at a medium to high level, and the spatial differences are large. The spatial distribution pattern has strong agglomeration characteristics. The areas with high ecological vulnerability mainly distribute along rivers with high development intensity and frequent human activities, river valley areas and southern areas with high elevation and large topography; from the perspective of poverty, the proportion of administrative villages with moderate poverty and above in Haiyuan County is 55.72%, indicating that the overall poverty in the study area is relatively deep, and severe poverty and extreme poverty concentrate in the southern and western regions with high altitude, large slope and undulating terrain; from the perspective of the coupling relationship between ecology and economy, the degree of coordination between ecological fragility and economic poverty in the study area is low, and the proportion of coordinated and synchronous development is 10.71%, and the unbalanced environment is lagging. The number of administrative villages with unbalanced economic backwardness is the largest, and their spatial distribution relatively concentrate, mainly in the eastern and southern regions of Haiyuan County.
