| Abstract: |
| Taking Yilong, one of poverty counties in Sichuan province, China as the research object, this research reveals the spatial pattern and spatial distribution characteristics of impoverishment in Yilong, and proposes corresponding countermeasures based on the spatial autocorrelation analysis and GIS spatial expression. The research used the geographical detector model to detect and analyze the influencing factors of pauperization in Yilong county, and analyzed the leading factors affecting poverty in Yilong county, and divided different types of pauperization region. It was found that the spatial distribution of impoverishment in Yilong county showed some certain agglomeration characteristics, and there were high value hotspots and low value cold spots in poverty incidence. The elevation, the distance to the center of the county, the total grain output, the proportion of minority population, the proportion of major illness insurance, and the proportion of dangerous housing renovation were the main six factors that restricted the differentiation of impoverished areas in Yilong county. When different factors interacted with each other in the poverty incidence, the effect was greater than that of a single factor. There were four types of poverty oriented regions in Yilong county, namely, natural environment restriction, geographical location restriction, economic condition restriction and social factor restriction. It is concluded that the comprehensive action of various factors leads to the formation of regional differentiation mechanism of poverty in Yilong county. Efforts should be made to improve the guarantee mechanisms for poverty alleviation work, to ensure that all work arrangements are coordinated, and to implement policies scientifically and accurately according to local conditions in the future. |
