Study On Spatial Differentiation And Influencing Factors Of Poverty Of Qinba Mountain Region

Rural poverty has plagued the process of China's social and economic development.It is of great significance to study the factors that induce poverty and explore the mechanism of poverty.It is of great significance for China to carry out poverty alleviation and prepare poverty alleviation plans.The 13 th Five-Year Plan for Poverty Alleviation requires that by 2020,all the poor will be lifted out of poverty as scheduled.At present,China is in the stage of poverty alleviation and determination,and requires more precise identification of the geographical differentiation characteristics of poverty space and its influencing factors to ensure the accurate implementation of various poverty alleviation measures.Based on the National Natural Science Foundation of China and the Humanities and Social Sciences Planning Fund Project of the Ministry of Education,relying on the key laboratory platform of the Ministry of Education,the key counties of the poverty alleviation and development planning in Qinba Mountain Area and the Yiyu County,a key poverty alleviation and development county in the country,are selected as research areas and grouped by GIS.Statistical analysis and spatial autocorrelation analysis explored the spatial distribution pattern of rural impoverishment in Yilong County;using Pearson correlation analysis,spatial superposition coupling and geographic detector model to comprehensively determine the main factors affecting rural poverty in Yilong County,analyze and discuss the main factors Influencing factors and the incidence of poverty in spatial characteristics;taking the main factors as independent variables,the incidence of poverty as the dependent variable,using the geo-detector model to detect the regional differentiation mechanism of the main factors of poverty;finally analyzing the main domestic poverty alleviation models,ceremonies The county poverty alleviation model combines the poverty-stricken areas derived from the research to optimize the poverty alleviation model.The conclusions of this paper are as follows:(1)The spatial distribution of poverty incidence in Yilong County has obvious aggregation characteristics,and has a significant spatial positive correlation pattern,forming two hot spot gathering areas and one cold spot gathering area.(2)The main influencing factors affecting the differentiation of poverty-stricken areas in Yilong County are elevation,NDVI value,distance to the county center,distance to major highways,per capita net income of farmers,total grain output,pig slaughter,cultivated land area,minority population The proportion of the proportion,the low-income rate,the proportion of major illness insurance,the proportion of dangerous housing renovation,and the 13 households of the farmhouse cover the four dimensions of the natural environment,geographical location,economic conditions and social factors.(3)According to the degree of influence of various factors,four types of impoverished regions are divided: natural environment constraints,geographic location constraints,economic conditions constraints and social factors constraints.Based on the dominant factors of poverty-stricken geographical differentiation,combined with the current Yizheng County poverty alleviation reality and precise poverty alleviation theory,scientific and accurate suggestions are put forward,and the implementation of precise poverty alleviation and precision poverty alleviation strategies for other poverty-stricken areas can be used for reference.(4)There will be interaction enhancement between the factors affecting regional poverty.Therefore,the impact of this factor on regional poverty should be taken seriously,and poverty alleviation measures under different circumstances should be comprehensively considered to ensure the effective implementation of poverty reduction.At the same time,we must improve the various poverty alleviation work guarantee mechanisms and coordinate all poverty alleviation work arrangements.
