Abstract：Rural poverty is one of the main obstacles to building a well-off society in China. Aiming at the demand of precise poverty alleviation strategy aiming at the poor villages and the poor population, aiming at analyzing the spatial distribution characteristics of poverty and the changes of economic development in the pilot project of Changsha-Zhuzhou-Tan-Heng urban agglomeration, this paper analyzed the spatial distribution characteristics of poverty in the study area by using GWR model, average night light intensity and average annual growth rate, and studied 2015-20 from three perspectives of city, county and village. The changes of light intensity in the past 18 years show that the distribution of poverty-stricken villages in Changsha-Zhuzhou-Tan-Heng urban agglomeration has a strong global spatial dependence, showing a clustering in the southwest and a sparse in the northeast. Hengyang City and Zhuzhou City are the agglomeration areas of poverty-stricken villages, and there are several massive dense areas of different scales at the same time. The natural growth rate and the number of enterprises in service industry above the scale are positive indicators of the number of poor villages, while the per capita disposable income is negative indicators. Overall, the average luminance of all prefecture-level cities or districts and counties increased to a certain extent during the period of 2015-2018. In 740 poor villages, 93.7% of the poor villages have an average annual growth rate of more than 20%, and 259 poor villages have an average annual growth rate of more than 50%. The economy of most poor villages has improved greatly in the past three years, and the state\'s precise poverty alleviation policy has achieved remarkable results.
