In special poverty-stricken rural areas, the primary problem of poverty alleviation is effective targeting and identifying of the poor and their distribution area. In recent years, researchers around the world focused on grasping the essence of multidimensional poverty and measurement. Based on systematic design of multidimensional poverty identifying indices system and algorithm flow, this article takes key country in Nanyang, Henan Province from national contiguous special poverty-stricken areas as the study area, constructs algorithm based on the"dual cutoff"and "dimension aggregated/decomposition" to measure and analyze the multidimensional poverty of the poor at "county-village" scale,uses Kriging method to interpolate results of multidimensional poverty measurements and systematically analyze spatial distribution pattern of multidimensional poverty at village scale in study area.The result shows: in the study area,the trend of multidimensional poverty headcount ratio and multidimensional poverty index(MPI) is that the value of west is higher than that of the east;the MPI of Neixiang country and Xichuan country is the highest,that of Zhenping country is the lowest.Their primary factors contributing to poverty are income and health,contribution of income index to the poverty appears as strip from "northwest-southeast",healthy problem mainly concentrates around Zhenping country. Their secondary factors contributing to poverty are education,schooling and fuel.Besides,the multidimensional poverty incidence is the highest in mountainous area in Xichuan country,MPI is relatively lower around the center of the country.
