It is one of the important strategies during the poverty alleviation to maintain a basic balance between the eco-environment and economic development in poor areas. Taking the whole 20 counties in Lüliang national contiguous special povertystricken areas and the surrounding 36 counties as multitype and multiscale typical study areas, the relationship between eco-environment quality and poverty in the povertystricken areas was explored in this paper. Firstly, the region’s ecological poverty index system was systematically built, and by integrated use of the subjective and objective weighting method, the ecological environment quality was evaluated in the perspective of natural environment. Then, the coupling coordination degree was calculated by coupling the ecologi-cal environment quality index and the average disposable income. Finally, the spatial variation was analyzed in detail respectively at provincial, city and county scales. Results showed that as a whole, the spatial autocorrelation coefficient of coupling coordination degree was relatively higher in the study area, and the coupling coordination degree in the eastern part was higher than that in the western part; the whole coupling coordination degree in Shanxi Province was slightly higher than in Shaanxi Province; the national poverty counties presented a state of recession, and their coordinated development degrees were far lower than that of nonnational poverty counties.
