In this research, we analyzed the evolution of the coupling relationship between vulnerable ecological environments and poverty in the study area from 1995 to 2015 by establishing an evaluation system of ecological environment and poverty, and the coupling relationship between the two systems in the study area from 2020 to 2040 was predicted and simulated by using the system coupling model and GM (1,1) prediction model. The results showed that: (1) From 1995 to 2015, the poverty index of contiguous povertystricken areas in Hebei, declined from 0.902 to 0.761, and the ecological environment vulnerability index also declined slightly, from 0.438 to 0.412.(2) From 1995 to 2015, the type of coupling between poverty and ecological environment in contiguous povertystricken areas in Hebei changed from an antagonistic period to a runningin period, and the type of coordination changed from mild imbalance to on the verge of decline. Counties with lowlevel coupling were found to be mainly distributed in the northern Taihang Mountains. The degree of coupling coordination was high at both ends and low in the middle. The degree of coupling coordination of the counties in the northern Yanshan Mountains and the southern Taihang Mountains was generally high. (3) The ecoenvironment vulnerability index and poverty index in the study area were both predicted to show a decreasing trend from 2020 to 2040. The coupling degree of the two showed a continuous improvement. The coupling type was in the runningin stage, close to highlevel coupling. The degree of coupling coordination showed a continuously decreasing trend. The type of coordination changed from verge of decline type to barely coordinated type. It concludes that the key to the coordinated development of ecological environment and economy in the region is to rapidly improve the economic development of the region. %R %U http://cjarrp.com/zgnyzyyqh/ch/reader/view_abstract.aspx %1 JIS Version 3.0.0
