With the growth of the city's economy,its ecological environment is facing major challenges.A series of problems such as the deterioration of the ecological environment,the increase of environmental pollution,and the insufficient construction of the ecological environment threaten the sustained and coordinated development of the economy.In this paper,taking the ecological economic zone of Aba Prefecture in Western China as the research object,the coupled coordinated development model is used to evaluate the ecological environment and economic coupling coordination of Aba Prefecture from 2008 to 2017.The entropy weight method is used to determine the index weight,and the gray correlation model measurement is used to obtain the correlation and coupling of the ecological environment and the economic system,and then we can identify the main stress and constraint factors.This research shows that,from the perspective of coupling relationship,the correlation between the element layer and the index factor between the ecological environment and economic systems of Aba Prefecture in 2017 is higher than 0.59,which is a medium correlation.From the perspective of time evolution,Aba Prefecture and its counties have achieved varying degrees of progress in the ecological environment and economic coupling coordination level from 2008 to 2017,and the coupling coordination level is relatively high.Meanwhile,forecast analysis shows that the coupling and coordination level of Aba Prefecture and its counties in the next 5 years will roughly continue the development trend of 2008-2017.By 2022,all counties and districts will reach the high-quality coupling coordination category.
