Evaluating the adaptability of the resource system to the green development of the city is the key to judging the health of the city.By constructing the evaluation system of"sys-tem pressure index,the distance between good and bad solutions(TOPSIS)and decoupling elasticity model(Tapio)",we quantitatively calculate and analyze the decoupling degree(S)be-tween the pressure of WEF system and the quality of green transformation of cities in the mid-dle reaches of the Yangtze River Economic Zone from 2012 to 2021,and determine the appro-priateness of its resource system and green transformation.The decoupling degree(S)of the"water-energy-food"system(WEF)pressure and the quality of urban green transformation in the middle reaches of the Yangtze River Economic Zone from 2012 to 2021 is quantitatively calculated and analyzed as a driving force,and the appropriateness of the resource system and green transformation is judged.The study finds that:(1)The WEF system pressure in the mid-dle reaches of the Yangtze River Economic Zone fluctuates greatly.(2)The quality of green transition in the middle reaches of the Yangtze River Economic Zone shows a significant linear upward trend from 2012 to 2021.(3)The WEF system pressure and the quality of green trans-formation in the middle reaches of the Yangtze River Economic Zone have not yet formed a suitable relationship,Hubei province has reached a preliminary decoupling state,and the health degree of green development of the three provinces is as follows:Hubei＞Hunan＞Jiangxi.Therefore,Hubei should play a leading role in radiation,so as to build a green industry and en-ergy chain,strengthen green technology innovation,and give full play to the comparative ad-vantages of each province.
