Based on the construction of the coupling coordination evaluation index system of rural protduction,life , and ecology composite system , the coupling coordination degree of the three rural " Sheng”composite system in l6 prelecture levelcities of Anhui Province from 2010 to 2019 is calculatedl by entropy method and coupling coontination measurement model ,and its temporal and spatial characteristics and evolution are compared and analyzed.Tlhe results show that the comprehensive development level of rural production life ecosysltem in l6 prefecture level cities of Anhui province fluctuates but rises ;the coupling and coordination of the nural " three health" composite system has seven evolutionary levels ;moderate imbalance , mild imbalance , almost imbalance , reluctant cootlination , primary coontination , moderate coordination and goodcoordination.In general, it has gone through the process fmom rise to fall and rise aain ,and most cities have increased indifferent degrees in the past 10 years.The coupling and coordinating evolution of the three rural "Sheng”composite function is obviously regional heterogenous.
