In order to demonstrate the status and the trend of water environment carrying capacity，the fuzzy matter-element model coupled with entropy weight method was adapted to calculate the proximity between the water environment carrying capacity and standard samples in the area of Muping district，Yantai City from 2005 to 2009． A total of seven indices were selected． The results show that the proximity between the water environment carrying capacity and standard samples were 0． 804 7，0． 684 2，0． 666 7，0． 675 3，and 0． 696 1 from 2005 to 2009，respectively． The water environment carrying capacity were at level Ⅲ in 2006 and 2009，while the other three years were under level Ⅲ，indicating poor water environment carrying capa-city of the investigated area． Furthermore，suggestions were made on improving the water environment carrying capacity and promoting the sustainable development of society and economy．
