Abstract Wetland is amongst the richest life-supporting ecosystems on earth, and it is cradle of biological diversity, providing the water and primary productivity upon which countless species of plants and animals depend for survival. The Juyan Lake is located in the arid area of China. Based on the reference of the 17 major valuating parameters and methods proposed by Costanza et al and others, the market value approach, reforestation cost approach, shadow project method, and contingent valuation method are used to assess the wetland ecosystem service values of the Juyan Lake Wetland. Results show that the annual ecosystem service value of the Juyan Lake Wetland is about 11 523.33×104 Yuan in 2007, among which the sand fixation value occupies the highest proportion of about 3 149.76×104 Yuan; the gas regulation value is 2 007.55×104 Yuan; the biodiversity value is 1 152.28×104 Yuan; the cultural value is 1 504.3×104 Yuan; the recreation value is 1 339.8×104 Yuan; the material production value occupies the smallest proportion of about 130×104 yuan.
