Benefit of the returning grazing land to protected grassland project was analyzed by assessment of direct economic values and indirect ecological service values on grassland ecosystem in wetland protection area of Maqu in the upper reaches of Yellow River. Results showed that aboveground productivity and vegetation coverage increased by 13.65% to 29.29% and 12.06% to 22.76% respectively after the project was conducted. The direct economic values of grasslands were 0.13 × 108 yuan and 0.10× 108 yuan for rest-grazing region and grazing-prohibition region in Maqu,which were increased by 28.84% and 21.55%,respectively. The indirect ecological service values of grasslands were 83.32 × 108 yuan and 78.62 × 108 yuan for rest-grazing region and grazing-prohibition region, which were increased by 18.64 × 108 yuan and 13.94 × 108 yuan, respectively. It revealed that the project significantly increased the direct economic benefits and indirect ecological benefits in Maqu.
