Abstract: Evaluation of ecosystem service value of farmland shelterbelt on wind prevention and sand fixation is of vital importance to regional economic development and ecological environment protection. In this case, service function value of farmland shelterbelt on wind prevention and sand fixation in Xinjiang from 2007 to 2011 was evaluated by applying methods including market price and shadow price. Results showed that the total ecological service function value of the farmland shelterbelt in 2007 and 2011 was 7.35×10⁹ yuan and 1.28×10¹⁰ yuan, respectively. The soil protection value of farmland shelterbelt played a major role in the service function value on wind prevention and sand fixation. The increase of total ecological service value of farmland forest product and wind prevention and sand fixation were 1.765×10⁹ yuan. The soil protection value was the largest (8.24×10⁸ yuan), followed by sand fixation value (5.405×10⁸ yuan) and forest product value (4.005×10⁸ yuan). Due to the fact that the ecological service function value of the shelterbelt on wind prevention and sand fixation was tremendous, it was suggested that ecological service market compensation mechanisms and perfected evaluation method of ecological service function value should be established as early as possible, so as to transform the shelterbelt from ecological style to an ecological and economical style.
