Title: The analysis and evaluation on grassland ecosystem service function value of Shandan Horse Field in Qilian Mountain National Nature Reserve
Abstract: The evaluation on grassland ecosystem service function value based on maintaining the structure,characteristics and processes plays an important role in formulating reasonable regional ecological economic development decision,protecting and restoring the grassland ecosystem,improving the consciousness of the environment resource.The 8 ecosystem services values of grassland of Shandan Horse Field in Qilian Mountain National Nature Reserve were assessed and evaluated by the market value method,the reforestation cost method,the shadow engineering method,replacement cost method and other methods.The result shows that the annual ecosystem service function value of the grassland in Shandan Horse Field is about 58.024 ×107 Yuan,among them the products providing function value is 1.840 × 107 Yuan;the regulating function value is 56.160×107 Yuan;the cultural function value is 0.0240×107 Yuan.Of all the value contributions of various service functions,water source conservation and climate regulation hold the largest proportion,which accounted for 45.481% and 39.277% respectively of all values.Therefore,protecting the grassland ecosystem of Shandan Horse Field is of the great significance to curb the deterioration of the ecological environment on North Slope of Qilian Mountains and maintain ecological safety of Hexi Corridor.
