中文摘要	天然草原是甘肃省最大陆地生态系统,是全省乃至全国的重要生态屏障,科学、准确地估算甘肃省天然草原生态系统服务价值,对甘肃草原重要性认识和生态安全维持具有重要意义。本研究利用甘肃省主要粮食作物产量和价格数据,计算出甘肃省生态系统服务价值基准单价,然后结合甘肃省各种草原类生物量,修正甘肃省草原生态系统服务价值当量,最后计算出甘肃省各类草原生态系统服务价值。结果表明:1)草原提供的其他单项生态系统服务价值均在食物生产和原材料生产价值的3.1倍和3.7倍以上;2)甘肃省暖性灌草丛单位面积生态服务价值最高,为84 418.28元·hm~(-2),温性荒漠单位面积生态服务价值最低,为10 120.21元·hm~(-2);3)甘肃省草原生态服务总价值为7 069.73 * 10~8元,是2016年畜牧业总产值的23倍,约等于甘肃省2016年国民生产总值(gross domestic product, GDP); 4)高寒草甸生态系统服务总价值最高,为1 733.27 * 10~8元,占草原生态系统服务价值的24.52%;高寒荒漠生态系统服务总价值最低,为58.51 * 10~8元,占草原生态服务价值的0.83%。本研究不仅为区域内生态系统服务价值的估算提供了思路,也为利用法律手段保护草原提供了科学依据。
英文摘要	Estimation of the ecosystem service value of grasslands is important for understanding the importance of this land type and maintaining ecological security in Gansu Province. In this study, the benchmark unit price of the ecosystem service value of grasslands in Gansu Province was calculated using data of the main grain crops in the province. Combined with the biomass data of each grassland type, the ecosystem service value equivalent of each grassland type in Gansu Province was both revised and calculated. The results showed that 1) the value of other ecosystem services provided by grasslands was much greater than the value of the providing services; 2) the ecosystem service value per unit area of warm shrub herbosa in Gansu Province was the highest (84 418.28 CNY·ha~(-1)) and that of the temperate desert was the lowest (10 120.21 CNY·ha~(-1)); 3) the grassland ecosystem service value was 7 069.73 * 10~8 CNY, which was 23 times more than the total output value of animal husbandry in Gansu Province and almost equal to the gross domestic product of the province in 2016; and 4) the alpine meadow had the highest ecosystem service value (1 733.27 * 10~8 CNY), and its contribution rate to the grassland ecosystem service value in Gansu Province was 24.52%. The ecosystem service value of the alpine desert was the lowest (58.51 * 10~8 CNY), and its contribution rate was 0.83%. The data from this study provide a basis for the scientific and reasonable estimation of ecosystem service values and the formulation of punitive measures against players contributing to ecosystem damage.
