Changes in land use can cause significant changes in the ecosystem structure and process variation of ecosystem services. This study presents a detailed spatial, quantitative assessment of the variation in the value of ecosystem services based on land use change in national nature reserves of the Ningxia autonomous region in China. We used areas of land use types calculated from the remote sensing data and the adjusted value coefficients to assess the value of ecosystem services for the years 2000, 2005, and 2010, analyzing the fluctuations in the valuation of ecosystem services in response to land use change. With increases in the areas of forest land and water bodies, the value of ecosystem services increased from 182.3×10(7) to 223.8×10(7) US$ during 2000-2010. Grassland and forest land accounted for 90% of this increase. The values of all ecosystem services increased during this period, especially the value of ecosystem services for biodiversity protection and soil formation and protection. Ecological restoration in the reserves had a positive effect on the value of ecosystem services during 2000-2010.
土地利用变化会导致生态系统结构和生态系统服务过程变化的重大变化。本研究基于中国宁夏回族自治区国家自然保护区的土地利用变化，对生态系统服务价值的变化进行了详细的空间、定量评估。我们使用从遥感数据计算的土地利用类型面积和调整后的价值系数来评估 2000 年、2005 年和 2010 年的生态系统服务价值，分析了生态系统服务价值随土地利用变化的波动。随着林地和水体面积的增加，生态系统服务的价值从 2000 年到 2010 年从 182.3×10(7) 增加到 223.8×10(7) 美元。其中 90%是由草地和林地贡献的。在此期间，所有生态系统服务的价值都有所增加，特别是生物多样性保护和土壤形成与保护的生态系统服务价值。2000-2010 年保护区的生态恢复对生态系统服务价值产生了积极影响。
