Social development and technological advancement have led to land use changes, influencing the structure of ecosystem services and severely impacting ecological balance. This study spatially and quantitatively assesses the effects of land‐use changes on ecosystem services based on the fourth assessment report of the Intergovernmental Panel on Climate Change (IPCC) and using the Integrated Valuation of Ecosystem Services and Tradeoff (InVEST) model. This model, applied on a global scale, was used to quantify the changes in three ecosystem services, namely, carbon storage, water yield, and sediment retention, 2010 and 2100 under four land use scenarios (A1B, A2, B1, and B2) and to evaluate the impact of land use changes to these services. The results indicate that (1) sediment retention and carbon storage under scenario B1 increase more than under other scenarios, with average global increases of 175.74 t/km² and 913.60 Mg/km², respectively; water yield increase only under scenario A2 between 2010 and 2100, with average global increase of 3.51 mm; (2) forest and grassland are the principal land types providing three ecosystem services globally, and decreasing the area of barren contributes to increases in three ecosystem services; and (3) when barren is converted to forest, grassland, cropland, and urban, ecosystem services all increase, strengthening the utilization of barren land can increase ecosystem services greatly. This study provides a reference for further research and the sustainable development of ecosystem services.

四种IPCC SRES土地利用情景下全球多生态系统服务变化的时空评估

社会发展和技术进步导致土地用途的变化，影响了生态系统服务的结构并严重影响了生态平衡。这项研究基于政府间气候变化专门委员会（IPCC）的第四次评估报告，并使用生态系统服务与权衡综合评估（InVEST）模型，在空间和数量上评估了土地利用变化对生态系统服务的影响。该模型在全球范围内应用，用于量化三种土地利用情景（A1B，A2，B1和B2）下三种生态系统服务的变化，即碳储量，水产量和沉积物截留量（2010年和2100年）并评估土地用途变更对这些服务的影响。²和913.60 Mg / km ²；仅在情景A2下，2010年至2100年之间的水产量增加，全球平均增加3.51毫米；（2）森林和草地是在全球范围内提供三种生态系统服务的主要土地类型，减少荒地面积有助于增加三种生态系统服务；（3）当荒芜地转变为森林，草地，农田和城市时，生态系统服务都在增加，加强荒地的利用可以大大增加生态系统服务。这项研究为进一步研究和生态系统服务的可持续发展提供了参考。
