| 英文摘要 | Windbreak and sand fixation services (SR) provided by grasslands are a joint result of climate change and human activities. Series of grassland protection measurements have been successively implemented on Inner Mongolia grasslands since 2000, but their effects on SR remains unclear. Based on satellite-derived vegetation dynamics and the Revised Wind Erosion Equation (RWEQ) model, this paper developed a method for quantitatively separating the impact of human activities on SR and revealed the contribution of human activities to SR in the Inner Mongolia grasslands from 2000 to 2020. In 2020, the actual sand fixation (SRA) of Inner Mongolia grasslands was 12.50 tha-1, spatially characterized as lower in the eastern and western parts, which was dominated by the sparse vegetation coverage and the low potential wind erosion respectively, while higher in the central part, due to the grassland vulnerability. The human-driven sand fixation (SRH) of Inner Mongolia grasslands changed from -1.28 tha-1 to -0.14 tha-1 from 2000 to 2020, indicating human activities inhibited SR, but the inhibition was gradually weakened. In semidesert and meadow steppes, the SRH changed from -3.00 tha-1 to 0.00 tha-1 and -0.16 tha-1 to 0.00 tha-1, respectively, which showed that the effect of human activities changed from inhibition to promotion. However, it should be noted that human activities still inhibited the SR in typical steppes. The results implicated that grassland ecological protection should pay much more attention to reasonable use of vulnerable typical steppes. Future grassland use requires quantitative evaluation on the effects of human activity for precise monitoring and sustainable management. |
