摘要： Vegetation cover and related ecosystem services are key indicators for ecological restoration efforts. We simulated the dynamic changes of vegetation coverage and sand-fixing service in the Beijing-Tianjin sandstorm source control project area (BTSSCPA) in the period of 2000-2015 on the basis of long-term satellite data and the revised wind erosion equation. The response levels of sand-fixing service to vegetation coverage change were also analyzed. Results showed that the vegetation coverage in the BTSSCPA increased with fluctuation at an average rate of 0.34%/year, and the sand-fixing service was correspondingly enhanced with the average annual rate of 0.71%. Furthermore, the responsive levels of sand-fixing service to vegetation coverage change increased from 70% to 91%. We conclude that the vegetation restoration measures on sand-fixing gradually prevail and progress in the BTSSCPA. However, approximately 13% of the BTSSCPA still has poor responsivity and needs additional restoration measures for implementation. This research will contribute to quantify the effectiveness of vegetation restoration on ecosystem service enhancement, and identify the key implementation areas for further ecological restoration measures.
