摘要：

轮牧被自然科学家认为是保护草地的自然解决方案之一。然而，当牧民采用轮牧时，其对改善草地质量的效果尚不明确。基于中国两个主要牧区的牧户面板数据，本文利用固定效应模型、工具变量法实证分析轮牧对草地质量的影响。结果显示，轮牧在短期内对草地质量的影响不显著，但在长期内具有显著的正向效果。当村庄投资能提高生产效率的公共基础设施或牧民采取轮牧相关的支持措施时，轮牧可以更好地改善草地质量。进一步分析表明，采用轮牧措施的牧民具有更高的放牧强度、更高的补饲强度和更多的圈养牲畜天数，这表明牧民可以在不增加对天然草地压力的情况下更有效地管理牲畜。此外我们还发现，牧业收入和轮牧采用相辅相成，这也是牧户采取轮牧的经济原因。这些研究结果为在发展中国家推广协调生态系统保护和资源利用的基层政策提供了参考。

Abstract: Rotational grazing is considered as one of the nature-based solutions (NbS) to grassland protection by natural scientists. However, its effects on improving grassland quality are still unclear when it is adopted by herders. Using a household-level panel data from field survey in two main pastoral provinces of China, empirical results from fixed-effect model and instrumental approach show that rotational grazing practices have insignificant short-term effects on grassland quality, but have positive long-term effects. In addition, rotational grazing practices can improve grassland quality when villages invest public infrastructure or herders have private supporting measures for more efficiency livestock production. Further analysis shows that herders adopting rotational grazing have higher grazing intensity, higher supplementary intensity and more livestock-house-feeding days, which indicate herders can utilize more efficient livestock management without increasing pressure on natural grassland. We also find that herders with pastoral income are more likely to adopt rotational grazing practice. These insightful findings offer policy implications on promoting grassroot NbS for ecosystem protection and resource utilization in developing pastoral countries.
