摘　　要：定量测度社会-生态系统恢复力,探索研究社会-生态系统在外部干扰下的适应性循环演化过程和机制。通过对研究区域相关利益主体进行访谈、问卷调查,以及查阅相关文献资料,建立起社会-生态系统对干旱恢复力的计算模型,分析系统的适应性循环过程与机制。1985—2009年间,系统恢复力的变化趋势在整体上呈现了从增高到走低、再增高的过程,系统相应地经历了"开发-保护-释放-更新"这样一个适应性循环过程。半干旱区社会-生态系统恢复力的大小由干旱胁迫压力和系统对干旱的敏感程度所决定,政策影响、技术创新和干旱扰动则是影响榆中县北部山区社会生态系统适应性循环演变的主要驱动因素。To calculate the resilience of social-ecological system （ SES）, and research the process and mechanism of the adaptive cycle experienced by SES under the external disturbances. Based on the study of the stakeholders＇ interview, questionnaire survey and literature review, the quantitative calculation model of the resilience of SES was built, and the process and mechanism of the adaptive cycle were analyzed. The results of resilience value c as ＂rise, fall and rise＂ in 1985-2009, which indicated that the SES has experienced a complete adaptive The results of resilience were determined by drought stress and the sensitive degree of the system to the effects of drought, policy and technological innovation are the main driving forces in this adaptive hanged drough cycle. t, and cycle process.
