摘  要:
基于社会—生态系统适应性循环模型,以陕西省长武县王东村为例,通过对系统几个关键变量的观察,分析了黄土高原地区农村社会—生态系统适应性循环的演变机制;并从适应性循环周期中研究了系统的恢复力和适应性能力变化过程。结果表明,建国以来王东村社会—生态系统依次经历了一个完整的适应性循环(1949—1961年)、贫穷困境(1961—1980年)和新的一个适应性循环的前环阶段(1980至今);制度变革特别是土地制度的调整是系统循环过程的驱动力,而技术革新可以使系统维持在开发阶段;干旱等气候变化事件对系统具有强烈的扰动作用,并可能导致整个系统崩溃释放。

摘  要:
Based on the adaptive cycle model,the evolvement mechanism of social-ecological system was explored in a case study of Wangdong Village,Changwu County,Shaanxi Province.The dynamic adaptive cycles of Wangdong Village were identified by integrating key variables from social,economic,and ecological aspects.The social-ecological system of Wangdong Village has experienced a total adaptive cycle(1949—1961),then fell into a poverty trap(1961—1980),and now is in the exploitation phase of a new adaptive cycle(1980-).The institutional changes,especially the adjustment of land use policies,are the main driving force for the adaptive cycles.The technical innovation maintains the current system in the exploitation phase.Climate change such as drought is a strong disturbance to the social-ecological system and may lead the system into a releasing phase.
