摘　　要：农业干旱灾害是限制河南省农业发展的主要制约因素。以河南省为研究对象,构建了社会—生态系统干旱恢复力模型,以区域性干旱作为扰动因素选择水分敏感因子,给出了干旱压力、恢复力的计算公式,分析了2000～2010年间河南省社会—生态系统的干旱胁迫压力、恢复力变化趋势;对河南省各城市多年平均恢复力水平进行了分区,计算了各城市对干旱恢复力的适应水平。Agricultural drought disaster is one of the main influencing factors which limit the development of country agricultural. Taking Henan Province as research object, restoring force model of social ecosystem is established. Selec- ting moisture sensitive factor as regional drought to be a disturbance factor, this paper deduces the quantitative model of drought pressure and drought resilience. And then it analyzes the variation trend of social-ecological system＇s drought pressure and resilience during 2000 and 2010. Finally, we make the partition of an average of drought resilience＇s level in Henan Province, and calculate the adaptation level of drought resilience in each city.
