基于农户尺度的黄土高原农村社会-生态系统体制转换

Shift of rural social- ecological system regimes in Loess Plateau based on rural household dimension

以黄土高原生态脆弱农区的社会-生态系统为例,基于农户尺度,通过对系统变量应对内、外部干扰下的响应过程的分析,研究近几十年来当地农户家庭的体制状态转换(Regime Shift)及其差异性,以抵抗外界干扰的适应能力为参考依据,评价转换结果,为我国乡村转型期的人地关系研究提供参考。结果表明:由于种植结构的变化和外出务工等因素的影响,当地农户家庭体制确已发生转换,从农户适应力的角度来看,其对乡村人地关系演变的这种适应和响应是有利的。

This research took the ecological fragile agriculture area on loess plateau as an example,explored the specific process of system response under the influence of internal and external disturbance and regime shift in recent years at rural household dimension,inspected the change of farmer＇s adaptability response to resist both inside and outside interference,to judge the results of the regime shift. The results show that local system has indeed occurred shift,but its shift degree was different,and affected the adaptability of system.
