When accounting for the social-ecological impact of an ecological restoration program, both objective environmental contexts and people's subjective perceptions are required. While this kind of environmental impact assessment lacks a comprehensive perspective. We use the difference-in-differences model to evaluate the effect of the greenness of the landscape after ecological migration in the Qilian Mountains in China; and analysis of variance and fixed effects models are used to evaluate the effects of such ecological restoration programs on local people's perceptions. The results show that the ecological migration program in the Qilian Mountains has been successful at not only significantly improving remotely sensed greenness at the landscape scale, but also at enhancing immigrants' environmental perceptions. These findings demonstrate the environmental impacts of ecological migration from a social-ecological perspective, and can provide methodological implications for landscape planning to support a better understanding of ecological restoration programs in the drylands.
当考虑生态恢复计划的社会-生态影响时，需要考虑客观环境背景和人们的主观感知。虽然这种环境影响评估缺乏全面的视角，但我们使用双重差分模型来评估中国祁连山生态移民后景观绿化的影响；并使用方差分析和固定效应模型来评估此类生态恢复计划对当地人感知的影响。结果表明，祁连山的生态移民计划不仅在显著提高景观尺度的遥感绿化方面取得了成功，而且增强了移民的环境感知。这些发现从社会-生态角度展示了生态移民的环境影响，并为景观规划提供了方法启示，以支持更好地理解干旱地区的生态恢复计划。
