英文摘要	The semiarid regions are one of the core areas in the construction of ecological civilization in China. Previous studies have shown that afforestation was an effective way for the ecological restoration to prevent soil degradation in the semiarid regions of North China. Unfortunately, little is known about the genetic information of these afforested plant populations, resulting in the defective assessment of the population stability and conservation in the process of ecological restoration under climate change. In this study, using maternally and bi-parentally inherited markers, genetic diversity was estimated in 5 artificial and 12 natural populations of Caragana korshinskii. The significant genetic differentiation was found among the artificial populations, and it could not support their population persistence in the restoration ecosystems. Compared to the natural populations, the artificial populations harbored much lower genetic diversity in both nrITS and cpDNA, which indicated that mating might be greatly limited and unbalanced among the germplasms. Based on the ecological niche modeling analysis, we proposed that both the natural and artificial populations were at a great risk of facing the impact of climate change, although the artificial populations were afforested in the optimum areas. These results suggested that it was necessary to assess the genetic diversity of founder populations before afforestation, and to conduct genetic rejuvenation for the defective artificial forest. This study proposed a pragmatic approach to guide the sustainable afforestation and provided the molecular evaluation on the ecological restoration in the desert areas of North China.
