Abstract: The improvement of the soil physical and chemical properties is the most important foundation for mine ecological restoration. The experiment is aimed at undisturbed area, restored area, and damaged area of abandoned Yongledian Quarry in Beijing. Through determination and analysis of soil physical and chemical properties, it shows that there are significant differences in the composite effects of soil physical and chemical properties between restored area, and undisturbed area, damaged area, and engineering restoration effectively improves the composite effects of soil physical and chemical properties in the restored area. The single factor hypothesis test shows that soil pH value, organic matter, alkali-hydrolyzable nitrogen, and total nitrogen traits are the key targets to be restored in this mining area.
