Compounds that promote vegetation diversity key to ecological restoration in open-pit coal mine dumps

Researchers find interesting restoration results at the Antaibao open-pit coal mine.

demonstrates that soil urease and β-glucosidase are key supporters of the diversity of vegetation configuration which, in turn, is an important factor when it comes to the ecological restoration in open-pit coal mine dumps.

plantations significantly shifted due to the invasion of surrounding plants, which resulted in an obvious increase in species number and vegetation coverage. “We chose to study the Antaibao open-pit coal mine located in the eastern Loess Plateau, where some artificial restoration projects began in 1992,” Chen said in a media statement.

Additionally, the secondary succession also changed the soil microbial community structure and function. The relative abundance of thegenus which dominates the nitrification increased 5.2-fold. This result suggests that the invasion and diffusion of native plants and surrounding plants had a positive effect on ecological restoration, which is helpful to explore more reasonable selection and configuration of vegetation in the practice of mine ecological restoration.
