China as a coal country, surface subsidence caused by underground mining hasbrought many environmental problems, and the pros and cons of the ecologicalenvironment directly determined the sustainable development of mining areas.Aiming at the rule of damaged ecosystems having self-healing capabilities,we studiedthe rules of ecological succession in different lives of mine subsidence, as well as therole of artificial improvement and aftereffect succession laws with method of spaceinstead of time development. The results showed that community diversity ofvegetation, soil fertility, soil microbial and root fungal diversity were recovered withthe mining lives. The processing inoculated by two AMF artificially improved bothplants and soil optimally. The synergistic aftereffects of two AMF and intercroppingimproved the rate of vegetation community ecosystem secondary succession andprotected the biodiversity. By comparing the lasting improvement aftereffects onrhizosphere soil environment by monoculture and intercropping, it was found thatsynergy of two mycorrhizal fungi and intercropping could improved the soilmaturation degree, and the other two mitigated soil degradation level. AMF hadsignificant effects on the ecological reconstruction of the mine subsidence land,providing a theoretical basis for the large-scale application of microbial reclamationtechnology. |
