[ObjectiveH The response characteristics of soil, crops and microorganisms at the fracture zone of the subsidence area was studied in order to provide a theoretical basis for ecological damage reduction and self-repair in the subsidence area. Methods] The coal mining subsidence area of Shendong was taken as the research site, the response characteristics of soil, crops and microorganisms at the fracture edge of the subsidence area within 1 5 days from LFC to LFW were studied by using field monitoring and indoor analysis. [Results] The surface soil moisture content within the depth of 10 cm was completely lost and could not be recovered after 3 days of subsidence and fracture generation, soil moisture was also affected within the depth of 20 cm, but not significantly. The development of fracture in the subsidence area had a disturbing effect on soil physicochemial indexes and enzyme activities, but it was not significant. The development of fracture in the subsidence area caused disturbance to soil microorganisms, which reduced the uniformity and relative abundance of soil microbial communities, the dominant phyla of bacteria with a relative abundance greater than 1 % were lacked of Armatimonadetes and Firmicutes, the dominant phyla of fungi with a relative abundance greater than 1 % was lacked of Blastocladiomycota. RDA analysis showed that soil T, ()M, AK, AI}, pH, and AN were the critical factors driving the changes of soil microbial community structure. Pearson correlation analysis showed that the crops at the fracture edge of the subsidence area were significantly stressed by soil water and temperature, and the contents of SS, SOD, SI〉and MAT) in the crops increased significantly, and the stress degree was corn >• cabbage > potato, Conclusion] Fracture development in the area of the subsidence is the source driver of the linkage response of soil environmental factors, microbial communities and crops in the fracture margin zone.
