Fusarium-induced root rot of Carya cathayensis(C. cathayensis) is a typical soil-borne disease that has severely damaged the Carya cathayensis industry in China. Understanding the interaction among soil microbial communities, soil characteristics, and pathogenic bacteria is very important for the ecological prevention and control of Carya cathayensis root rot. We used Miseq Illumina highthroughput sequencing technology to study the microbial community in the rhizosphere soil of healthy and diseased Carya C. cathayensis, quantified the abundance of bacteria, fungi, and pathogenic fungibacteria, and combined these with soil chemistry and enzyme activity indicators to analyze the characteristics of healthy and diseased rhizosphere soils. We found that the pH 、 soil organic carbon(SOC)、available nitrogen (AN)AN、available phosphorus (AP)AP、available potassium (AK)AK、N-acetyl-β-D-glucosaminidase (NAG)NAG、β-glucosidase (BG)BG、 fungal gene copy numberfungal abundance、bacterial community diversity and network complexity of the diseased soil were significantly lower(P
