In order to master the quality of soil facilities in Hebei Binhai saline-alkali area and analyze its influencing factors，129 greenhouses of facilities were selected as the research objects，which located in Huanghua county and Haixing county in Cangzhou city，and Leting county，Luanan county，Fengnan district and Caofeidian district in Tangshan city，Hebei province. The basic information of sample points and soil samples were investigated and analyzed. The obtained data were analyzed by principal component analysis method，and then the values of cormbined load values of various indicators and their correlation were combined. The minimum data set(MDS)was established，and the soil quality index(SQI)was calculated after the soil quality index was standardized for soil quality classification and evaluation. The results showed that:(1)The MDS used to evaluate the soil quality of facilities in coastal saline-alkali areas of Hebei province included soil alkaline hydrolytic nitrogen content，soluble salt content，bulk density，fungal abundance and available potassium coutent.The soil quality was divided into five levels according to SQI，of which 52.72% soil samples were in grade I and II，and 28.68% were in grade III soil samples，while grade Ⅳ and Ⅴ soil samples accounted for 18.60%，and the overall soil quality was good.(2)From the regional perspective，the soil quality in Luanan，Leting and Fengnan was good，the soil quality in Huanghua and Caofeidian was poor，and the soil quality in Haixing was significantly different. The main MDS indexes that caused the difference of soil quality between different regions were soil bulk density and soil soluble salt content. The tillage method and cultivation mode were the main factors affecting soil bulk density change.(3)This paper mainly considered four factors affecting soil quality，namely planting system，tillage method，fertilization and irrigation. Huanghua and Haixing had generally high soil salt content and low soil quality due to high salinity of irrigation water. It involved excessive nitrogen and phosphate fertilizer input in the study area，resulting in serious excess of soil available phosphorus，which had potential environmental risks.(4)With the increase of planting years，the abundance of soil bacteria decreased significantly，and the abundance of fungi first decreased and then increased. The abundance of fungi in greenhouse facilities during the planting years of 10-15 years was the lowest，and the abundance of fungi would decrease with the increase of soil salt concentration，and fungi were more susceptible to salt inhibition than bacteria.
