Abstract In recent years，due to unreasonable irrigation and other environmental factors，soil salinization is becoming increasingly serious，which seriously affects the growth，development and yield of vegetable crops，and limits land use．Salt stress changes the growth and development processes of vegetables，including net photosynthetic productivity，respiration，cell membrane structure and various enzyme activities．In this review，the effects of salt stress on the apparent morphological changes of vegetable crops and the physiological and biochemical indexes of plants were reviewed，and the physiological（including osmoregulation，ion regionalization，and antioxidant metabolism）and molecular（transcription factor，ion homeostasis-related genes，antioxidant genes，and miRNAs）regulations of vegetable response were discussed．The evaluation methods of salt tolerance in various vegetable crops were summarized. The research prospects of salt tolerance in vegetable crops were further prospected．
