Abstract： To investigate the efect of long-term vegetable production on soil calcium nutrition status，a survey andanalysis wasconducted on15 plots of long-term vegetable production distributed in diferent regions of Fujian. The research results showed that the exchangeable calcium content was 256-923mg/kg （with an average of 608 mg |kℓ⟩ g）and 20.00% belonged to low levels，and 80.00% of soil calcium nutrition belonged to medium levels，without high levels.There was a highly significant negative correlation betweensoil exchangeable calcium content and pH.There was a highly significant positive correlation between soil exchangeable calcium content and organic matter.There was a negativecorrelation between soil exchangeable calcium content and available potasium，available phosphorus，and available nitrogen.The soil pHand organic matter were the main factors affecting the effectiveness of soil calcium nutrition.
