The large amount of calcium and magnesium ions leads to phosphorus fixation and limits plant growth in calcareous soil.Adding different types of phosphorus fertilizers can improve the inorganic phosphorus forms in soil and influence the phosphorus availability.However，the comprehensive impact of phosphorus fertilizer addition on the form of inorganic phosphorus have been unknown.To clarify the types and amounts of phosphorus fertilizer added to calcareous soil，the published.41 test data which met a series of conditions were integrated and analyzed by using MetaWin 2.1 software according to three types of phosphorus fertilizers including ammonium phosphate，calcium superphosphate and potassium dihydrogen phosphate，as well as four kinds of concentrations(P2O5)including low(not exceeding 60 mg/kg)，medium(60-120 mg/kg)，sub-high(120-180 mg/kg)，and high concentration(exceeding 180 mg/kg).The results showed that:(1)Compared with not applying phosphorus fertilizer，the average effect size of dicalcium phosphorus(Ca2-P)，octacalcium phosphorus(Ca8-P)，decacalcium phosphorus(Ca10-P)，iron phosphorus(Fe-P)，aluminum phosphorus(Al-P)，and stored phosphorus(O-P)after applying phosphorus fertilizer were 0.0104-0.7457，respectively.After the application of ammonium phosphate，calcium superphosphate and potassium dihydrogen phosphate，the average effect size of Ca2-P were 0.5446，0.66 and 1.0326，and their ratio to the total inorganic phosphorus were 42.47%，44.72% and 66.56%，respectively；(2)The significant positive effect on phosphorus forms when applying phosphorus fertilizer at low and medium concentrations was found，whereas no significant change in inorganic phosphorus forms applying at sub-high concentrations，and the application of high concentration phosphorus fertilizer showed significant changes except for Ca10-P and Fe-P.The Ca2-P average effect size were 0.6381，0.4503，0.7109 and 1.4949，and their ratio to the total inorganic phosphorus were 37.14%-51.26% at low，medium，sub-high，and high concentration phosphorus fertilizers，respectively.In a short，potassium dihydrogen phosphate with the concentration not exceeding 60 mg/kg were suitable in calcareous soil.
