Abstract: Surface layer soil samples from paddy rice field, dryland and abandoned land were collected in the main saline-alkali irrigated area of western Jilin Province. Distribution characteristics of total fluoride (TF) and dissolved fluoride (DF) were identified. The subarea was divided based on the classification of DF. The reason of higher soil DF concentration was discussed. The findings show that the arithmetic mean concentrations of TF and DF in soil in the region are 365.26 mg·kg⁻¹, 14.45 mg·kg⁻¹, respectively. The concentrations of TF are at a mid-low level and significant difference (P<0.05) among irrigated areas, while DF concentrations are at a higher level and no significant regional difference. Land use affects soil TF and DF concentrations to some extent. Both geological-geomorphological setting and saline environment impact the formation and enrichment of DF in soil. Environmental risks of DF from saline land reclamation cannot be ignored. Application of fixing agent of DF is necessary to control the eco-environmental effect of DF.
