In order to explore the present situation of soil nutrients in soda saline-alkali land in Xiliao river basin，soil nutrients were monitored in two typical soda saline-alkali land areas i.e. Huatugura town(Area 1)and Tubuxinsumu(Area 2)in 2020. Factor analysis，cluster analysis and kriging interpolation were used to evaluate individual nutrients and comprehensive grade. The results showed that，for the pH，81% of Area 1 was in the range of 7.5～8.5，55% of Area 2 was in the range of 7.5～8.5，and 37% of Area 2 was in the range of 8.5～9.5. As for the total salinity，the proportion of two zones ranged in 1.0～3.0 g/kg accounting for 73% and 65%，respectively. The contents of organic matter and total nitrogen in the two zones were low，and the proportion of cultivated land with medium and above grade was less than 7.70%，19.23% and 2.63%，25.00%，respectively，and the contents of organic matter and total nitrogen in most cultivated land were relatively deficient. The contents of available phosphorus and available potasium were higher，and the proportion of medium and above arable land was 84.60%，96.15% and 77.63%，96.05%，respectively. The factor analysis results showed that the factor 1 in Area 1 and Area 2 mainly represented organic matter and total nitrogen，which were the main factors affecting soil nutrients. The results of IFI cluster evaluation showed that the proportion of cultivated land above medium grade was 38.47% and 65.79%，respectively. The results can provide theoretical reference for improving soil nutrients in soda saline-alkali area of Xiliao river basin.
