This paper aims to understand the basic fertility and the reclamation suitability of the adjustable land in Jiulongpo District of Chongqing. 3S techniques, field surveying and sampling, and lad measurement were used to obtain the information of the spatial distribution and soil properties of the adjustable land and AHP and Fuzzy methods were adopted to calculate the reclamation suitability score of the adjustable land, Frequency curve method was applied to classify the grades of reclamation suitability and four-quadrant method was used to identify the types of suitable areas. The results showed that the areas of the 1st, 2nd, 3rd 4th and 5th fertility-grade lands were 403.96 hm², 519.47 hm², 617.86 hm², 625.46 hm² and 187.29 hm², accounted for 17.16%, 22.07%, 26.25%, 26.57% and 7.95% of the total area of adjustable land, respectively. The areas of the most suitable, basic suitable, suitable and unsuitable reclamation regions were 243.42 hm², 983.55 hm², 556.64 hm² and 660.42 hm², accounted for 10.34%, 37.96%, 23.65% and 28.05% of the total area of adjustable land, respectively. The evaluation results are consistent with the field surveying results, therefore, they could provide the basis for the improvement of adjustable land and for maintaining the balance of cultivated land in Jiulongpo District.
