[Objective] The aims of this study are to increase the efficiency and accuracy of the potential evaluation of newly-increased cultivated land from farmland consolidation on the scale of county(city), reduce the cost of the evaluation, and to provide reference for the overall planning of land use and land remediation planning. [Methods] A new technical system based on the GIS spatial analysis method was used. Based on data from the second investigation of land-use and the general land use planning, combined with the experience from land consolidation, we first developed new principles and perspectives for the potential evaluation, then determined the scale of agriculture land to be processed, then measured the area of the newly-increased farmland, and then calculated the coefficient of newly-increased farmland, finally delineated the fivepotential zones. [Results] The potential of newly-increased cultivated land from farmland consolidation in Wenzhou City is reasonable and more practical. [Conclusion] The empirical study showed that the technical system could provide a proceeding operation of inputting the basic data, measuring and evaluating the potential, and outputting the results. Such technical system not only has the advantages of improving the efficiency and reducing the cost of the potential evaluation at the same time, but also well adjusts the current land management practice, which presents considerable promotional value.
