The aim of this paper is to study how to evaluate farmland productivity through the combination of GIS technology with tradi- tional methods of evaluating soil productivity.An evaluation method based on GIS is then put forward.In allusion to the actuality of the farmland resources in Tieling County,important influencing factors such as nutrient condition, soil physical and chemical character, pro- file situation and land situation are analyzed thereafter.On the basis of establishment of farmland resources information database, soil productivity assessment system and model are set up using AHP. A comprehensive evaluation and grading on the farmland in Tieling are accomplished in an effort to provide reference for the rational use of farmland resources.
