The purpose of this paper is to put forward solutions to farmland-leveling precision evaluation, especially slope farmland, in land development and consolidation. Methods of theory study and field experiments, method study and technology study were jointly employed. The technological procedures of farmland-leveling precision evaluation and the algorithm of farmland-leveling precision and farmland gradient were designed, and a software was developed. The farmland leveling precision evaluation system, proved by experiment, can effectively and quickly provide quantitative assessment to land leveling conditions.
