摘　　要：研究目的:提出土地开发整理中农田平整精度评价特别是坡式田块平整精度评价的解决方案。研究方法:理论研究与野外实验相结合,方法研究与技术研究相结合。研究结果:设计了农田平整精度评价技术路线和田面平整度、田面坡度的算法,并开发了软件模块。研究结论:试验表明,运用农田平整精度评价系统,可在野外方便、快捷地对农田平整精度进行出量化的评价。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.
