摘 要：
基于田间试验数据,从高程标准差、测点高差分布和农田表面三维地形图等3个角度对1PJ-2500型激光精平机的平地作业精度进行分析评价。研究结果表明:在土地平整中,使用1PJ-2500型激光精平机可以获得高精度的土地平整效果,精平之后的平均田块高程标准差降低到1.54cm,田块表面96.77%的测点主要分布在ED<3 cm的区间内,农田表面平整度和测点高程分布均有大幅改善。

摘 要：
Based on the typical Field data,the paper evaluates the working precision of 1PJ-2500 laser leveling machine.The paper was analyzing in three points: Elevation standard deviation,measurement points Elevation distribution,and 3-dimensional landforms map of the plots surface.The result shows that high-precision land leveling effect could got in using 1PJ-2500 laser precision leveling machine,the average elevation standard deviation achieve at 1.54cm,96.77% measurement points of plots surface were in Range of ED<3cm.The farmland surface roughness and Elevation distribution have substantial improvement.
