在常规土地平整方法与激光平地技术组合应用实践基础上, 对两种平地方法的平整效果、作业效率及成本费用进行分析. 结果认为, 为达到费省效宏的组合平地应用形式, 在土地原始平整状况较差的渠灌区, 应首先采用常规平地方法进行粗平, 当田面平整精度与平地期望值的差值接近3cm 时, 再利用激光精平方法完成土地平整工作. 对田面平整度较高的井灌区, 也可直接采用激光平地技术完成土地精平.
Based on the practical application of the combination of conventional land leveling and laser leveling techniques, the leveling effect, operating efficiency and cost of the two land leveling methods were analyzed. The results show that in order to achieve a combination of land use efficiency and cost-effective form of flat land, the original formation of the poor drainage conditions of the original irrigation area should be flat with the conventional flat ground method, when the formation surface roughness and the difference between the expected value of close to 3cm, Then use the laser leveling method to complete the formation of the land. On the field surface roughness higher well irrigation area, but also can be directly used laser leveling technology to complete the land Jingping.
