Abstract: The laser-controlled precision land levelling technology is based on the modern high technologies, such as laser-controlled technology, GPS and GIS technology, and advanced mechanical manufacture technology, which consists of the modification and promotion of the traditional land levelling technology. The application of the laser-controlled land levelling technology could improve agricultural field microtopography condition obviously. Therefore, the irrigation efficiency and irrigation uniformity could be increased at the large scale under surface irrigation condition, resulting in water saving, yield increasing, labour saving as well as raising of the land application efficiency. The application frame of the laser-controlled land precision leveling technology under the current conditions in China was presented, the main research works and related results obtained in recent years were summarized, and the development tendency and the further researches for laser-controlled land levelling technology were discussed.
