High standard basic farmland construction is now an inevitable choice. With consideration to the literatures and the experience of high standard agricultural land consolidation engineering in the past years, the concept and goal of high standard agricultural land consolidation engineering were discussed, and then its main technical essentials were summarized. Finally the authors made an outlook on the development trend of the high standard agricultural land engineering technology. This study could provide reference for constructing the high standard basic farmland in China, and has great significance to promote agricultural modernization.
