Abstract: Based on the introduction of the major objectives and technical ideology of the western precision agriculture and the comparison of the Chinese agricultural eco engineering with the precision agriculture for similarities and differences, it is recommended that the study on agricultural eco engineering should confront problems that might occur during its development. To solve them it should absorb relevant principles and methods from the precision agriculture, make more efforts in the aspects of standardization of theories, modernization of means, automatization of monitoring and control of the process augmentation in hi tech contribution, organic combination with information technology and mechanical engineering, and increased workability of engineering designs, and promote informationization and epistemization of designing and management of agricultural eco systems so as to gradually form an agricultural eco engineering technical system based on information technology, biological technology and mechanical engineering equipment. 

Key words: agricultural eco-engineering, information technology, precision agriculture
