Abstract: Water shortage is an important factor that restricts food production in arid and semi- arid area in North China. Biological water –saving is a key link in improving crop water use efficiency. The paper summarized signification and studies of differency mechanism of WUE among differenct species of crops, and next study advisies were put forward: in Huabei Plain of north China, we should study anniversary WUE of deep soil moisture under deficit irrigation conditions. At present, we should furtherly study physiological regulation mechanism of high-WUE crops and evaluation system of drought-resistancing and water-saving for cultivating high-WUE species.
