| Abstract: | The insufficient water resource and growing population has added very pressure to agricultural production. Seeking to develop the relatively abundant land resource in the region of dryland agriculture becomes the important method to satisfy the increasing demand. This paper has discussed the limited factors of sustainable development of dryland agriculture, relationship between water and fertilizer in dryland, the effect mechanism of water and fertilizer coupling and the meaning of water and fertilizer coupling for dryland agriculture sustainable development. |

| Keywords: | water and fertilizer coupling dryland agriculture water use efficiency sustainable development |
