In the northwest desert region of China， except for a small number of resource industries， most of the oasis areas are dry agricultural areas， and the current economic development mode is mainly watersaving integrated agricultural development. The reality proves that the watersaving agriculture has greatly slowed the original amount and speed of local economic development. At the key period of the currently winning of the construction of allround and welloff society， the implementation of the integrated development mode of sand treatment， tourism， ecology and oasis culture can not only save a lot of water resources for agricultural farming but also boost specific desert tourism consumption to drive sand industry to continuously develop， which is the new idea for agricultural structure reform at supply side in northwest desert and oasis regions and which is expected to become a new economic growth point along “the Belt and Road” to promote healthy and sustainable development in desert and oasis regions.
