Based on the background of water distribution of Heihe River

it analyzes the urgent situation of water shortage and the effects of the land use structure on it in the middle reaches of Heihe river after water distribution. Because of the close correlation of the rational application of water and land resources in the arid area

reasonable land use structure can make water more effectively used. Due to the above reasons

it argues that the water shortage restriction should be solved by reasonable optimization of land use structure; in addition

it also puts forward the main direction of land use optimization.
