With methods of limited areas, root systems of plant individuals were limited in a specific range, providing definite spatial boundary and solid basis for calculation of water requirement needed by plant individuals. On the basis of calculation of amount of water requirement, areas needed by every species to ensure enough water requirement are as follows: Populus simonii is 80.3m〓, Ulmus macrocarpa is 35. 4m〓, Artemisia halodendron is 7. 0m〓, Salix gordejvii is 11. 2m〓. Prunus armeniaca is 15. 2m〓, and Caragana microphylla is 15. 6m〓. The corresponding rational density of plantation which can maintain soil water balance and can ensure plantation stability is 125 individuals/ha for Populus simonii, 285 individuals/ha for Ulmus macrocarpa, 625 individuals/ha for Prunus armeniaca, 625 individuals/ha for Caragana microphylla, 833 individuals/ha for Salix gordejvii, and 1428 individuals/ha for Artemisia halodendron, respectively.
