Abstract: It's considered by the authors that there are three kinds of problems in utilization of soil water resources in the Loess Plateau: 1.formation of a definite thickness of dry soil layer due to intensive water absorp-tion and consumption;2.emergence of a certain depth of PWP-layer,and 3.existence of water deficiency and its low utilization efficiency,which influences the eco-environmental balance.It' s reasonable to uti-lize soil water in accordance with concrete condition,enhance water utilization efficiency and combine wa-ter utilization with its restoration.
