Some basic indicators such as capillary moisture content , field water holding capacity , field mois ture content , available water in different depths of soil , as well as soil moisture content under different water potential were measured respectively. Capacity as well as spatial and temporal distribution in the soil moisture utilization of three year pat terns with high , normal and low rainfall were analyzed by using isogram mapping which was intuitive and effective. Key words 　Arid land of wheat ; Year pattern ; Property of soil water ; Spatial and temporal distribution of soi
