Abstract: Level terrace in Chunhua was the system studied object, fallow sloping field was the check, and their soil moisture variety was dynamic monitored. This research discovered that soil pondage of level terrace were less than fallow sloping filed because of crops’ absorbing and using, and evaporation. There were four seasonal period, they were storing moisture period, rapidly missing moisture period, recruiting moisture period and slowly missing moisture period, respectively, and there were 3 layers, fast changing layer, activity layer and relatively stabilization layer, on terrace soil profile. Rainfall, topography and physiognomy position where terrace located, land utilized mode, terrace width, and planting life affected terrace soil moisture in different degree. In monitoring time, except terrace surface layer had a phenomenon of soil moisture under available water, others were in the range of available water, whenever it was abundance year or year of low water, available, medium available or readily available water of terrace soil can satisfy crop demanding for growth and non-growth cost.
