Based on fixed field observation for five typical landuse modes

this paper analyzed the effects of different landuses on its rainfall utilization and water balance.The main results were reported as follows.(1)The difference laws of steady soil water consumption in grassland and a higher ability in sufficient use of water stored in deep soil layer in tea garden and the restoration area showed that the characteristics of soil water utilization in different landuse patterns were different with different seasons and soil layers.(2)Evapotranspiration hold more than 83%of input(rainfall)

which was the most important output part of water balance in 100 cm plough layer.Evapotranspiration on cropland was the lowest and runoff on it was the highest

but those in the restoration area were reverse.(3)An optimal model of rainfall utilization on sloping land in red soil region must be constructed for reducing surface runoff and improving the utilization rate of rainfall

so the compound management of cropping forestryher bage and the tillage methods of broad base terracing would be the best choice.
