This paper studied transformation among atmosphere water,surface water,soil water and ground water in 8 aspects,which is important for water resources assessment,water requirement prediction,reasonable water resources development and utilization and water saving irrigation.

The theoretical model to reveal the mechanism of delayed gravity response is established on account of the effects of detention of water by capillarity and boundary friction in the unsaturated zone and elasticity of aquifer skeleton with falling of ground water level.

The results show that(1)developed calculation models are accord with the control conditions;(2)as for a given depth of groundwater table,the relation of phreatic evaporation and water surface evaporation is nonlinear and the phreatic evaporation is close to the ultimate rate when water surface evaporation reaches the infinity great;(3)the threshold of groundwater depth doesn’t exist theoretically.
