Abstract: The research work of soil water movement is based on the capillary theory, which will be important continually in the future.In the view of the research method,we know that mathematical model and digital analysis are becoming the most important upsurge, besides the traditional observative experiment, practical measurement and physical simulation.The use of isotopic trace has shown up many new problems and widen the field of soil water movent research work.Recently,many kinds of lysimeters have been established and many active monitering works have been done in our country.we can say that the research of soil water motion develops rapidly.At the same time,indoor simulation work begians now.n fact, the combination of the two ways gives us a very deep understanding on soil hydrology factors and its variation system.We have also achieved some new results in evaporation and infiltration by analyzing the fundamental theory of soil water movement, which enhaced the explanation of water transposition system and funded the base of water resource evaluation.The research work of soil water regulation and its effective use, which we did in order to meet the need of production,has opened up a new way to save the insufficency of water resourcesOtherwise, the soil water motion is a very complicated problem, affected factors are numerous, time and spec vary highly indeed.It is very necessary for us researchers to continue to deal with the basic theory of soil water movement, exploit the new apparatus and research methods, solve the practical problems ef f ectively.0ur task is very heavy and far-reached.
