Abstract：Soil water is of great significance in the formation,transformation and consumption of the water resources and has close relationship to agriculture,hydrology and environment,so that the soil water research has been drawn more and more attention and made great progress.In this paper,the progress and achievements in soil water research were reviewed,and the development of basic theory,heterogeneity and its application in this field were discussed.The concept of soil water has been developed from the view of original morphology to the present view of energy.Many new technologies have been introduced into the research of soil water,and the study methods focus on practical application.The research field of soil water has been expanded much.Status of research on soil moisture variability from different scales including slope,catchment and region also was reviewed and three main approaches to the effect of environmental factors on soil moisture are summed up.A new recognition of "soil water reservoir" is put forward and the value of research in this area is evaluated and the further research is looked ahead.
