Regional salinity management based on shallow groundwater controlling : a case study in the north china plain

[ABSTRACT] This paper deals with regional salinity management of the North China Plain. The authors of present paper paid careful attention to the fact that the basic characteristics of salinity dynamics are in close relation to water. Particularly in semiarid and semihumid flat areas, the water is not only a driving force for salts, but also the most important state variable having a decisive influence on soil salinity. On basis of such principle, the authors studied the approaches to control the salinization in the North China Plain.
