| Abstract: | Abstract This paper presents the conception of dynamic soil hydrology and its develop-ment. The research progress on its main aspects, such as soil permeability, root systemabsorption, evaporation and water balance are summarized. The role of dynamic soil hy-drology theory in the establishment of protective forest system is discussed. The optimaldensity of protective forest system in loess plateau, and the improvement of lowpoletrees of poor growth are studied. |
