Based on fixed observation on hillslope in red soil region,the spatio-temporal dynamic change of soil water potential in the oiltea camellia woods and their natural rehabilitation lands were analyzed.The results showed that soil water potential and its variation coefficient increased with the increase of soil depth,and soil water potential in the drought season was lower than that in the rainy season.The dynamic change of soil water potential during the process of redistribution was influenced mainly by rainfall amount,and its range and velocity below the depth of 30~110 cm in the oiltea camellia woods were higher than those of natural rehabilitation lands.The change of soil water potential intensified from 0~10 cm and 0~20 cm to 0~30 cm in natural rehabilitation land when vegetation coverage increased gradually.Zero flux planes had cyclic process between disconvergent of zero flux planes and convergent of zero flux planes from surface layer to deep layer during rainfall infiltration and redistribution,and the types and transformations of zero flux planes of oiltea camellia woods were more complicated than those of rehabilitation lands.
