Soil water is the critical factors for vegetation rehabilitation and eco-environmental construction in karst mountainous region.The dynamic changes of soil water on hillslope and in depression areas under various land use types were analyzed in peak-cluster depression areas of karst mountainous region in northwest Guangxi.The results showed that soil water(0~20cm) on hillslope was moderate variation,and had some differences among various land use types.Natural shrub and abandoned lands had higher water contents and anti-disturbance abilities than those cultivated with chestnut and Cajanus cajan(L.) Millspaugh,so the latter needed some water-conserving measures during their early growth period.Sloping land was easier to be disturbed by environmental conditions than depression,where soil water increased with the increase of depth and its changes mostly took place at surface soil layers with moderate variation.Soil water movement on hillslope was complex and slope positions had small effects on its distribution along hillslope with the same vegetation type.
