Soil moisture content in the karst cluster-peach mountains is a key factor to control hydrology and environment of the area.The wide distribution of rock has the profound impacts on soil moisture movement and its distribution.Study of soil moisture distribution plays an important role in hydrologic dynamic and eco-hydrology.In this study,soil moisture contents in the typical karst cluster-peach mountains in Puding County,Guizhou Province were measured by TDR.The influences of rock are then revealed based on the observed data.Results show that soil moisture content is lower in underlying strata and higher in soil layers above strata due to thicker soil layers,and however,it is lower if soil layer becomes thin.Soil moisture content is found to be higher near the dissolved stone because of the recharge from precipitation.Soil moisture content in the soil layers with gravel is higher because gravel within soil may increase water infiltration into soil.However,the influence is reduced with increasing depth.
