Title: CHARACTERISTICS OF SOIL MOISTURE DISTRIBUTION AND ITS INFLUENCE FACTOR IN THE KARST CLUSTER-PEACH MOUNTAIN
Abstract: Soil moisture content in the karst cluster-peach mountains is a key factor controlling the hydrology and environment of the area.The study of soil moisture distribution and regularity plays an important role for soil and water loss prevention,rocky desertification control and environment recovery in theory and practice.In this study,the soil moisture contents in typical karst cluster-peach mountains in Puding County,Guizhou Province,were measured by time domain reflectometry in many locations with different vegetation covers,landform,soil characteristics,land surface slopes and rock distributions.Their influencing factors were revealed on the basis of the observation data.The results show that soil moisture content has a significant increase tendency from the mountain higher to lower portion for any different land-uses in the mountains.Soil moisture content increases significantly in the deeper soil layers but decreases in the areas with sharper slope surface.Soil moisture content under vegetation canopy is greater than that in the bare sites,and this influence becomes weak when the land surface vegetation changes from forest to shrub and grass.Soil moisture content in the soil layers above the rock is higher with the thick soil layer and lower with the thin soil layer.
