Abstract:: The article studies and discusses influencing factors about variation of soil water content in Puding typical karst rocky desertification region. Changes of soil moisture affected by weather rocky desertification slope vegetation soil properties and other factors is analyzed in brief. Research shows: precipitation is the main controlling factor of soil moisture; soil moisture content and humidity were positively correlated, meanwhile negatively correlated with air temperature. Different developmental levels of rocky desertification plots sort order of the size of the soil moisture: Potential rocky desertification>mild rocky desertification>moderately rocky desertification. Vegetation coverage was positively correlated with soil moisture content. Soil moisture decreases with the slope increasing. Soil moisture content was positively correlated with soil thickness. Soil texture produces certain influence on moisture infiltration into soils, while the soil chemical properties have little influence on the soil water content.
