Abstract: Soil moisture is one of the main limiting factors for vegetation restoration in Karst Areas.This paper analyzed the influence of vegetation types and soil properties on soil moisture by studying the soil moisture characteristics,soil pore conditions and soil carbon,nitrogen and phosphorus contents of three main vegetation types in the limestone area of Huaxi Reservoir.The research results have certain guiding significance for the ecological restoration of Karst Areas.The results showed that the water content of surface soil was shrub＞bamboo forest＞grassland,and that of 20-40 cm soil layer was shrub＞grassland＞bamboo forest.The total porosity of the surface soil shrub was large,higher than 58%,and the total porosity of the grassland was low,and the bamboo forest was in the middle.The permeability coefficient of bamboo forest was significantly higher than that of shrub and grassland.The water storage capacity were shown as shrub＞grassland＞bamboo forest,and more water was stored in 20-40 cm soil layer.Correlation analysis showed that soil bulk density and pore condition had a very significant impact on soil water storage capacity,and capillary water capacity and permeability coefficient had a very significant impact on soil water content.There was significant or extremely significant correlation between soil organic carbon content and soil bulk density,tolal porosity,capillary pore,capillary water capacity,drainage capacity and permeability coefficient.Therefore,vegetation types and soil properties in Karst Areas had an impact on soil water,affecting its water availability and water storage capacity,thus affecting plant growth.In the study of soil moisture characteristics in Karst Areas in the future,we should pay attention to the influence of topography and climate on soil moisture.
