Summary:This study aimed to investigate the characteristics of soil total porosity and various factors affecting soil water content in eucalyptus plantation, thereby providing references for soil water utilization in eucalyptus planting in the red soil hilly region of South China. In the same climatic region, soil samples were collected from surface soil layer, illuvial horizon and parent material horizon in the upper slope, middle slope and lower slope of eucalyptus plantation, native forest and pine forest, respectively, to determine the soil porosity and soil water content and analyze changes and various influencing factors of soil water content in horizontal and vertical direction. Average soil porosity in eucalyptus plantation, native forest and pine forest was 45.9%, 41.4% and 55.3%, respectively; soil water content in these three forest stands was 13.3%, 13.4% and 15.5%, respectively. Total coverage of canopy layer, herb and litter layer is one of the most critical factors affecting the changes of soil water content in surface soil layer of forest stands.
