Abstract:: An experiment was conducted to study the interactions between capillary porosity, temperature and moisture, and the seasonal effect of four treatments including straw, mulching litter mulching, gravel mulching and open ground on forest soil water content among three different densities(50%, 70% transplanting and without transplanting) in 6-year-old Ligustrum lucidum Ait. plantation in Jiangdu in order to determine the optimal management strategies to reduce the water consumption of urban green space. Result showed that mulching treatments increased water content of surface soil. Among these treatments, straw mulching was the best in April and November, while litter mulching was the best in July; compared with the control plots, gravel mulching reduced the soil moisture differences between different soil layers. With the increase of transplanting strength, the enhancement effect of mulching treatments on surface soil was weak and soil water holding capacity decreased.
