The ecological restoration area in the west part hill area of the Loess Plateau was chosen for the object in this work. Neutron probe was used to test the moisture change in Pinus tabulaeformis forest soil under different rainwater harvesting and water conservation measures. The dynamic characteristics of soil moisture under different rainwater harvesting and water conservation measures, the deficit and compensation of soil moisture before and after rainy season were analyzed. Results show that soil moisture storage capacity under different rainwater harvesting and water conservation measures is significant different. The soil moisture under slope water harvesting measure is greater than those with other measures.The soil water storage deficit is alleviated under seven measures in July. Soil water storage deficit from 0～100cm is alleviated under slope water-harvesting and slope water-harvesting with water harvesting groove reversed. Results of this study indicate that slope water-harvesting has a significant effect on the effective use of precipitation. Film mulches mulch has a negative impact on the recovery of the surface soil moisture，but has an obvious effect on water conservation of deep soil moisture.Wallow-tail type runoff collecting pit is ineffective in increasing the efficiency of precipitation use and compensation of soil water storage deficit.
