Abstract

Using stable isotope investigated the soil moisture response of precipitation pulse in a typical desert area in the middle Hexi Corridor, China. The 18-oxygen of precipitation and rainfall distribution showed significantly seasonal effect. There were more rain frequency and heavier 18-oxygen of precipitation in summer than in winter. Precipitation input into soil by the way of pulse, and the soil water content and 18-oxygen showed different changes among soil layers after different precipitation. The 8-oxygen of soil water and resident time varied following the soil depth. We found that the precipitation moved through soil layers by piston displacement in this desert area. The soil moisture regulated and controlled by rainfall events, but the deeper water was little influenced by light rainfall. Although the frequency of heavy rainfall was low in the desert area, the deeper soil water could acquire effective recharge and have important significance in maintaining the development of the desert ecosystem.
