Abstract:
With 30 abandoned lands in hilly area in region of Northern Shaanxi as experiment object,during their natural recovery process，spatial sequence generation of timeseries were used,the monthly and yearly alteration of their soil moisture and the temporal variability of their soil bulk was analyzed.The results showed that the abandoned arable land made the soil bulk density become smaller；in the vertical profile，soil moisture increased with the increase of the soil depth；the changing tendency of soil moisture of abandoned arable land was shady>semi shady>semi sunny slope>sunny；monthly changing tendency of soil moisture of abandoned arable land was July>August>September>October>May>June；the inter annual dynamics of soil water content was that soil moisture of 2005 was higher than that of 2006 and 2007.In the three years from 2005 to 2007，the soil moisture was higher in the early succession stage，then decreased.
