The temporal and spatial variation characteristics of soil moisture in typical slope and gully of Jiulongquangou small watershed were studied in the hilly and gully region of the Loess Plateau of China. The variation of soil moisture in the 0-30 cm layer on the surface of the hilly and gully region of the Loess Plateau is greater than the variation of soil moisture in each layer between 40 and 100 cm. In the study area, the model parameters such as coefficient of variation (Cv), nugget (C0), sill (C0+C), spatial degrees of freedom(C0/(C+C0)) and variable change can be used to quantitative analysis the spatial varying law. On the slope surface, the average soil water content and the coefficient of variation are negatively correlated, and can be approximated by an exponential function, while the two are positively correlated in the gully.

Drought monitoring is one of important researching areas. The soil moisture data retrieved from AMSR-E and SPI both can be employed as the indexes for drought monitoring. In this paper, they are compared in temporal and spatial variation in the hilly area of central Sichuan basin for 2006-2008. The results show that in general they agree well in temporal and spatial distribution. They both indicate that the hilly area of central Sichuan basin was wetter in the spring and summer and drier in winter. Besides, they become greater from the northwest to southeast of the study area.
