Abstract: Spatiotemporal variation of soil moisture represents the differentiation and diversity of soil moisture properties at different scales of time and space, which is related to the joint effects of several environmental factors, including vegetation, land use, meteorological factors (e . g . , rainfall), topography and soil at multiple scales. However, the key scale and dominant factors are differed with different time, space and scale. This paper reviewed the studies on the spatiotemporal variation of soil moisture and its relation to the environmental factors, with the focus on the studies of the Loess Plateau in China. The issues worthy to be further studied were also put forward, including the spatiotemporal variation of soil moisture and its relation to environmental factors at multiple-scales, scaling-up or scaling-down of soil moisture spatiotemporal differentiation, and determination of key scales and corresponding affecting factors.
