| Abstract: | Soil moisture is important basis of land appraise and agricultural water saving technology research, and soil water has become one of the research hotspot in the world. According to the soil water data at 3 national county levels and based on Surer7.0 technology, the seasonal and vertical variation of soil water contents in typical sites during the last 21 years and different precipitation years are analyzed. The analytical results and conclusions will provide scientific basis for developing high-efficiently water-saving agriculture in the Loess Plateau gully and hill region. |
