In the recent 20 years, soil physics in China has developed fast, and contributed the papers published in high-reputed international journals from 5% up to 30%. These researches mainly focus on soil hydrological processes and scaling transform, soil physical quality and sustainable agriculture, water-heat-salt transport and ecological regulation, contaminants transport and numeric modeling. This paper reviewed the state of the art of these four fields, and pointed out knowledge gaps and future perspectives. These developments result not only from national demands, applications of new technology and methodology, but also from the integration and convergence of multi-disciplines. Although soil physics in China has made a great achievement, she faces the shortage of original researches and the weakness of instrument development. One the other hand, she has many opportunities to develop further as solving the requirements from food security and ecological environment security.
