Jinlong Duan, Xuelei Zhang, Weidong Li, Bin Li. Application and Development of Studies on Pedodiversity Theory and Methodology in China[J]. Advances in Earth Science, 2014, 29(9): 995-1002.

As one of the most recently developed research field in soil geography, pedodiversity theory with its methodology is widely spread and getting more attention at home and abroad due to its application in quantitatively describing the spatial variability and distribution pattern of regional soil resources. In this paper, after a brief review of the emergence and development process of pedodiversity in foreign countries, an intensive research has been made in analyzing the development process in the past 15 years of pedodiversity studies in China before summarizing the development characteristics and trends of Chinese pedodiversity research. In recent years, pedodiversity studies in China have combined pedodiversity with many different elements such as land use, nested analysis, urbanization process and water resources, making this research field more open and practical. It is believed that the Chinese pedodiversity research could be divided into a causation and exploration period and an extended application period due to their differences on research period, content and purpose which the first period is from 2001 to 2005 and second from 2005 to now. And besides the classic diversity measurement methods, such as richness index, Shannon entropy and Pielou index, the new proposed index of soil spatial distribution diversity could provide an important data supplement for the classic methodology. Therefore, the pedodiversity topic still has strong and broad application space and development prospects in the soil geography and other related subjects.
